Macquarie Duvernay Shale Research Report
Do the ‘Dew’vernay! CANADA Big liquids. Big costs. Big payoff. Duvernay shales – Canada’s Eagle Ford Over the next decade, we believe the Devonian-aged Duvernay shales will emerge as one of the most promising oil/gas resource plays in Canada. In fact, we see these shales as having the potential to be Canada’s answer to the prolific Eagle Ford shales in south Texas. Eagle Ford producers, such as EOG Resources, Chesapeake, Anadarko Petroleum, Petrohawk (now BHP) and Pioneer, have significantly ramped up activity, moving the rig count in that area from essentially nil in late 2009 to 140+ rigs today. In our view, the Duvernay shales are at the precipice of being a timeless unconventional resource play, characterized by the right geochemical, petrophysical, and mineralogical parameters.

Unit prices since 2009 have averaged C$200-400/acre, with some land in Pembina and Kaybob fetching nearly C$5,800/acre. From an activity standpoint, there are currently 24 wells drilled or licensed to-date, including nine horizontals across the greater Kaybob and Pembina regions. For 2011/2012, we anticipate another 20+ wells to be drilled, with the most active producers being the Large Caps (ie, Encana, Talisman, Husky, Chevron and ConocoPhillips). Preliminary economics: contingent on costs and yields Admittedly, with limited data, it is difficult to formulate a type curve of any certainty. However, for our base case liquids rich gas Duvernay type curve, we assume an IP rate of 4.2mmcf/d and liquids yield of 75bbl/mmcf, generating an EUR of ~805mboe/well (30% liquids). This type curve produces a reasonable before tax NPV10 of C$8.7m, profit-investment ratio of 0.8x, and IRR of 46% based on a drill, completion, and tie-in cost of C$11m and our long-term price deck of US$90/bbl WTI, US$6.00/mmbtu Henry Hub, and US$0.95/C$. On an economic basis, the Duvernay shales rank close to the Eagle Ford, Haynesville and Fayetteville.

Within our coverage universe, Talisman Energy (TLM CN) shows up as the most leveraged Large Cap producer followed by Encana (ECA US). Among our high yield/mid cap producers, we believe Athabasca (ATH CN), Daylight (DAY CN), Celtic (CLT CN), Vero (VRO CN), Chinook (CKE CN), Bellatrix (BXE CN) and Angle Energy (NGL CN) have the best exposure to the play. On the smaller cap side, Delphi (DEE CN) has the highest leverage relative to its size, though we note its lands are located in the unproven ‘oil window’ of the play. Outside our coverage universe, we highlight Trilogy (TET CN), Mako Energy (MKE AU), Kilgore (KOG AU), Sonde Resources (SOQ CN), Longview (LNV CN), Galleon (GO CN), Yoho (YO CN) and Terra (TT CN).

Is the Duvernay Alberta’s Eagle Ford? Over the next decade, we believe the Devonian-aged Duvernay shales will emerge as one of the most promising oil/gas resource plays in Canada. In fact, we see these shales as having the potential to be Canada’s answer to the prolific Eagle Ford shales in south Texas. Eagle Ford producers, such as EOG Resources, Chesapeake, Anadarko Petroleum, Petrohawk (now BHP), and Pioneer, have significantly ramped up activity, moving the rig count in that area from essentially nil in late 2009 to 140+ rigs today. In our view, the Duvernay shales are at the precipices of being a timeless unconventional resource play, characterized by the right geochemical, petrophysical and mineralogical parameters. Building on our initial October 2010 report, ‘Going Straight to the Source’, the purpose of this study is to provide investors with a comprehensive look into the Duvernay resource play, with a particular focus on the geology, activity, infrastructure, and economics. We have also provided a detailed comparison between the Duvernay and Eagle Ford and the producers most exposed to the play. Where is the play? Fig 1 is a regional map of the Duvernay/Muskwa trend in British Columbia and Alberta. In Alberta, the sedimentary wedge is differentiated east of the Deformation Front and west of the Grosmont (upper Leduc) Shelf Edge, including the major fringing Leduc reefs to the north that demarks the Peace River Arch (PRA). The focus of our analysis is on the unconventional Duvernay shales geographically defined southeast of the Peace River Arch and northwest of the Rimbey–Meadowbrook Leduc trend in the West Shale Basin. From a geological perspective, the Duvernay shales are considered to be correlative and time equivalent to the Muskwa shales in northeast British Columbia and northwest Alberta. Industry nomenclature standards dictate that anything north of the PRA is called ‘Muskwa’ shales while anything to the south is called ‘Duvernay’ shales. We estimate the Duvernay shales stretch over ~100,000km2 across west central Alberta.

Geological overview Shale oil/gas generally refers to continuous, self-sourced resources contained in fine-grained, organic rich, low permeability reservoirs. Oil or natural gas in these particular reservoirs can be found as free gas/oil in the interstitial pore spacing/in-fracture spacing, or adsorbed in the kerogen (organic material). The best quality shales can act as the source rock, seal, and even as reservoir rock, representing a self-contained petroleum system. The sweet spots to be determined. A myriad of factors determine whether a particular shale play will be ultimately prospective for oil or gas. While pervasive over a large area, the Duvernay shales are not created equal everywhere and vary in terms geochemical, petrophysical, geological, and mineralogical factors (ie, lithology, mineralogy, total organic carbon, thermal maturity, porosity/permeability, thickness, or depth). We believe an understanding of these differences will help investors better identify the sweet spots of the play, and who is positioned most appropriately. Breaking down the Duvernay. The Devonian-aged Duvernay shales (~360Ma) are considered a major source rock for a number of Upper Devonian Alberta oil and gas pools, which include the prolific Leduc/Slave Point/Keg River reef and pinnacle pools. Total organic carbon (TOC) content in some areas is up to 20%, which is a key indicator of hydrocarbon generation potential. The Duvernay formation itself can be generally segregated into the base, middle, and upper members: 1) the base or lower member is a 20m thick black argillaceous limestone; 2) the middle member is generally a black shale consisting of skeletal reefal debris; and 3) the upper sequence is considered to be a brown bituminous shale/argillaceous limestone, with thickness in the range of >20m. We believe the base and middle members will ultimately be the most prospective target of the Duvernay formation, given the skeletal reefal debris (ie, carbonate layers) contained within. Fig 2 Stratigraphic column Source: Alberta Geological Survey, Macquarie Research, August 2011 15 August 2011 3 Macquarie Research Do the ‘Dew’vernay! Deposition. The Duvernay shale is part of the first five chronostratigraphic intervals in the Devonian Woodbend Group, consisting of the Cooking Lake, Majeau Lake/Lower Leduc, Duvernay/Middle Leduc, Lower Ireton/Upper Leduc, and Leduc intervals (see Fig 3). The deposition of the Woodbend group is thought to be consisted of a rapid upbuilding phase of shelf and reefal sediments followed by infilling of basinal areas by shale and marlstones. The Duvernay sequence is generally represented by the ‘basinal infilling’ phase, followed by significant growth in the Leduc reefs. All-in-all, the Duvernay shales are typically non-existent where the Leduc Reefs are known to be present (see cross-section in Fig 4). Fig 3 Stratigraphic cross section Source: Alberta Geological Survey, Macquarie Research, August 2011 Reservoir. Given the early stage nature of this play, reservoir characteristics for the Duvernay shales are very limited, though the data thus far appears encouraging. Specifically, in the Kaybob region, the Duvernay shales are estimated to have porosities in the 3–12% range with matrix permeabilities between 0.00001–0.01mD. Note that these permeabilities are similar to that of the Eagle Ford shales in Texas, where the oil, wet gas and dry gas windows have all shown to be productive in varying capacities. From a mineralogical point of view, the Duvernay shales are not created equal and are in fact quite variable. At Kaybob, the formation is dominantly quartz and calcite (~50–60%), with a clay content between 15–25%. Elsewhere across the West/East Shale Basin, the mineralogy ranges between 1–47wt% quartz, 18–90wt% carbonate, and 3–37wt% clay (see Figs 5, 17 and 18). We would consider a quartz/carbonate (calcite) content greater than 40wt% combined with a clay content less than 30wt% to be the desired mineralogical properties for an effective shale oil/gas reservoir. Note that the higher the silica/carbonate content, the more brittle the rock, which is one indicator of the ability for induced fractures to propagate in the reservoir. Based on the composition data for other shale gas plays in the US (see Fig 6), we would surmise that the Duvernay locally has mineralogical properties similar to the Lower Marcellus, Haynesville and Eagle Ford. We note that this comparison is fairly loose given the data presented in Fig 6 is calculated as a percent volume, while the data in Fig 5 is in percent weight. 15 August 2011 4 Macquarie Research Fig 4 Do the ‘Dew’vernay!

Hall, 2010), ERCB/AGS, Company Reports, Macquarie Research, August 2011 Thermal Maturity/Depth. We present the virtrinite reflectance (Ro) contour lines per the Geological Survey of Canada (GSC) Open File 4341 in Fig 7. As a loose definition, between 0.6–1.0% Ro, the shales are likely in the mature or oil generating window. A Ro between 1.0–1.6% suggests a condensate-wet gas window, while a Ro greater than 1.6% typically indicates the shale unit is generating dry gas (ie, Horn River Basin >2.0% Ro). Below 0.6% Ro, the shales are likely in the immature window, suggesting insufficient thermal alteration to have generated hydrocarbons. Immature shales can be damaged by drilling fluids and are often more ductile (less consolidated or softer, generally not ideal for fracture treatments) because of the particular type of clay contained within (ie, swelling or smectite clay). Note that the maturation distributions per the GSC are fairly broad and actual micro-maturity characteristics are still to be articulated through future drilling activity. Interestingly, the thermal maturation contours correspond well with the depth of the Duvernay, ie, the deeper the shales, the higher the degree of thermal alteration. In the Wild River-Kaybob area, for instance, the depth of the targeted shale ranges from 3,200–3,800m. Heading north towards Sturgeon Lake, we note the depth of the shales is shallower at 2,500–3,000m, which suggests lower pressure and degree of alteration. In the greater Pembina region, the depth of the Duvernay ranges between 2,500–4,000m. Overpressured = more storage. The Duvernay interval is also normal-to-overpressured, depending on the location (normal pressure is ~0.43psi/ft). A higher pressure gradient or overpressured region generally translates into higher potential Original Gas in Place (OGIP) and well deliverability, all else being equal. At Kaybob/Fir, for instance, the pressure gradient is over 2.0x normal (~0.83–0.96psi/ft). Heading north towards Ante Creek, we note that the gradient drops precipitously to 0.53psi/ft (23% overpressured) and then falls to a normally-tounderpressured regime (~0.41psi/ft) at Sturgeon Lake. In the greater Pembina region, we have one legacy well indicating a slightly overpressured regime (~10% overpressured) in the East Shale Basin, just off the east side of the Rimbey–Meadowbrook Leduc trend Given the lack of hydrodynamic data, we have provided for reference the Deep Basin edge in Fig 7. In general, the Deep Basin can be broadly described as a region (typically Cretaceous packages only) where regionally pressured water is characteristically found structurally updip of underpressured gas. 15 August 2011 6 15 August 2011 Duvernay geological map – Rho, Depth, and Thickness Source: GSC Open File 4341, geoSCOUT, Macquarie Research, August 2011 Fig 7 Macquarie Research Do the ‘Dew’vernay! 7 Macquarie Research Do the ‘Dew’vernay! Thickness. Gross thickness of the Duvernay typically ranges between 10–70m. In proximity of reef complexes, the Duvernay thickens to nearly 40–70m as a result of reefal ‘skeletal debris’ adding to the coarseness and brittle nature of the package. We believe this is an important concept to remember, as the majority of the recent land sales have been near Leduc Reefs (ie, near the Wild River sub-basin or near the Rimbey–Meadowbrook Trend in the greater Pembina region). Note that away from the reefal complexes, particularly in the West Shale Basin, thicknesses are less than 40m, which implies potentially lower gas or oil in place in comparison to the shales near the Leduc Reefs, all else being equal.

Hall, 2010), Company Reports, Macquarie Research, August 2011 Duvernay sweet spots – How do reservoir parameters impact OGIP? We present a tornado diagram in Fig 9, which summarizes the impact of three key reservoir parameters that would have on OGIP. We have given a range of values for pay, porosity and pressure for the Duvernay interval. The vertical line down the middle visually projects the expected OGIP using the average of all variables. That is, an average thickness of 37.5m, average porosity of 5% and reservoir pressure of 6,600psi results in an expected OGIP per section of 45bcfe. To estimate the impact of changing one of the variables, we hold the two others constant at the average and adjust the parameter to be varied as desired to determine the impact on OGIP. For example, to estimate the impact of a 4% total increase in porosity could have on OGIP, move right from the median line in the porosity row to 9%, which results in OGIP per section of 80bcf, holding all other variables at the average (37.5m pay, 6,600 psi). A 4% porosity (better rock) increase would therefore result in a 77% total increase in OGIP per section. As the tornado chart shows, pay thickness and porosity are the dominant drivers of variability in OGIP. 15 August 2011 8 Macquarie Research Do the ‘Dew’vernay!

Duvernay land sales Over C$1.4bn spent since late 2009 Since late 2009, land sale activity for the Duvernay shales has gone into overdrive, with over C$1.4bn spent to purchase more than 1.0m net acres of land throughout Alberta (mainly by major oil & gas companies). Unit prices since 2009 have averaged C$200–400/acre, with some land in the greater Pembina/Kaybob regions fetching nearly C$5,800/acre. Five of the most notable land sales include: 1. Wild River – 15 December 2009. A total of 263,040 acres of land sold for C$332.9m, amounting to an average price of C$1,266/acre. Some parcels sold for as high as ~C$2,154/acre. Note that this was the first land sale that arguably put the ‘Duvernay shales’ into the spotlight. 2. Kaybob/Fox Creek – 7 July 2010. A total of 125,440 acres of land sold for C$336.7m, which translated into an average price of C$2,685/acre. The maximum price paid was C$4,174/acre. We believe both Encana and Chevron participated in this sale. 3. South Pembina/Willesden Green – 15 December 2010. A total of ~141,000 acres of land sold for C$145m or C$1,015/acre solidifying what we view as the continuation of the Duvernay into the most southeast extremities of the play. 4. Willesden Green/Pembina/Ferrier – 1 June 2011. In the largest sale to-date in Alberta, a total of ~360,000 acres in the Willesden Green/Pembina/Ferrier areas went for a mighty bonus figure of C$753m, translating into an average price paid of C$2,065/acre. Notably, a land broker paid nearly C$5,800/acre for a parcel of land in the Willesden Green region. 5. Edson – 27 July 2011. This land sale saw 79,230 net acres going for C$57m for Duvernay land at Edson, amounting to an average price of ~C$719/acre. The high metric of C$2,700/acre was similar to the prices paid in the Wild River/Kaybob/Pembina regions during previous sales. More Duvernay land up for sale? We believe there remain two additional land sales postings, one on 24 August 2011 and the other on 21 September 2011, that are of particular interest. On 24 August, we estimate a total of 11–12 townships of land are up for sale in the Fox Creek/Sturgeon Lake areas in what we believe is the oil window of the Duvernay shales (see Fig 10). On 21 September, approximately 6–7 townships are up for grabs in the Ferrier region, which are nicely situated in the liquids rich gas window of the play (see Fig 12). 15 August 2011 10 Macquarie Research Fig 10 Do the ‘Dew’vernay!

Meet the players Because of the expansive nature of the Duvernay shales, we believe there will be plenty of open Crown land opportunities (as noted previously) for newer entrants to establish an initial position. That said, the first movers have likely acquired what we deemed as the ‘sweet spots’ of the play. Because of the high capital intensity (ie, >C$10m DC&T costs), we also believe there will be a number of producers that may look to sell or farm-out their land positions, similar to what Orleans and Argosy did with their deep rights at Kaybob and Ante Creek, respectively. Based on publicly available data, we charted those producers with meaningful Duvernay positions, as shown in Fig 14. The data provided herein are based on geoSCOUT data, publicly announced positions, or those disclosed by management. As can be seen, Athabasca (ATH CN) has the largest Duvernay position within in our study group, followed by Encana (ECA US), Talisman (TLM CN), Chevron (CVX US), Trilogy (TET CN) and Daylight (DAY CN). Other mid-cap producers with meaningful positions include Celtic (CLT CN), Angle (NGL CN), Bellatrix (BXE CN), Vero (VRO CN), Galleon (GO CN), and Chinook (CKE CN). Among the Junior E&Ps within our coverage universe, Delphi (DEE CN) has a respectable position. In the Private E&P space, we note that TAQA, B&G, Northern Patriot, PetroSpirit and Arriva all hold Duvernay acreage.

Duvernay activity Activity in the Duvernay shales has largely been a science experiment to this point, with only a handful of wells recently drilled into the play. In total, we count around 24 wells that have been licensed or drilled to-date, consisting of 15 vertical delineation/test wells and 9 horizontals. The two most notable are Celtic, Trilogy and Yoho’s horizontals (33.3% W.I. each) at Kaybob. The first horizontal tested at 2.1mmcf/d of sweet natural gas and ~75bbl/mmcf of NGLs and condensate, with only 6 of the 13 planned stages frac’d because of a rupture in the liner, while the second horizontal tested at 5.2mmcf/d plus 390bbl/d of liquids. Of the 24 wells drilled or licensed, there are 2 verticals (Yoho and Arriva) and 2 horizontals (ConocoPhillips) licensed in the greater Pembina region. For the remainder this year and throughout 2012, another 20+ vertical/horizontal wells are expected to be drilled. Notable players that have indicated Duvernay programs include Encana at 2 wells, Talisman at 2–4 wells, Chevron at 5–10 wells, Daylight at 4 wells, and Husky at 2 wells. In addition, Celtic/Trilogy/Yoho, Birchcliff, PetroBakken, Sonde, Bellatrix, Bonavista and Longview each plan to drill at least one pilot well in 4Q11 or 1Q12 to help appraise the prospectively of the play. Based on the activity maps in Figs 17 and 18, we highlight the following six legacy wells that have tested oil/gas from the Duvernay: Legacy wells. As background, there have been numerous wells penetrated through the Duvernay, mostly targeting the Leduc Reefs or Beaverhill Lake trends across the Kaybob/Pembina region, giving producers plenty of log and core data through the area. Of the 50,000+ wells that have penetrated the Duvernay, we highlight the following six legacy wells: 07-30-58-22W5 (Duvernay Oil) – tested 441mcf/d of gas from the Duvernay, with a calculated pressure gradient of 0.96psi/ft (+120% overpressured). 14-23-67-24W5 (Murphy Oil) – recovered 562bbl of 39.4°API oil, with a calculated pressure gradient of 0.53psi/ft (22% overpressured). 05-02-67-26W5 (Forest Oil) – recovered 3,693bbl of oil, with a calculated pressure gradient of 0.44psi/ft (normally pressured). 06-07-38-27W4 (Kanata) – recovered 1,146m and 304.8m of oil from two DSTs. Gas and oil to surface from DST #1 were measured at 236mcf/d and 32bbl/d, respectively. The calculated pressure gradient was 0.48psi/ft (10% overpressured). 16-35-40-03W5 (Texaco) – recovered 634bbl of Duvernay oil. 06-10-38-09W5 (Canadian Hunter) – tested 35mcf/d of Duvernay gas. Recent wells. Based on public data (as of 30 June), Celtic et al.’s first horizontal located at 15-33-60-20W5 has cumulatively recovered ~128mmcf of gas and 761bbl of condensate. The second horizontal, which was operated by Trilogy, is located at 03-13-60-20W5 and has recovered ~134mmcf of gas and 9,785bbl of condensate. More recently, Trilogy and Celtic noted associated liquids production in the 90-100bbl/mmcf (~63% condensate) range in both horizontals. Of the vertical wells drilled so far, Encana noted its first well into the play (11-08-62-24W5) yielded liquids in the +75bbl/mmcf range. Lastly, there is one well drilled by Xerex Energy at 07-22-69-21W5 in the Sturgeon Lake area that cored/logged the ‘oily window’ of the Duvernay formation. We believe the technical information from this well could be of interest for players in the Sturgeon Lake area (ie, Delphi, Longview and Athabasca). What to look for – upcoming wells. Chevron’s 08-15-62-18W5 horizontal licence will be a key well to watch, as it is located in the ‘oilier’ portion of the play. This could be a catalyst for producers with lands outside the liquids rich window (ie, Trilogy, Athabasca, Argosy, Longview, Delphi, etc.).

Specifically, ConocoPhillips has two upcoming horizontals licensed there. 15 August 2011 18 Macquarie Research Fig 17 Do the ‘Dew’vernay!

Case study: Eagle Ford shales Though production data is limited in the Duvernay, industry players generally believe this play will have highly variable liquids content, depending where the acreage is situated. A recent case study of a shale gas play with this characteristic is the Eagle Ford of south Texas. This play is about two years ahead of the Duvernay in terms of its development, and with several well penetrations, industry has been able to map the dry gas and liquids rich portions of the play (Fig 19). The Eagle Ford trends southwest to northeast. Lands on the southern portion of the trend are generally dry with no associated condensate or NGLs. The northern regions become much more oily, with gas a much smaller fraction of the overall production mix. The downside is the high relative viscosity of the oil can reduce recoverable reserves. The sweet spot of the play seems to be the condensate/gas window that runs in the middle, where the lower viscosity liquids combined with high gas content see very high recoveries. Fig 19 Eagle Ford liquids content Source: US EIA, Macquarie Research, August 2011 This variation in liquids content is clearly evident in Fig 20. The oil to gas ratio (OGR) ranges from 0bbl/mmcf (dry gas) in the southeast to nearly 300bbl/mmcf in the northwest. Initial results from the Duvernay have delivered OGR’s of ~70-100bbl/mmcf, which would put it just below the average of the Eagle Ford. However, we see potential for much higher liquids yields as more wells are drilled to define the liquids rich sweet spot of the play. 15 August 2011 21 Macquarie Research Do the ‘Dew’vernay! Fig 20 Eagle Ford liquids content cross section Source: Pioneer Resources, Macquarie Research, August 2011 Rock characteristics and depth similar The overall depositional setting and reservoir characteristics are quite comparable between the Eagle Ford and the Duvernay (Fig 21). The depth to the Duvernay and Eagle Ford is nearly identical, and we expect lateral horizontal length to also end up similarly. Gross reservoir pay is also consistent, though the Duvernay is lower in comparison. Eagle Ford drill/case/completion costs are running between US$8–10m per well. Given the early stage of the Duvernay, there is limited data, with only Trilogy’s well at Kaybob having reported costs as high as C$17m. We do not view this as representative as there were drilling issues with this horizontal. We expect costs for the Duvernay to approach those in the Eagle Ford given their similar depths (both True Vertical Depth and Measured Depth).

Going deep. At depths of over 3,000m, both plays are at the deeper end of the range for wells drilled onshore in North America. Hence, given the relatively high costs associated with the play, we ultimately expect the Duvernay to be dominated by larger players with deep pockets. Under pressure. Both the Duvernay and Eagle Ford are overpressured; that is, the reservoir pressure is higher than projected based on depth. This is important for two reasons: 1) the storage capacity of the rock is higher at higher pressures (for gas); and 2) the deliverability is higher as there is more potential energy under gas drive where the force of the gas expanding is what results in higher production rates. ‘Frac-ability’ expected to be similar. The silica and carbonate contents of both reservoirs are similar. The higher the silica content, the more brittle the rock, which is one indicator of the ability for induced fractures to propagate in the reservoir. Comparatively, rock with a higher clay content is more ductile and resilient to fracturing. We see that the Duvernay certainly meets the criteria for multi-stage fracturing, depending on the location. Comparable resource density. The volume of resource in place is highly variable in the Eagle Ford, and there is nearly a linear relationship with thickness. More rock results in more resource. The same is true for the Duvernay. We estimate the thicker portions of the Duvernay should hold similar resource in place as the Eagle Ford. The challenge will be to figure out the optimal completion method to maximize recovery factors. As more wells are drilled, we will also get more insight into how much of the resource in place is liquids or oil versus dry natural gas. Completion methods: Optimizing costs and recoverable reserves Duvernay completions. With only two horizontals down into the Duvernay, there has not been a convergence towards a preferred completion method for the play. Production rates and EUR’s are highly contingent on the type of frac fluid, size of fracs, proppants and number of fracs per horizontal section. Celtic/Trilogy/Yoho. The group’s first well was completed using a ‘Packers Plus’ assembly. Despite only six stages of the planned thirteen being completed due to rupture in the liner, Celtic et al. pumped ~100 tonnes of sand into each stage combined with 1,500m3 of slick water. The group’s second Duvernay horizontal was completed using a staged ‘plug and perf’ horizontal completion technique, which incorporated perforation clusters (2–3 per stage) to stimulate the well. In total, Trilogy et al. pumped a total of 2,300 tonnes of sand along with 138,600bbl of slick water into 12 stages. Based on the results of these two horizontals, we understand the group may try a ‘hybrid’ fluid of slick water and cross linked gels, which may improve productivity. Eagle Ford completions. On our thesis that the Eagle Ford represents the most direct comparison to the Duvernay, we summarize what some of the key players have discovered regarding completions and well performance on that play. Pioneer Resources (PXD US). One of the most active Eagle Ford shale players, Pioneer has moved from using slick water fracs, to what it calls a ‘hybrid’ fluid of slick water and cross-linked gels. Most wells have 14–18 stages, with 300,000lbs of sand placed in each stage. The first 50,000lbs of sand is typically 100 mesh sand, with the remainder a light weight ceramic. Total proppant placed can be well above 4m lbs per well. It is believed that the cross linked gels are better able to carry more sand deeper into the formation. As the Eagle Ford is deeper than most shale plays, the reservoir temperature is higher, facilitating the breakdown of the gels in the reservoir, with no noticeable impact on production. Production results clearly exhibit similar initial production rates, though at a much lower decline rate than with slick water alone. 15 August 2011 23 Macquarie Research Do the ‘Dew’vernay! Fig 22 Pioneer Eagle Ford completion comparison Source: Pioneer Resources, Macquarie Research, August 2011 Petrohawk (HK US). Petrohawk was recently acquired by BHP, and arguably the crown jewel within Petrohawk’s portfolio is its Eagle Ford position. Similar to Pioneer, Petrohawk was evaluating a combination of slick water and gel. In addition, the company was evaluating a number of other variables to determine the impact on productivity. Some factors include length of the horizontal lateral, number of perforations per stage, ceramic versus sand and the optimum concentration of sand per stage. Aurora Oil and Gas (AEF CN). Aurora’s operating partner, Hilcorp (recently acquired by Marathon), has moved to utilizing Schlumberger’s HiWAY frac process. This process aims to increase fracture conductivity, facilitating the movement of hydrocarbons in the fracture to a greater degree than conventional frac jobs. The proppant is placed in pulses, interspersed with carrying fluid (slick water), while perforations are placed to enhance the formation of channels. The intent is to ensure that the proppant is placed in all perfs, not just one set.

Duvernay economics Liquids abound In the current gas price environment, producers are seeking exposure to liquids-rich projects that can enhance the revenue stream. An important element supporting Duvernay economics is the associated liquids yield. The first two horizontals into the plays have tested over 75bbl/mmcf of NGLs (the second horizontal tested 390bbl/d of NGLs, including 180bbl/d of 56° API condensate). More recently, Trilogy, Celtic, and Yoho have noted liquids yield closer to 90–100bbl/mmcf of NGLs from their first two horizontals. While initial results are encouraging, further production data is required to ascertain whether the well can continue generating liquids at this level. Type curves. We introduce four horizontal type well curves and economics in the following figures. Given the lack of publicly available production data, we have placed increasing importance on input sensitivities, namely, in the liquids yield, EURs and capital costs. Our type well assumptions will evolve with further delineation of the play by industry participants. We assume a consistent IP rate of 4.2mmcf/d of natural gas in our four type well curves that vary by liquids content: 50bbl/mmcf, 75bbl/mmcf, 100bbl/mmcf and 150bbl/mmcf. Our EUR assumptions range from 725mboe/well to 1,055mboe/well. The majority of the recent well licences have been within the liquids-rich gas portion of the fairway as wells targeting the dry gas window to the west would otherwise be uneconomic in the current gas price environment. We do not have any data on the potential recoveries in the oil window.

It is important to highlight that our four Duvernay cases assume increasing EURs with liquids yield. This assumption is likely flawed, in our view, given a higher oil-to-gas ratio generally translates into a lower gas drive (ie, less energy in the reservoir to push the liquids out), more viscous liquids, and lower relative permeability, which would result in lower ultimate recoveries or EURs, all else being equal. That said, we have left our EUR assumptions unchanged, as noted previously, pending more production data. Type well economics. Our 75bbl/mmcf type well (base case) generates a before tax NPV of C$8.7m and profit-investment ratio of 0.8x with IRR of 46%. Assuming a drill, complete and tie-in cost of C$11m, the well is expected to recover 805mboe/well. The before tax break-even supply cost for this well is estimated at US$3.79/mmbtu. Our economics are based on our long-term price deck assumptions of US$90/bbl WTI, US$6.00/mmbtu Henry Hub and US$0.95 Canadian dollar. Pricing. The realized NGL plus condensate pricing varies with the components in the liquids stream (eg, condensate, pentane, butane, ethane, etc.), and will depend on the producer’s ability to extract these higher valued liquids through deep cut facilities. We have assumed a 20% differential to the WTI oil price for the NGL stream (ie, 60% condensate/40% NGL mix). Royalties. The Alberta royalty framework offers attractive incentives to promote unconventional shale gas drilling activity. Horizontal shale gas wells are subject to a 5% royalty rate for a maximum of 36 months, with no volume cap. Also, gas wells drilled to true vertical depths (TVD) greater than 2,000m qualify for the Natural Gas Deep Drilling Program (NGDDP). At TVD of 3,200–3,800m in the Kaybob region, Duvernay shale wells meet the criteria and allow producers to claim this royalty benefit. Royalty rates for NGLs range between 35–40% depending on the liquids composition. 15 August 2011 26 Macquarie Research Do the ‘Dew’vernay! Well costs. Our cost assumptions are on a half-cycle basis, including drilling, completion and tie-in well costs and excluding upfront expenditures for land and facilities. At Kaybob, we forecast drill, complete and tie-in costs of C$11m, consisting of horizontal drilling costs of C$4.2m and completion costs of C$6.0m. Note that the completion costs will be highly dependent on the technology used, number of frac stages, size of fracs (tonnes) and types of frac fluid and proppant (sand was used in the first two horizontal wells). Once producers have transitioned the play into development, multiple-leg and pad drilling could improve total costs. As background, the price tag for the first Duvernay horizontal well came-in at C$4m to drill and case over a period of 42 days, with only 6 of 13 stages frac’d. Excluding the rupture in the liner, Celtic believed a drill and complete cost of C$7–8m would have been reasonable. The second horizontal was drilled over 50 days for C$6.5m and was completed using the ‘perf-and-plug’ method with slick water fracs at a cost of C$11m, totalling C$17.5m. Acknowledging that this latest well is not economic at such a high cost and current gas prices, we are not quick to dismiss the Duvernay play based on the initial results of these first wells. These are designated ‘science wells’ and we believe capital efficiencies should improve with time when the optimal drilling and fracturing design is achieved. In comparison. Celtic, Trilogy and Yoho’s well assumptions range between 4.1–4.7mmcf/d for IP30 rates, 5.0–5.6bcfe/well EUR, 70–75bbl/mmcf of NGLs and C$10–12m/well for an all-in capital costs (drill, complete and tie-in). Development scenario. Note that the resource in place in the Kaybob region, specifically for the liquids rich gas window, is estimated between 100–150bcf per section. Using our 4.8bcfe/well EUR (base case) and a well density of 5–8 wells per section, this would result in a recovery factor of ~20–25%. For the oil and gas windows of the Duvernay, we believe the ultimate well density or recovery factor will be highly dependent on some of the key geological factors noted earlier in the report (ie, thickness, porosity, pressure, water saturation, etc.). Economic sensitivities. The Duvernay is still a play in its infancy and will show variability in initial rates, recoveries and costs. In Figs 26–29, we show NPV sensitivities to commodity prices, liquids yield and capital costs. Unless noted, our economic sensitivities assume a constant oil:gas price ratio of 15:1 (eg, US$90/bbl WTI and US$6.00/mmbtu Henry Hub). Overall, we believe a 50bbl/mmcf liquids yield is the minimum amount necessary to achieve a 20% AT IRR.

Infrastructure Though it may be premature to discuss infrastructure needs for an early stage resource like the Duvernay, we feel it is important to highlight some of the major processing facilities in the both the Kaybob and Pembina regions. Given the Duvernay stretches across most of the Alberta Deep Basin, gas gathering lines, compressor stations, and gas facilities are already well established/developed. In addition, the gas content from some of the early Duvernay wells is essentially sweet, so no sour gas processing is required. In both the Greater Kaybob and Pembina regions, we have provided a map of the major gathering lines/facilities in Figs 32 and 33. Note that we have shown only gas plants with processing capacities greater than 100mmcf/d. Deep vs. shallow cut. With the Duvernay being potentially a sizable liquids rich gas play, we believe producers will be looking to process their raw gas streams through ‘deep cut’ facilities, rather than the standard ‘shallow cut’ or general field plants. ‘Deep cut’ refers to plants that are capable of separating nearly 100% of the propane, butane, pentanes/condensate and +60% of the ethane from a typical gas stream. Segregation of these constituents provides producers with higher revenue/netbacks, all else being equal, and accordingly, better per well economics. ‘Shallow cut’ plants typically only recover 100% of the butane and pentane/condensate, but less than 60% of the propane and none of the ethane. Our view is that producers will ultimately move their raw gas stream to ‘deep-cut’ style facilities, either through their own or third-party expansions, in order to realize the best economic return from their Duvernay wells. 15 August 2011 30 Macquarie Research Fig 32 Do the ‘Dew’vernay!

Valuation and conclusion Do the ‘Dew’vernay! The use of horizontal multi-frac technology along with a greater technical understanding of shales has no doubt opened up a number of additional resource plays across North America. The Duvernay shales are a perfect example of a newer resource play that with a significant amount of science, a lower cost structure, and a little luck, could emerge as one of the biggest resources to hit Western Canada since the Montney. With 24 wells drilled or licensed so far, with another +20 planned for 2011/2012, we expect upcoming well results to be important data points for producers with Duvernay exposure. Further down the road, if the ‘hype’ lives up, we anticipate heightened acquisition activity, especially for those looking to consolidate their positions. Acre/EV. Because it is still early days for the Duvernay, we have limited the use of risked upside for generating a comparative valuation. Instead, to measure Duvernay leverage, we have created an Acre/EV comparison, as shown in Fig 34. We note that measuring leverage based on an Acre/EV metric has limitations, as not all producers are Duvernay pure-plays and the metric is often skewed by production and other assets both domestically and internationally.

In other words, if a producer’s Duvernay position accounts for a large portion of its total undeveloped acreage, then the company is more leveraged to the play for every dollar of enterprise value. 15 August 2011 33 Macquarie Research Do the ‘Dew’vernay!

Within our coverage universe, Talisman Energy (TLM CN) shows up as the most leveraged Large Cap producer followed by Encana (ECA US). Among our high yield/mid cap producers, we believe Athabasca (ATH CN), Daylight (DAY CN), Celtic (CLT CN), Chinook (CKE CN), Bellatrix (BXE CN), Vero (VRO CN) and Angle Energy (NGL CN) have the best exposure to the play. On the smaller cap side, Delphi (DEE CN) has the highest leverage relative to its size, though we note its lands are located in the more unproven ‘oil window’ of the play. Outside our coverage universe, we highlight Trilogy (TET CN), Mako Energy (MKE AU), Kilgore (KOG AU), Sonde Resources (SOQ CN), Longview (LNV CN), Galleon (GO CN), Yoho (YO CN) and Terra (TT CN). Balancing the high capital intensity of the play, quality of the assets, leverage, and upcoming catalysts, our top picks are Talisman (TLM CN), Encana (ECA US), Celtic (CLT CN), Daylight (DAY CN), Angle (NGL CN) and Athabasca (ATH CN). 15 August 2011 34 Macquarie Research Do the ‘Dew’vernay!

Duvernay producers – Summary of net sections Angle (NGL CN; C$8.15); Rating: Outperform; Target: C$11.50 Net Sections: 110 Angle holds 110 net sections of Duvernay rights in Edson (45 net sections) and the greater Kaybob/Ferrier areas. At Edson, the company sees higher porosities (up to 14%) compared to the Duvernay in Kaybob; however, the thickness there is lower (~20–25m), which may translate into a lower OGIP. Note that the company already completed drilling its vertical well at 04-36-5217W5 (Edson). Argosy (GSY CN; C$2.57); Not Rated Net Sections: 6 Argosy holds an 82% working interest in 7.5 gross sections of Duvernay prospective land at Ante Creek. Currently, there are no plans to either drill or test the Duvernay formation; however, the company may look to farm-out opportunities to larger players with deeper pockets. Arriva (Private); Not Rated Net Sections: 5 Arriva’s total land position is unknown; however, based on geoSCOUT, we estimate the company holds 5 net sections in the Greater Pembina fairway. The company has licensed its first vertical Duvernay well at 01-06-038-07W5. Athabasca (ATH CN; C$13.32); Rating: Outperform; Target: C$20.00 Net Sections: 742 Since purchasing 1.0m acres of land in the Deep Basin in late 2009 through 2010, the company now holds 475,000 net acres prospective for the Duvernay formation. Note that most of these lands were acquired at an attractive price of ~C$100/acre, which is well below the prices paid in recent land sales. In our view, the majority of Athabasca’s lands fall within the oil/liquids rich gas window of the Duvernay. In terms of activity, Athabasca has drilled a vertical well in Saxon (102-10-09-62-23W5). 15 August 2011 36 Macquarie Research Do the ‘Dew’vernay! B&G (Private); Not Rated Net Sections: 73 Bellatrix (BXE CN; C$4.15); Rating: Outperform; Target: C$6.25 Net Sections: 46 Bellatrix holds 46 net sections of Duvernay rights west of the Willesden Green area on First Nation's Land. The company has indicated it may look to lengthen an existing vertical well and then take the well horizontal. Drilling plans are tentatively scheduled for 1H12. Birchcliff (BIR CN; C$13.10); Rating: Neutral; Target: C$12.00 Net Sections: 50 Based on geoSCOUT, we estimate Birchcliff holds over 50 net sections of Duvernay acreage, all located in the oil/liquids rich gas window of the play. It plans to drill a vertical exploration test into the Duvernay sometime in late 2011. Bonavista (BNP CN; C$25.91); Restricted Net Sections: 75 Bonavista announced that it holds ~75 net sections of Duvernay rights in the condensate window. The majority of these lands were acquired through the company's 2009 acquisition of the Hoadley property from Encana. 15 August 2011 37 Macquarie Research Do the ‘Dew’vernay! Celtic (CLT CN; C$21.18); Rating: Outperform; Target: C$29.00 Net Sections: 145 Celtic Exploration has participated in a total of five Duvernay vertical tests and two horizontals. Its first operated horizontal (33.3% W.I.) that was partnered with Yoho and Trilogy at 15-33-60-20W5 was drilled and completed in the summer of 2010. That well produced 2.1mmcf/d and 75bbl/mmcf of 56°API condensate from only six of the planned 13 stages because of a rupture in the liner. The well is currently yielding 100bbl/mmcf of NGL’s since April, comprised of 63% condensate, 15% butane and 22% propane. Along with its partners, Celtic plans to drill another horizontal in 2H11 (33.3% WI). Celtic holds 145 net sections of deep rights, of which they believe 100 net sections will ultimately be prospective for the Duvernay. Cequence (CQE CN; C$3.80); Rating: Outperform; Target: C$4.25 Net Sections: 11 Chevron (CVX US; US$94.07); Rating: Outperform; Target: US$117.00 Net Sections: 313 Chevron holds nearly 200,000 net acres of land targeting the Duvernay shales. Its first horizontal is licensed at 04-21-059-19W5 (Kaybob), while its second horizontal is licensed at 06-22-062-18W5 (Fox Creek). We believe the second license represents a key well for Chevron and the entire Duvernay play, as it will be testing the so-called ‘oil window.’ To our knowledge, Chevron intends to be one of the most active producers in the area, with plans to drill up to 10 wells over the next twelve months. Based on the recent licenses, we can surmise that Chevron participated in both the 15 Dec 2009 and 7 July 2010 land sales. Chinook (CKE CN; C$1.83); Rating: Outperform; Target: C$3.50 Net Sections: 68 15 August 2011 38 Macquarie Research Do the ‘Dew’vernay! Connacher (CLL CN; C$0.74); Rating: Outperform; Target: C$1.75 Net Sections: 28 ConocoPhilips (COP US; US$65.52); Rating: Neutral; Target: US$74.00 Net Sections: 135 Conoco has licensed two Duvernay horizontals in the Willesden Green area in what appears to be the liquidsrich gas/oil window of the play. We also understand that in the coming months, Conoco is set to license another horizontal Duvernay well in the area. Crew (CR CN; C$12.58); Rating: Outperform; Target: C$23.00 Net Sections: 23 Crew has no imminent plans to drill a Duvernay well, but is monitoring activity. Daylight (DAY CN; C$7.76); Rating: Neutral; Target: C$9.75 Net Sections: 203 During 2011, Daylight has expended ~C$100m at Crown land sales, primarily focused on the Duvernay shale. In total, Daylight controls over 130,000 net acres of Duvernay rights in Alberta, which it believes are prospective for oil and liquids rich natural gas. Daylight plans to initiate a four well pilot project in Q1 2012, with an initial three wells planned in Pembina and one in the Kaybob area. 15 August 2011 39 Macquarie Research Do the ‘Dew’vernay! Delphi (DEE CN; C$2.30); Rating: Outperform; Target: C$2.75 Net Sections: 79 Delphi acquired approximately 52,200 net acres (79 sections) in the Sturgeon Lake area in 1H10. Initial plans are to complete a reservoir study including an analysis of the cores, fluid type, and other key reservoir characteristics before selecting a drilling location in 2012. Based on its preliminary technical data, the company estimates the thickness of the Duvernay to be 16–32m (average 25m), with average mineralogical quartz plus carbonate content of 72wt% and clay content of 20wt%. Encana (ECA US; US$26.00); Rating: Neutral; Target: US$35.00 Net Sections: 570 Encana has been fairly quiet on their Duvernay ambitions up until recently. In late 2010, the company drilled a vertical delineation well in order to gather the necessary core/technical data. Plans for 2H11 will be to drill at least 2 wells. Altogether, the company holds nearly 365,000 net acres at Simonette, Kaybob, and Pembina – one of the largest land positions in our group. We believe that Encana must have been active at recent Duvernay land sales as most of their disclosed land position does not show up within the public realm. Enerplus (ERF CN; C$28.52); Rating: Outperform; Target: C$32.75 Net Sections: 59 Galleon (GO CN; C$2.81); Not Rated Net Sections: 137 Galleon is one of the first producers to test the Duvernay shales, re-entering and fracing (19 ton frac) an existing well in the Puskwa region back in early 2010. Nothing much was revealed other than the presence of gas. Separately, based on well logs, the company sees up to ~32m of net Duvernay pay with porosity greater than 3% on a Limestone density scale. We estimate that Galleon holds 137 net sections of Duvernay rights in the greater Peace River Arch, likely all in the oil widow and normally-to-underpressured portion of the play. 15 August 2011 40 Macquarie Research Do the ‘Dew’vernay! Husky (HSE CN; C$25.75); Rating: Neutral; Target: C$30.00 Net Sections: 31 In the second quarter, Husky drilled, cored and logged a well at Kaybob to evaluate the Duvernay liquids-rich gas play. Based on the result of this well, the company plans to drill an offsetting horizontal well in 3Q11 to establish the productive capability of this zone. A second vertical test well is also planned for the third quarter to evaluate the play on other existing landholdings. Overall, Husky’s position is considerably smaller than other large cap players like Encana, Talisman, and Chevron. Longview (LNV CN; C$10.60); Not Rated Net Sections: 123 Adjacent to Delphi, Longview holds ~123 net sections of undeveloped land in the ‘oil window’ of the Duvernay shales. The company has no immediate plans to drill a horizontal well; however, it is looking to core the Duvernay at Sunset. After coring operations, the company plans to convert the well to a water injector as part of its plans to optimize the Montney waterflood at Sunset. Mako (MKE AU; A$0.12) Not Rated Transerv (TSV AU; A0.33) Not Rated Kilgore (KOG AU; A$0.002) Not Rated Net Sections: 123 NAL (NAE CN; C$9.95); Rating: Neutral; Target: C$12.00 Net Sections: 170 15 August 2011 41 Macquarie Research Do the ‘Dew’vernay! Northern Patriot (Private); Not Rated Net Sections: 60 Northern Patriot holds 60 net sections of Duvernay rights in the East Shale Basin all situated in the oil window of the play. Interestingly, its lands are adjacent to the 06-07-38-27W4 well that recovered over 1,400m of clean oil from two DSTs in the Duvernay formation. The 06-07 well also has a pressure gradient calculated at 0.48psi/ft, which is 10% overpressured. The company plans to drill its first Duvernay vertical in 4Q11 or early 2012. Penn West (PWT CN; C$19.93); Rating: Outperform; Target: C$26.00 Net Sections: 156 Penn West is one of the largest land holders in Pembina region, driven by its legacy oil assets targeting the prolific Cardium formation. While the company has not yet revealed its land position, we calculate via geoSCOUT that Penn West holds ~100,000 net acres. To our knowledge, there are currently no plans to drill a well here. PetroBakken (PBN CN; C$10.69); Rating: Neutral; Target: C$16.00 Net Sections: 190 Interestingly, PetroBakken holds 190 net undeveloped sections for the emerging Nordegg, Montney, Duvernay, and Swan Hills formation. While the segregation of lands is not detailed, it plans to drill a well into each of these formations by the end of 2011. PetroSpirit (Private); Not Rated Net Sections: 13 15 August 2011 42 Macquarie Research Do the ‘Dew’vernay! Sirius (Private); Not Rated Net Sections: 35 Sonde (SOQ CN; C$2.37); Not Rated Net Sections: 93 Sonde Resources (formerly Canadian Superior) holds 60,000 net acres in the greater Kaybob region, stretching from Windfall, Fox Creek, to as far north as Grand Prairie. As can be seen, Sonde’s lands are all situated in the oil/liquids rich gas window of the play. The company’s 2011 program will involve at least one horizontal exploration well in 2H11. Talisman (TLM CN; C$16.70); Rating: Outperform; Target: C$24.00 Net Sections: 563 On its 2Q11 earnings release, Talisman unveiled it holds 360,000 net acres of Duvernay prospective land at an average cost of C$2,000/acre. We believe a majority of these lands are located in the greater Wild River/Kaybob region. Talisman’s initial plans include having two rigs running over 2H11 to test the Duvernay. Terra (TT CN; C$0.86); Not Rated Net Sections: 50 15 August 2011 43 Macquarie Research Do the ‘Dew’vernay! TAQA (Private); Not Rated Net Sections: 124 TAQA has drilled one Duvernay horizontal at 16-36-61-19W5. We estimate TAQA’s Duvernay position at nearly 124 net sections. Trilogy (TET CN; C$26.35); Not Rated Net Sections: 207 Along with Yoho and Celtic, Trilogy operated the second Duvernay horizontal (33.3% W.I) located at 03-13-60-20W5. The well was drilled early this year, and took 50 days to drill. It tested at 5.2mmcf/d plus 390bbl/d of liquids (including 180bbl/d of condensate). Unfortunately, the total cost for the well came-in at C$17.5m, with the majority of it driven by the completion operations. In total, Trilogy holds a total of 207 net sections. Trilogy also drilled a vertical well at 9-18-64-19W5 to test the oil window of the Duvernay. Note on its 2Q earning release, the company indicated the liquids yield for its 03-13 exploration well appears to be north of 90bbl/mmcf compared with its original yield of 75bbl/mmcf. Trilogy, along with its partners, plans to drill another horizontal well in 2H11 (33.3% WI). Vero (VRO CN; C$4.53); Rating: Outperform; Target: C$7.00 Net Sections: 50 WestFire (WFE CN; C$5.82); Rating: Outperform; Target: C$11.00 Net Sections: 45 15 August 2011 44 Macquarie Research Do the ‘Dew’vernay! Yoho (YO CN; C$3.30); Not Rated Net Sections: 18 Yoho accumulated a total of 17.7 net sections in the heart of the Wild River/Kaybob region. Yoho, along with its partners, plans to drill another horizontal well in 2H11 (33.3% WI). Yoho has also licensed one vertical well targeting the Duvernay formation at 16-24-38-07W5 in the Ferrier area. Note: share prices as at 11 August 2011.
