Bakken ProjectPhase I – Southeastern Saskatchewan Phase II – North Dakota
Geology, Hydrogeology and Reservoir Characterization
Unconventional Oil?
The Bakken Formation has fast become the hottest onshore oil
play of this decade, revitalizing considerable interest throughout
the Williston Basin. Recent activity in Montana, Manitoba and
now North Dakota and Southeastern Saskatchewan opens a vast
productive fairway. The Middle Bakken siltstones and sandstones are
sandwiched between the best known source rocks in the Williston
Basin. We recognize three distinct petroleum systems-based play
types: overpressured (basin-centered oil), transitional (within mature
source rocks) and migrated. The play holds the promise of 3.6 billion
barrels of technically recoverable oil south of the border1 and 1.3
billion barrels in Southeastern Saskatchewan2. With substantial
variations in facies and reservoir properties, each play type requires
its own technological key to to unlock the resources.

Study ObjectivesCanadian Discovery Ltd., Graham Davies Geological
Consultants and Rakhit Petroleum Consulting are pleased to
announce the first commercially available, integrated multi-
client Bakken study. The main components of the project will
address geology, reservoir distribution, reservoir petrology/
characterization, sedimentology, hydrodynamics and source/
migration issues. The project should allow transposition of
geologic models and data across borders in order to develop
new exploration models and enhance existing ones. Project
objectives include:
� What reservoir characteristics are required for economic
production?
� What roles do sedimentology, diagenesis and pore
networks play? (i.e. for frac design)
� What are the overpressure, transitional and normal
pressure boundaries?
� Are there any effective water bearing zones that can be
fraced into or limit the play extent?
� What is the distribution of the play types?
Phase I – Southeastern Saskatchewan
T. 1-16, R. 1-16W2
Although oil has been produced from the Bakken since 1965,
production has jumped from 200 bbls/d in 2004 to a current
rate of over 30,000 bbls/d and climbing.

Mature Source Rock
Early producers predominantly targeted upper Middle Bakken
dolomitic sandstones with relatively ‘conventional’ reservoir
characteristics (12 to 14% porosity, 0.5 to 5 mD permeability).
Current development, however, is focussing on bypassed, low
resistivity interbedded siltstones of the lower Middle Bakken,
with 10 to 12% porosity and 0.05 to 0.5 mD permeability.
Development of the play is capital intensive, requiring fracture-
stimulated horizontal wells with all in costs reaching $2 million.
Reserves and productivity are improving, with EURs ranging
from 75 to 150 thousand barrels and IPs ranging from 110 to
225 bbls/d. Due to this wide range in potential productivity,
considerable economic uncertainty still exists for the play. The
Bakken Formation, much like most unconventional reservoirs
is vertically and laterally heterogeneous. Expansion of the play
requires an understanding of the variations in stratigraphy,
reservoir characteristics, oil charge and petrophysics.
Phase II – North Dakota T. 141-164N, R. 88-105W
The Bakken play in North Dakota started decades ago as a
fractured shale play at Elkhorn Ranch and on the Nesson
Anticline. The application of fracture-stimulated horizontal well
technology in Mountrail County has resulted in the discovery
of the Parshall Field with initial well productivity reported to be
in excess of 1,000 bbls/d.
At a regional level, North Dakota offers entry into three distinct
Middle Bakken plays: Overpressure, Transitional and Migrated.
The industry’s current focus is within the Overpressure, where
a thick, deep Middle Bakken zone has 4 to 8% porosity and
0.001 to 0.1 mD permeability. Southeastern Saskatchewan
success certainly suggests the migrated oil play works and
has the potential to occur in North Dakota. Expansion of
these plays will require an understanding of the variations in
stratigraphy, reservoir characteristics, oil charge, petrophysics
and hydrodynamics.
