Newly exploited tight oil formations account for more than 100% of the increase in U.S. field production of crude oil since 2005. But that doesn't mean it's easy to make money getting oil out of the ground this way.
The Wall Street Journal reported last week:
Royal Dutch Shell (RDSA) plans to sell its stake in the Eagle Ford Shale in South Texas, following a $2 billion write-down of North American assets that the company announced in August.
Shell's sale of leases on 106,000 acres in the oil-and-gas-rich region illustrates the struggles major oil companies have had in places where smaller energy firms have thrived.
Shell said the Eagle Ford holdings didn't meet the company's targets for size and profitability.

An August analysis by Reuters of the company's write-downs cautioned:
However, write downs by Shell and some other majors are a sign they came to the shale boom late in the day, overpaying for lower-quality and less well-explored assets-- not that the shale revolution is stuttering.
The most successful company in the Eagle Ford has been EOG, which produced 94,000 barrels a day from the Eagle Ford in 2012. That's almost a quarter of the 399,000 b/d that the Texas Railroad Commission reported was produced by all the Eagle Ford producers put together in 2012, and a 150% increase over EOG's 2011 Eagle Ford production. But it's interesting that even though EOG reported an average price received around $98/barrel in 2012 compared to $93 in 2011, the company's operating income for the year was down 30% from 2011. Gains in revenue were outweighed by increases in marketing and depletion charges.
Conoco Phillips (COP) produced 89,000 b/d from the Eagle Ford in 2012:Q4, almost as much as EOG, and a 144% increase over what the company produced from Eagle Ford in 2011. Although there are lots of other factors besides Eagle Ford that matter for COP's bottom line, operating income was basically flat year-to-year despite the success in the Eagle Ford. Chesapeake (CHK), another key Eagle Ford producer, reported a big operating loss for 2012.

To be sure, other companies are still doing well with the Eagle Ford and other tight formations. But among the challenges to making on-going profits at this game are the very rapid rates at which production flows decline after peaking and the fact that the vast majority of wells produce very little compared to those that receive the most publicity.

Getting oil from these sources is critical for America's energy future. That makes it all the more sobering that a savvy company like Shell has decided it wants no part in it.
