While oil patches from the Bakken shale to the Eagle Ford have been getting a lot of attention in recent years, the oil industry is focussed increasingly on one of the oldest and richest basins in the country – the Permian Basin. Permian formations have long trapped hydrocarbons in shale and other tight sands and rock in what was formerly the Permian Sea, an area of what is now 110-degree-heat desert that stretches 100,000 square miles across West Texas and Southeastern New Mexico.
The attention there is not coming so much from companies going out in search of new acreage. Many of them have held acreage in the Permain for decades. Others have accumuated it over the years through a series of mergers and acquisitions. Everyone has known the area held oil – lots of oil – and it was just a matter of time before advances in technology meant they could get a little bit more of it out.
