Hoyt Joan Crews #10 (API 42-235-32923) is a well in Irion County operated by Comstock Energy LLC, completed March 19, 2024 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued March 30, 1990, permitted to 6,700 ft.
It was permitted by Cass Oil Company and has since transferred to Comstock Energy LLC on the wellbore schedule.
Completion filings report 3 formation tops, including San Angelo, Wolfcamp, Canyon.
Its lease has reported 345K barrels of oil and 2.8M mcf of gas since January 1993, last reporting in July 2026. The lease carries 20 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 3.03K barrels injected in the 12 months reported through December 2025.
