Permian Basin

Producing since the 1920s, West Texas and New Mexico, over 5 million barrels per day in the 2020s.

Overview

The Permian is the gift that keeps giving: conventional wells from the 1930s, then horizontal shale after 2010 pushed it past every historic US province. Spraberry, Wolfcamp and Bone Spring horizons stack multiple pay zones. Output above 5 million barrels per day rivals entire OPEC members and repositioned world supply.
