Gaines County · Robertson N. (Clear Fork 7100) field · Producing · Vertical
Central Robertson Clearfork Unit #1262 (API 42-165-36421) is a well in Gaines County operated by Hilcorp Energy Company, completed November 16, 2005 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 23, 2005, permitted to 7,249 ft.
It was permitted by Occidental Permian Ltd. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 4 formation tops, including Grayburg, San Andres, Glorieta, Clear Fork.
Its lease has reported 19.6M barrels of oil and 7.81M mcf of gas since the record begins in January 1993, last reporting volume in April 2026. The lease carries 154 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 Feb 8, 2007. Density, Gamma ray, 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.
