Cockburn H.C. #95 (API 42-481-30267) is a well in Wharton County operated by Exxon Corp., completed October 4, 1988.

The RRC has issued 5 drilling permits between 1982 and 2012, permitted to 5,700 ft.

It was permitted by Milagro Exploration, LLC and has since transferred to Exxon Corp. on the wellbore schedule.

Completion filings report 3 formation tops, including Anahuac, Marginulina, Frio.

Its 4 leases have reported 6.54M barrels of oil and 5.86M mcf of gas since January 1993, last reporting in July 2026. The leases carry 145 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
