Bakken Depositional Model:
Prograding Delta: Forced or Normal
Regression?
1.) Unit A deposited in a prograding,
regressive setting
2.) Continued regression and erosion of Unit
‘A’ proximal prodelta deposits, and
deposition of the unit ‘B’ delta-front
sediments.
3.) Unit C deposited in a transgressive
setting

Viking Oil Play
Viking
01/05-33-30-22W3M
694.7m
Complex Geology: Cretaceous fine grained
sandstones and highly bioturbated muddy
sandstones; highly bioturbated; multiple sea
level rises and falls, regressive surfaces of erosion
merging with transgressive surfaces of erosion
Oil Density: 840 KG/m3 (API ~ 36 ) – Light Oil
Production since 1950’s - Oil recovery factors are
low (5-15%), but has a large oil-in-place potential
Production Since 2007 –over 866 horizontal wells
with, multi-stage hydraulic fracturing drilled in
areas of the reservoir where it was thought to
have been depleted through vertical wells

Viking Opportunities
• Proven initial oil-in place:
• 2.3 billion barrels
• Recoverable Reserves based on ‘old school’ technology
(vertical wells and waterflood):
• 214 million barrels (9 per cent)
• Over 2 billion barrels presently unrecoverable
• Shallow target (600-700 metres) of 36° API oil
• Existing infrastructure

Shaunavon Formation
production occurs along a
linear trend (Shaunavon Oil
Field Trend), which extends
from Township 2-18 with
most of the production
centered around Ranges 1820 West of the Third
Meridian
Initially renewed interest
targeted the lower member,
but now a lot of the interest
has shifted back to the
upper member, as well as
the opportunity for multi
zone production (both upper
and lower)
In the last five years ,
horizontal wells in the
Shaunavon have produced
around 12.3 million barrels
of oil, and over 450 wells
were drilled to exploit the
clastic/carbonate upper
member of the formation.
Upper Shaunavon Oil Play
The Shaunavon:
Isopach Upper Shaunavon
Mixed siliciclastic-carbonate
reservoir – shallow marine
(coquina), and clastic channel
deposits
To the end of 2011, there
have been 2,748 wells drilled
into and at some time
produced from the
Shaunavon. Total production
is around 387 million barrels
of 22 API oil.
Production as of May 2011 is
approximately 375 million
barrels (59.6x106m3),
accounting for 99% of the
production from the
Shaunavon Formation
Typical porosity is 15-25%;
permeability varies from
generally 10md to greater
than a Darcy
Isopach Lower Shaunavon
Carbonate reservoir – oolitic &
fossiliferous shoals found in
upper few metres – porosity is
vuggy to mouldic
Porosity ranges from 15-28%;
permeabilities from core
analysis range from generally
less than a millidarcy, but can
be up to 564md
Since 2007, over 210
horizontal wells have been
drilled into the low
permeability reservoirs of the
Lower Shaunavon, with
production totaling over 4.26
million barrels
