Cockburn H. C. #135 (API 42-481-32871) is a well in Wharton County operated by Orx Resources L.L.C., completed January 27, 1989 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits in 1985, permitted to 6,250 ft.

It was permitted by Exxon Corp. and has since transferred to Orx Resources L.L.C. on the wellbore schedule.

Completion filings report one formation top, including 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.

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