Gaines County · Robertson N. (Clear Fork 7100) field · Producing · Vertical
South Central Robertson Unit #66 (API 42-165-32455) is a well in Gaines County operated by Crescent Energy Operating LLC, completed February 26, 1983 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 10, 1982, permitted to 7,250 ft.
It was permitted by Samedan Oil Corporation and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.
Its lease has reported 20.4M barrels of oil and 10M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 145 wells, so these are lease totals, not this well alone.
