The US Geological Survey (USGS) has estimated that the Bakken has a projected mean resource of 3.65 billion barrels of technically recoverable oil, while the Three Forks is estimated to contain 3.73 billion barrels of oil. The two formations were also estimated to contain a mean of 6.7 trillion cubic feet (tcf) of undiscovered, technically recoverable natural gas and 0.53 billion barrels of undiscovered, technically recoverable natural gas liquids (NGLs).

The Bakken Producers

But of most interest to readers will be which companies are going to produce the remaining oil in the Bakken.

Oklahoma City-based Continental Resources (NYSE: CLR) was the first to complete a horizontal well in the Three Forks formation, and to date the company has drilled about 20% of all Three Forks wells. Continental is the largest leaseholder and oil producer in the Bakken with more than 1.1 million acres leased. Continental’s Bakken production totaled 108,573 barrels of oil equivalent (boe) per day in second quarter 2014, an increase of 23% from a year earlier.

The second largest producer in the Bakken is Whiting Petroleum (NYSE: WLL), which averaged 80,195 boe/d in Q2 2014, an increase of 33% in a year. Whiting has a total of 674,162 net acres in the Williston Basin in North Dakota and Montana. Whiting has held the top producer spot in the past, and should soon regain that spot. It recently announced a $6 billion all stock acquisition of Kodiak Oil & Gas (NYSE: KOG), the eighth largest oil producer in the Bakken. The transaction will create the largest Bakken/Three Forks producer, with production of more than 107,000 boe/d in the first quarter of 2014, 855,000 combined net acres and an inventory of 3,460 net future drilling locations.

Bakken oil production is a small part of the overall portfolio of Hess (NYSE: HES), but that’s good enough for third place among Bakken producers. Hess reported 80,000 boe/d of Bakken production in Q2 2014, up 25% over Q2 2013.

EOG Resources (NYSE: EOG) is perhaps best known as the largest oil producer in the Eagle Ford formation in Texas, but the company is also one of the top five oil and gas producers in the Bakken. EOG keeps oil production figures for different production areas pretty close to the vest, but the North Dakota state government does tabulate oil production figures for the companies that produce there. Based on the numbers that were made publicly available (some are listed “Confidential” and unavailable), EOG produced just under 70,000 barrels of oil per day in May 2014. It is possible that if the natural gas EOG produced were included it would rank ahead of Hess in boe/d, but without having all the data available it’s impossible to be certain.

Rounding out the top five for Bakken oil production is Norway’s Statoil (NYSE: STO). Statoil entered the Bakken in 2011 when it acquired Brigham Exploration, a major operator in the Williston Basin. Statoil now holds approximately 330,000 net acres in the Bakken, and in Q2 2014 produced 50,200 boe/d in the Bakken.     

Other major producers in the Bakken include the aforementioned Kodiak Oil and Gas that is merging with Whiting, Marathon Oil (NYSE: MRO), XTO Energy (which was acquired by ExxonMobil (NYSE: XOM)), Oasis Petroleum (NYSE: OAS) — with the exit of Kodiak, the only remaining pure play on the Williston Basin in the top 10 — and Burlington Resources, owned by ConocoPhillips (NYSE: COP).

Risk Factors

Are there any risk factors that could derail this Bakken shale oil boom? There are at least three. One is that oil prices need to remain high in order to keep production growing. The marginal cost of producing crude oil in the Bakken is still in the neighborhood of $100/bbl. A sustained dip to $80/bbl or less would slow the recent production growth rate.

The second risk factor is the possibility that the infrastructure won’t be able to keep up with the growing oil supply. So far the solution to this challenge — in addition to large investments in pipeline infrastructure — has been to use rail cars to move the crude oil out of the area. In just three years the railroads went from essentially zero barrels to 700,000 bpd of crude oil shipped. That is about the volume carried by a fairly large crude oil pipeline. But shipping by rail carries special risks, and recent findings that Bakken oil is more volatile than most crudes are leading to pressure on both the oil industry and the railroads to address this problem.

Finally, a lot of the natural gas that is co-produced with the crude oil is flared. The gas is flared because in many cases there is no cost effective way to get it to market, but this increases the carbon dioxide emissions associated with Bakken oil production. The flaring is so extensive that the Bakken fields glow like a major city at night:

The state of North Dakota recently declared that enough was enough regarding the flaring, and has  ordered companies to find a way to reduce flaring or face mandated production cuts. This will, in turn, likely add to production cost, increasing the risks associated with falling oil prices.

Conclusions

The Bakken Formation was first characterized in the 1950s, and it has produced small volumes of oil for decades. But the marriage of hydraulic fracturing with horizontal drilling led to an oil boom in North Dakota that would rank its oil production ahead of countries like Qatar. Critics of the shale oil boom are right to note that production will eventually slow and decline, but timing is everything. Bakken production isn’t generally forecast to peak until the early part of the next decade, and many companies will benefit. As the easy oil is produced — and presuming oil prices rise — Montana may see its own oil boom, along with the Canadian provinces of Manitoba and Saskatchewan.

Portfolio Updates

No Resting at Oasis

In honor of the Bakken’s round milestone let’s catch up on Oasis Petroleum (NYSE: OAS), which is not only, as mentioned above, the largest remaining pure-play producer in the formation but also our #12 ranked Best Buy.  

The stock touched a new all-time high above $58 in late July, but has since pulled back sharply to $48. The recent dip in crude prices and general energy-sector profit taking certainly played a part, but investors were also less than enthused about the quarterly numbers the company reported on Aug. 5.

The big-picture trend remained strong, with production up 45% year-over-year following last year’s big acreage acquisition and adjusted cash earnings rising 37% as Oasis inches ever closer to cash flow breakeven despite budgeting $1.25 billion for drilling and completions this year,

But those earnings fell a little short of estimates and costs ticked up as Oasis has worked to expand its infrastructure on the new acreage and to work over wells stopped up by the winter cold. Spring road closures also slowed well completions. So while the company’s sticking to its annual production guidance it’s now counting on a stronger second half to deliver it.

But here the big picture is important than the quarterly fluctuations, and the big picture includes far more pad drilling which will serve to drive down costs over the long run, as well as new drilling techniques that are increasing recovery rates at wells they have been tried by as much as 35% relative to the traditional completion methods.

Oasis remains a promising and well-financed producer that is likely to become self-financing soon as it transitions to the more efficient pad production across its acreage and continues to prove the potential of the Three Forks formation beneath the Bakken. The recent pullback in the share price presents an attractive entry point. Buy OAS below $62.
