Bonanza (San Andres) Unit #503 (API 42-079-31625) is a well in Cochran County operated by Cornerstone Petroleum LLC, completed November 4, 1988 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued December 1, 1982, permitted to 4,938 ft.

It was permitted by Woods Petroleum Corporation and has since transferred to Cornerstone Petroleum LLC on the wellbore schedule.

Completion filings report one formation top, including T. San Andres.

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.

It holds an active disposal or injection permit, with 1.9K barrels injected in the 12 months reported through January 2026.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
