Diamondback Energy is engaged in finding, developing and pumping oil and natural gas from onshore fields that require modern extraction methods, with nearly all of its activity clustered in the Permian Basin spanning West Texas and New Mexico. It is best known for its concentrated footprint there, drilling into formations such as the Spraberry and Wolfcamp layers on the Midland side and the Wolfcamp and Bone Spring layers on the Delaware side of that basin.
Beyond running its own wells, the company holds mineral and royalty stakes across a broad swath of acreage stretching into the Eagle Ford Shale as well as the Permian, which lets it collect income from land it does not operate directly. It also owns and runs midstream assets, including pipeline networks for moving crude oil and gas and a water-handling system, supporting the fields it works in the Midland and Delaware Basins.
Diamondback Energy traces back to 2007 and is based in Midland, Texas. It trades on the NASDAQ under the ticker FANG.
