Sterling County · Jameson (Strawn) field · Shut IN · Vertical
Knight #4 (API 42-431-31817) is a well in Sterling County operated by Pima Energy LLC, completed August 14, 1986 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued June 4, 1986, permitted to 7,350 ft.
It was permitted by Gco Drilling Company and has since transferred to Pima Energy LLC on the wellbore schedule.
Completion filings report 3 formation tops, including B/Cisco Lime, Canyon, Strawn.
Its lease has reported 23.8K barrels of oil and 478K mcf of gas since January 1993, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
