Cockburn H. C. #158 (API 42-481-34987) is a well in Wharton County operated by Orx Resources L.L.C., completed August 4, 2008 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued May 2, 2008, permitted to 5,650 ft.
It was permitted by Milagro Exploration, LLC and has since transferred to Orx Resources L.L.C. on the wellbore schedule.
Completion filings report 4 formation tops, including Anahuac, Het, Marg 1, Frio.
Its lease has reported 6.54M barrels of oil and 5.82M mcf of gas since the record begins in January 1993, last reporting volume in April 2026. The lease carries 143 wells, so these are lease totals, not this well alone.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

Well logs
1 log loaded from the RRC's log index, the latest received Jul 18, 2011. Density, Neutron, Resistivity. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
