Unconventional Resources of Mexico Opportunities and Challenges CSUR Technical Luncheon September 12, 2012 Presentation Outline Technical Luncheon Presentation Why Mexico The Size of the Prize Unconventional Gas Potential Northern Mexico Basins Burgos Basin Sabinas Basin Tampico Basin Tuxpan Platform Veracruz Basin Natural Gas Market in Mexico PEMEX Plans for Development Mexico Dilemma Challenges Facing Mexico The Final Word September 12. 2012 Why Mexico ? Technical Luncheon Presentation Eagle Ford Fm of the Maverick Basin Northern Basins – gas prone Southern Basins – oil prone Unconventional Resources Geographic Setting September 12. 2012 Technical Luncheon Presentation Why Mexico ? Geology does not stop at the Border Mexico From USGS Geological Map of North America The prospects for unconventional hydrocarbon resources in northeast Mexico are essentially undeveloped yet have very high potential September 12. 2012 Why Mexico ? Technical Luncheon Presentation Eagle Ford Analogue The Eagle Ford Unconventional Resource Play in West Texas in 2011 produced > 40 MM bbls of oil, > 24 MM bbls of Condensate and 290 Bcf of natural gas The Eagle Ford geological equivalent can be found in northern Mexico in the Burgos Basin. While different, the geological equivalent strata are of similar or greater thickness and initial tests has demonstrated gas production September 12. 2012 Why Mexico ? Technical Luncheon Presentation Mexico produced 2.1 Tcf of gas in 2011 but consumed 2.2 Tcf with the differential being supplied by LNG and exports from United States As the country continues to move towards a natural gas powered electrical sector, the differential is expected to increase In the short term it is economically attractive to import gas from the US when North American gas prices are low but this is not sustainable in the long term September 12. 2012 The Size of the Prize Technical Luncheon Presentation Mexico is projected to have the 4th largest resources of unconventional gas worldwide with over 681 Tcf defined (EIA 2011) Increased reliance on natural gas for electrical power generation will increase the domestic demand for natural gas September 12. 2012 Major Unconventional Resources Basin in Mexico Technical Luncheon Presentation Pemex has identified 5 basins that have shale gas potential: Chihuahua Sabinas Burgos Tampico/Misantla Veracruz Pemex has ambitious plans to evaluate and develop the country’s shale gas potential One well, Emergente-1 has been completed and stimulated and an additional 2 more wells are in the planning or early stages of drilling From PEMEX Investor Presentation, 2012 September 12. 2012 Geological Setting and Prospective Basins Technical Luncheon Presentation From EIA website September 12. 2012 Technical Luncheon

September 12. 2012 The Mexico Dilemma Technical Luncheon Presentation The Mexican government and PEMEX recognize the need to explore and develop the unconventional gas potential of the country to meet the growing demands from the electrical sector but there are significant challenges in achieving this goal September 12. 2012 The Mexico Dilemma Technical Luncheon Presentation September 12. 2012 The Mexico Dilemma Technical Luncheon Presentation By law within the Mexican Constitution, only the State can have ownership or hold leases for oil and gas in the country The biggest challenge is to find a mechanism by which foreign companies are incented to invest in Mexico given that they will not be able own or control any of the resources into which they are investing The Mexican government has over the past two years introduced a number of reforms to the oil and gas sector to try and create an environment that will be attractive to foreign investment PEMEX has been instructed to create and award integrated E&P contracts whereby foreign companies will be paid a tariff for each barrel of oil or BOE extracted, plus partial recovery of costs. In addition there are performance based bonuses for improved productivity and cost savings In August PEMEX successfully offered and granted a number of exploration blocks for development, primarily in existing oil prone basins September 12. 2012 The Mexico Dilemma Technical Luncheon Presentation Mexico and PEMEX also recognize that there will be an internal competition for capital within PEMEX In the short term, the focus has been directed towards offsetting the decline of conventional oil production by exploring for new basins offshore as well as employing new technologies on some of the onshore basins where oil production has lagged. This now puts the government in a position to rely heavily on natural gas imports from Texas and LNG to offset the declining natural gas production and the increased demand. This is a “band aid” solution that works temporarily due to low gas prices in the North American market This import solution is not sustainable in the long term as demand increase and projected price recovery will negatively impact the economics of import supply The import solution doe buy Mexico a little time to get their regulatory house in order and allow PEMEX to acquire some preliminary data regarding the unconventional gas potential of the prospective basins September 12. 2012 Mexico Dilemma Mexico currently imports about 1.4 Bcf/day from United States by pipeline , the majority coming from Texas Technical Luncheon Presentation $/mcf Price averaged $4.18/mcf for 2011 but has dropped to less than $3.00/mcf in 2012 Imports of US sourced natural gas are increasing due to low cost and decreasing domestic supply Mmcf/month September 12. 2012 Technical Luncheon Presentation Challenges Facing Mexico Other Challenges that may impact the growth of the unconventional resource industry in Mexico Permitting and Bureaucratic Delays Environmental standards Detail of the fracture Infrastructure Fractured Horizontal Well Vertical well fractured Vertical well High number of personnel and drilling rigs Daily fracturing services Intensive traffic of drilling rigs and heavy equipment Liquids separation plants Safety and Environment Safe operations Wildlife protection and restoration of areas Aquifer protection, recycling water, metal containers, deep latrine wells September 12. 2012 Technical Luncheon Presentation Challenges Facing Mexico Industry is expected to adopt much more rigorous operational and environmental standards than have been the norm in the past all of which add to the F & D cost of any project 34 September 12. 2012 Challenges Facing Mexico Technical Luncheon Presentation State of the art drilling and completion equipment will be necessary to effectively explore and develop the unconventional resource potential – This technology and expertise in most cases, will need to be sourced from outside Mexico September 12. 2012 Challenges Facing Mexico Technical Luncheon Presentation The Cartel has become very adept at utilizing the expansion of the oil and gas activity in the northern border region to assist in the export of their product into United States They have also recognized the value of condensate and have diversified into the “acquisition” and sale of hydrocarbon products on the black market Of course the safety risks of working in the northern border region still exist as the Cartel Zetas have effectively created their own local government September 12. 2012 Challenges Facing Mexico Technical Luncheon Presentation The northeast part of Mexico is very arid and should shale gas development grow at rates necessary to provide the natural gas needed by the country, accessing water for drilling and fracturing operations may be an issue Concerns by local residents in the northern region have already been expressed about water usage and groundwater protection Even though the area is relatively remote, social media attention surrounding hydraulic fracturing will potentially be an issue September 12. 2012 Key Messages Technical Luncheon Presentation Mexico has tremendous potential for onshore unconventional resource development OGIP resource estimates are conservatively placed at 681 Tcf The Eagle Ford Formation of west Texas of the Maverick Basin extends into Mexico into the northern extent of the Burgos Basin providing a reasonable analogue for early stages of exploration and development Early results from PEMEX drilling suggest that shale gas potential is high in the northern Burgos Basin but still in the early stages of knowledge capture Significant exploration capital will be required to effectively explore for these resources PEMEX does not have the capital nor technical expertise to undertake effective exploration and development for unconventional resources including shale gas, tight gas , tight oil and coalbed methane while at the same time developing their conventional oil resources Foreign investment of capital and technology will be necessary for Mexico to achieve their energy goals Current system of resource ownership and leasing is not conducive for foreign investment but the government continues to move towards fundamental changes in the system Safety issues and the presence of the Cartel in the northern border regions will still be a challenge Access to water and groundwater protection will be issues on the horizon should the industry expand dramatically going forward September 12. 2012 Muchas Gracias por su Atención Gracias nuevamente por su apoyo Buenas Tardes y Hasta la Vista Unconventional Resources of Mexico Opportunities and Challenges CSUR Technical Luncheon September 12, 2012
