Sullivan D.J. B #101F (API 42-047-31689) is a well in Brooks County operated by Costilla Energy Inc., completed October 3, 1996.
The RRC has issued 2 drilling permits between 1995 and 1996, permitted to 8,600 ft.
It was permitted by Manti Operating Company and has since transferred to Costilla Energy Inc. on the wellbore schedule.
Its 3 leases have reported 26.2K barrels of oil and 591K mcf of gas since September 1994, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
