Dodge Granville M. Est. #231 (API 42-227-34462) is a well in Howard County operated by Grayrock Energy II LLC, completed August 19, 1989 and listed as shut in on the RRC schedule, shut in April 1, 2013.

The RRC has issued one drilling permit, issued July 14, 1989, permitted to 2,910 ft.

It was permitted by Arco Oil & Gas CO. and has since transferred to Grayrock Energy II LLC on the wellbore schedule.

Completion filings report 3 formation tops, including San Andres, San Angelo, Clear Fork.

Its lease has reported 5.2M barrels of oil and 438K mcf of gas since January 1993, last reporting in July 2026. The lease carries 262 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
