Gaines County · Seminole East (San Andres) field · Injection · Vertical
Seminole East (San Andres) Unit #503A (API 42-165-33615) is a well in Gaines County operated by Block T Petroleum Inc., completed July 17, 1987 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued April 15, 1987, permitted to 5,725 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Block T Petroleum Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Rustler, Yates, San Andres.
Its lease has reported 3.6M barrels of oil and 582K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 128 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 98.5K barrels injected in the 12 months reported through October 2025.
