USGS Assessment Of The Spraberry Formation, Midland Basin, 2017

The abstract from the USGS:

Using a geology-based assessment methodology, the U.S. Geological Survey estimated mean resources of 4.2 billion barrels of oil and 3.1 trillion cubic feet of gas in the Spraberry Formation of the Midland Basin, Permian Basin Province, Texas.

The Spraberry is both a conventional (vertical wells) and an unconventional (continuous; horizontal wells) play. The Spraberry is only under the Midland division of the Permian.

The Permian is divided into three divisions -- the Midland (east), Central Basin, and the Delaware (west).

Other than the Wolfcamp and the Spraberry I am not aware of a recent USGS assessment of other formations or plays in the Permian.

The USGS recently posted its assessment of the Eagle Ford in Texas.

The USGS is currently assessing the Bakken/Three Forks in the Williston Basin, which will update the 2013 assessment.
