Crockett County · Block 46 East (Grayburg) field · Vertical
University Block 46 #2-10 (API 42-105-34303) is a well in Crockett County operated by Mariah Energy Corp., completed February 10, 1983.
The RRC has issued one drilling permit, issued December 31, 1982, permitted to 1,850 ft.
It was permitted by Worth Petroleum Company and has since transferred to Mariah Energy Corp. on the wellbore schedule.
Its 2 leases have reported 72.3K barrels of oil and 46.7K mcf of gas since January 1993, last reporting in July 2026. The leases carry 21 wells, so these are lease totals, not this well alone.
