Robertson J.B. #500 (API 42-165-34925) is a well in Gaines County operated by Sabinal Energy Operating LLC, completed February 10, 1996.

The RRC has issued one drilling permit, issued November 9, 1995, permitted to 5,800 ft.

It was permitted by Texaco E & P Inc. and has since transferred to Sabinal Energy Operating LLC on the wellbore schedule.

Completion filings report 6 formation tops, including Anhydrite, Yates, Seven Rivers, Queen.

Its 2 leases have reported 77.2K barrels of oil and 28.6K mcf of gas since September 1995, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.

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