Gaines County · Russell (Clearfork Consolidated field · Producing · Vertical
Russell Clearfork Unit #312 (API 42-165-36198) is a well in Gaines County operated by Hilcorp Energy Company, completed April 5, 2011 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued August 24, 2004, permitted to 8,772 ft.
It was permitted by Xto Energy Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 12 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.

Well logs
1 log loaded from the RRC's log index, the latest received Jul 23, 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.
