Oil shale may be booming right now but maintaining output is getting harder and harder. Some say output will peak as soon as 2016 or 2017 and then decline. Production on a typical shale well falls by 69% within just one year- one that was producing say 1000 barrels a day falls to only 300 barrels a day (a more traditional well loses about 50% after two years but can still keep that rate for up to 20 years). To keep things going, you have to continuously keep drilling more and more wells- just to stay where you are today.

The Bakkan region has gone through oil boom/ bust cycles about every 20 years.
A deep water oil well - our other alternative- in the Gulf can cost a $1 billion just to drill a hole.

Highlights:
The U.S. Energy Information Administration estimates that about 29 percent of U.S. oil production today comes from so-called tight oil formations. These dense layers of rock and shale are cracked open by blasting water, sand, and chemicals deep underground, creating fissures that allow the oil to flow into horizontal pipes, some of them thousands of feet long. Production from wells bored into these formations declines by 60 percent to 70 percent in the first year alone, says Allen Gilmer, chairman and chief executive officer of Drillinginfo, which tracks the performance of U.S. wells. Traditional wells take two years to slide 50 percent to 55 percent, and they can keep pumping for 20 years or more.
Global Sustainability’s Hughes estimates the U.S. needs to drill 6,000 new wells per year at a cost of $35 billion to maintain current production. His research also shows that the newest wells aren’t as productive as those drilled in the first years of the boom, a sign that oil companies have already tapped the best spots, making it that much harder to keep breaking records. Hughes has predicted that production will peak in 2017 and fall to 2012 levels within two years.
“The hype about U.S. energy independence and ‘Saudi America’ is deafening if you look at the mainstream media,” Hughes says. “We need to have a much more in-depth and intelligent discussion about this.” On Oct. 7, Abdalla Salem el-Badri, OPEC’s secretary general, said at a conference in Kuwait that U.S. shale producers are “running out of sweet spots” and that output will peak in 2018.
Cost are higher too than conventional wells. Intersting info on what it takes to run an oil shale well:
In September, Steve Slawson, vice president for Slawson Exploration, sat in a trailer about 35 miles north of Oklahoma City, watching monitors as his crew shattered the Mississippi lime thousands of feet below. The well, known as Begonia 1-30H, will cost about $3.7 million. One-third of that is the cost of fracking: First, thin pipes loaded with explosives are threaded into the hole to blast the ancient reef. Then, at a cost of about $80,000, the Begonia will consume 50,000 gallons of hydrochloric acid to dissolve the limestone; another $68,000 will pay for 1,000 gallons of antibacterial solution to kill microorganisms that chew up the pipes; $110,000 goes for a soapy surfactant to reduce friction; $10,000 covers a scale inhibitor to prevent lime buildup; and $230,000 purchases 2 million pounds of sand to prop the fractures open so the oil and gas can flow into the well. Then there’s $300,000 in pumping charges, plus the cost of equipment rental, pipe, and water, which brings the price tag for fracking the well to $1.2 million. A host of other things, from cement to Porta Potty rentals, accounts for the rest of the cost.
There’s little doubt Begonia will produce oil, Slawson says. The question is whether it will be enough to cover the cost of drilling and how quickly. Slawson Exploration’s first Mississippi lime horizontal well, the nearby Wolf 1-29H, produced the equivalent of almost 1,185 barrels a day when it started flowing last year and has paid for itself twice over, Slawson says. After the Wolf, a third of his wells were “dogs,” and only a third have come even close to it.
Slawson sees a few more years of growth in U.S. production if prices stay high. Below $70 a barrel, the number of rigs hunting for oil will drop, and production won’t be far behind, he says. “Like anybody else who is over the age of 50 and has been through the boom-and-bust cycle, I am concerned,” he says.
Companies that borrow heavily to pay for drilling will be hit especially hard if prices decline. Since natural gas prices started falling, Chesapeake has been forced to sell off assets to pay for drilling. It’s also started cutting jobs. Chesapeake would not comment for this story.
The Bakkan region has gone through oil boom/ bust cycles about every 20 years.
