Horizontal versus Vertical Wells

Production Trends and Potential
5
ND is producing roughly 1 million barrels of oil per day (BOPD)
Production may increase to 1.6 million BOPD Dept. of Mineral Resources projects 10-14 billion
barrels of technically recoverable reserves Industry projections (e.g., Continental Resources) are
much higher—e.g., 20+ billion barrels Continental Resources estimates in-place oil reserves
of 900 billion barrels 60,000 new wells will be drilled over next 20-30 years See following production charts

Critical Highway Transportation Issues
8
Unprecedented heavy truck traffic levels on two-lane rural roads
1st slide following: shows truck ADT projections on oil routes vs. traditional farm-to-market roads
Percent trucks 40% to 50% in many cases Highways deteriorate quickly under heavy loads;
insufficient roadway widths result in narrow shoulders
Truck severe injury crashes in oil region increased by 1200% from 2008 to 2012, vs. 147% increase for remainder of the state over the same period
See trend (2nd slide following) and map of crashes (3rd slide following)

Materials and Product Flows Inputs (e.g., sand, water, chemicals) move to well
site for hydraulic fracturing and production Specialized equipment (drilling and workover rigs)
move to and from well site 1st slide following shows 2,300 drilling-related truck
trips per well Outbound crude initially moves by truck to pipeline
or rail transfer location (2nd slide following); may shift to small diameter pipe later in production cycle
Outbound byproducts: e.g., salt water 12

Currently 69% rail Near-term projection: 90% rail Reasons for rail dominance Limited pipeline capacity (sized to historical
production) Challenges/length of time in siting and
constructing new pipelines Greater ease in capacity expansion of railroads Lower cost of rail expansion Rail access to a wider variety of markets →

Rail Movements
18
Shipments in multicar units or trainloads (e.g., 100+ cars) Current share in ND ≈ 1,000 railcars per day Equivalent to ten 100-car trains/day If railroads maintain 70%+ share, could have 16-20
trainloads per day of crude oil at peak
Questions/potential issues Line capacity: other goods Tankcar standards Transload capacity Accident exposure (train-miles) Service levels and priorities Grade crossings Classification/placarding Risk assessment/routing

Hazmat Concerns
19
Bakken light crude: volatility and precise chemical composition
Disposal of saltwater fracing mix Reduction in flaring: leads to more natural gas
processing (LNG of CNG transport) Fractionation: (NGLs)
Ethane (C2), Propane (C3), and Butane (C4) Grade crossings: increasing truck and train traffic
at traditional low-volume crossings Emergency preparedness and response Pipeline spills Train and truck movements through cities
