Cochran County · Bonanza (San Andres) field · Vertical
Bonanza (San Andres) Unit #1 (API 42-079-31341) is a plugged well in Cochran County, plugged August 31, 2006, last operated by Cornerstone Petroleum LLC.
The RRC has issued one drilling permit, issued January 29, 1981, permitted to 5,550 ft.
It was permitted by Woods Petroleum Corporation and has since transferred to Cornerstone Petroleum LLC on the wellbore schedule.
Its lease has reported 593K barrels of oil and 105K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 52 wells, so these are lease totals, not this well alone.
