Martin Nellie C. #23
Andrews County · Martin West (Fusselman) field · Vertical
Martin Nellie C. #23 (API 42-003-35529) is a well in Andrews County operated by Sheridan Production Company LLC, completed August 30, 1990.
The RRC has issued 5 drilling permits between 1986 and 1993, permitted to 9,100 ft.
It was permitted by Oryx Energy Company and has since transferred to Sheridan Production Company LLC on the wellbore schedule.
Completion filings report 15 formation tops, including Triasic Redbeds, Santa Rosa, Rustler, Yates.
Its 4 leases have reported 1.35M barrels of oil and 10.8M mcf of gas since January 1993, last reporting in July 2026. The leases carry 67 wells, so these are lease totals, not this well alone.
