Ector County · Harper field · Shut In · Vertical
East Harper Unit #237 (API 42-135-35186) is a well in Ector County operated by Aghorn Operating Inc., completed October 10, 1996 and listed as shut in on the RRC schedule, shut in January 1, 2000.
The RRC has issued one drilling permit, issued November 26, 1985, permitted to 4,700 ft.
It was permitted by Shell Western E&P Inc. and has since transferred to Aghorn Operating Inc. on the wellbore schedule.
Completion filings report 6 formation tops, including Rustler, Yates, Seven Rivers, Queen.
Its lease has reported 2.95M barrels of oil and 843K mcf of gas since January 1993, last reporting volume in February 2026. The lease carries 266 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
