Callihan M. W. -A- #B1 (API 42-055-31481) is a well in Caldwell County operated by Meb LLC, completed August 19, 1980.
The RRC has issued one drilling permit, issued June 20, 1980, permitted to 2,800 ft.
It was permitted by Loscuartos Amigos Oil Group and has since transferred to Meb LLC on the wellbore schedule.
Its 2 leases have reported 3.42K barrels of oil and 944 mcf of gas since January 1993, last reporting in July 2026. The leases carry 18 wells, so these are lease totals, not this well alone.
