"The USGS said its estimates are for “continuous unconventional oil,” meaning it’s spread throughout the Wolfcamp and Bone Spring formations rather than concentrated in one place. It said the reserves are “undiscovered,” meaning they have yet to be produced, and that they’re “technically recoverable” with current technologies."
