Cockburn H. C. #137 (API 42-481-33118) is a well in Wharton County operated by Orx Resources L.L.C., completed March 10, 1988 and listed as shut in on the RRC schedule, shut in September 1, 2024.
The RRC has issued one drilling permit, issued December 7, 1987, permitted to 7,000 ft.
It was permitted by Exxon Corp. and has since transferred to Orx Resources L.L.C. on the wellbore schedule.
Completion filings report 2 formation tops, including Top Of Marginulina, Frio.
Its lease has reported 6.56M barrels of oil and 5.82M mcf of gas since the record begins in January 1993, last reporting volume in July 2026. The lease carries 143 wells, so these are lease totals, not this well alone.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
