Royal Dutch Shell (RDS.A) recently announced that it would be selling off its holdings in the Eagle Ford, Mississippian Lime, and the Niobrara formation. This shouldn't come as too much of a surprise because Shell has not been able to crack the code of shale drilling, and it has plenty of other projects it can develop instead. There is one company, though, that could really be hurt by this decision: Quicksilver Resources (NYSE: KWK)

Quicksilver and Shell were slated to jointly develop 850,000 acres in the Niobrara, and Shell was going to pay a large chunk of the development costs. Now that Shell is looking to get out, the company is going to have to rely on its other assets even more. Tune into the video below to see why this could be devastating for Quicksilver and whether top Niobrara drillers Whiting Petroleum (WLL) or Noble Energy (NBL) would consider these assets.
