The United States Geological Survey (“USGS”) has just announced the assessment of this country’s largest oil and gas shale deposit located in Texas. You can review a copy of the actual assessment here. The area where the deposit is located is known as the Wolfcamp shale contains 20 billion barrels of oil and 16 trillion cubic feet of natural gas. That is Almost three times more petroleum than found in North Dakota’s Bakken shale in 2013. As can be seen in the map shown here, this deposit covers a wide swath of West Texas.
