Wharton County · Magnet Withers field · Shut In · Vertical
Cockburn H. C. #154 (API 42-481-34964) is a well in Wharton County operated by Orx Resources L.L.C., completed February 22, 2010 and listed as shut in on the RRC schedule, shut in September 1, 2025.
The RRC has issued 2 drilling permits between 2008 and 2009, permitted to 7,500 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 3 formation tops, including Anahuac, Het, Frio.
Its 2 leases have reported 6.99M barrels of oil and 6.32M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 164 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Jun 24, 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.
