Russell Clearfork Unit #401 (API 42-165-36194) is a well in Gaines County operated by Hilcorp Energy Company, completed September 11, 2012 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued August 16, 2004, permitted to 8,754 ft.

It was permitted by Xto Energy Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 10 formation tops, including Rustler, Salado, Yates, Seven Rivers.

Its 3 leases have reported 21M barrels of oil and 13.4M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 1,101 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.

Well logs

1 log loaded from the RRC's log index, the latest received Jul 24, 2008. Density, Neutron. 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.
