Brooks County · Pita (D-5 B-C) field · Vertical
Sullivan D. J. -B- #78 (API 42-047-31383) is a well in Brooks County operated by Costilla Energy Inc., completed October 29, 1984.
The RRC has issued 2 drilling permits between 1984 and 1992, permitted to 8,750 ft.
It was permitted by Exxon Corp. and has since transferred to Costilla Energy Inc. on the wellbore schedule.
Its 3 leases have reported 196K barrels of oil and 705K mcf of gas since January 1993, last reporting in July 2026. The leases carry 24 wells, so these are lease totals, not this well alone.
