Ector County · Penwell field · Shut In · Vertical
Penwell Unit #1373 (API 42-135-35654) is a well in Ector County operated by Ctoc Energy LLC, completed August 22, 2002 and listed as shut in on the RRC schedule, shut in January 1, 1998.
The RRC has issued one drilling permit, issued September 18, 1987, permitted to 3,900 ft.
It was permitted by Texaco Producing Inc. and has since transferred to Ctoc Energy LLC on the wellbore schedule.
Its lease has reported 6.85M barrels of oil and 2.21M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 289 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
