Foster Mary #258 (API 42-335-33518) is a well in Mitchell County operated by Basa Resources Inc., completed April 11, 1990 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 18, 1989, permitted to 3,600 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Basa Resources Inc. on the wellbore schedule.
Completion filings report 5 formation tops, including Yates, Seven Rivers, San Andres, San Angelo.
Its lease has reported 12.8M barrels of oil and 2.65M mcf of gas since January 1993, last reporting in July 2026. The lease carries 495 wells, so these are lease totals, not this well alone.
