Gaines County · Russell (Clearfork Consolidated field · Shut In · Vertical
Russell Clearfork Unit #436 (API 42-165-36571) is a well in Gaines County operated by Hilcorp Energy Company, completed January 3, 2011 and listed as shut in on the RRC schedule, shut in May 1, 2022.
The RRC has issued one drilling permit, issued May 4, 2006, 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 5 formation tops, including Queen, San Andres, Glorieta, Clear Fork.
Its 2 leases have reported 15.4M barrels of oil and 11.3M mcf of gas since November 2005, last reporting volume in August 2026. The leases carry 791 wells, so these are lease totals, not this well alone.

Every well with a location on file around this well, in any state, nearest first.
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 Aug 6, 2009. 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.
