Dakota oil fields of Saudi-sized reserves make farmers drillers

John Bartelson may look like an average wheat farmer. He isn't. He's one of North Dakota's new oil barons.
Every month, he gets a check for tens of thousands of dollars from a company in Houston called EOG Resources, which drilled two oil wells on his land last year. He says the day his first royalty check arrived was one to remember.
"I smiled to beat hell, and I went to town and had a beer," Bartelson, 65, says. His new wealth springs from the Bakken formation, a sprawling deposit of high-quality crude beneath the durum-wheat fields of North Dakota, Montana and southern Saskatchewan and Manitoba. The Bakken may give the U.S. — the world's biggest importer of oil — a new domestic energy source.
Unlike the tar from Canada's oil sands, Bakken crude needs little refining. Swirl some of it in a Mason jar and it leaves a thin, honey-colored film along the sides. It's light — almost like gasoline — and sweet, meaning it's low in sulfur.
Best of all, the Bakken could be huge. The U.S. Geological Survey (USGS) estimated that the Bakken might hold 413 billion barrels. If so, it would dwarf Saudi Arabia's Ghawar, the world's biggest field, which has produced about 55 billion barrels.
The challenge is getting the oil out. Bakken crude is locked 2 miles underground in a layer of dolomite, a dense mineral that doesn't surrender oil the way more porous limestone does. The dolomite band is narrow, too, averaging just 22 feet in North Dakota.
The USGS said in April that the Bakken holds as much as 4.3 billion barrels that can be recovered using today's engineering techniques. That's a fraction of the oil estimated to be there, but it's still the largest accumulation of crude in the 48 contiguous United States.
North Dakota, where Bakken exploration is most intense now, won't become Saudi Arabia unless technology improves.
For decades, the Bakken was the fool's gold of the oil industry. The name describes a geological formation that looks like an Oreo cookie: two layers of black shale that bleed oil into the middle layer of dolomite. It's named after Henry O. Bakken, the North Dakota farmer who owned the land where the first drilling rig revealed the shale layers in the 1950s.
All of the layers are thin — about 150 feet altogether — and none of them gives up oil easily. In older, vertical wells, oil would often flow for a month and then fizzle.
Now, companies like EOG are drilling horizontally. They go straight down 10,000 feet and then put a slight angle so they hit the Bakken sideways, making a horizontal tunnel as much as 4,500 feet long through the dolomite.
It eventually winds up in a pipeline that runs east to Clearbrook, Minn., and then south to Chicago.

Several billionaires are at work in the Bakken. Harold Hamm's Continental Resources has leases on 487,000 acres in Montana and North Dakota. Hamm, who started out driving a truck, owns 73 percent of Continental, worth $7.9 billion. Philip Anschutz, 68, founder of Qwest and Regal Entertainment, is there, too.
The big winner so far has been EOG, formerly a subsidiary of bankrupt energy trader Enron. It drilled a horizontal well in western North Dakota just north of Parshall — population 1,028 — in April 2006. The well came online a month later and kicked out 1,883 barrels in the first seven days. Unlike the older vertical wells, it's still going.
Northern Oil & Gas, a five-person company near Minneapolis, makes money without actually drilling or operating wells. It leases in promising areas like the Bakken and gets paid when someone else uses the land to drill.
The other people doing well in the Bakken are the mineral owners under the oil wells — folks like John Bartelson. Oil drillers have paid them millions for right of access to the oil deposits.
Bartelson's checks are about to get bigger. One more EOG well just came online, he says, and another is about to. Still another has been permitted for drilling. For now, he's farming. The oil market is fickle, he says. Previous crashes drove the rigs out of North Dakota for years, leaving only the wheat.
"It'll crash again," Bartelson says, sipping on a late-afternoon cup of coffee beside his tractor.
Maybe so. But with crude trading above $135 a barrel, it may be a long time before the rigs leave again, and John Bartelson is likely to be a wealthy man before they do.
