University Block 46 #902 (API 42-105-33410) is a well in Crockett County operated by Mariah Energy Corp., completed July 22, 1981.
The RRC has issued one drilling permit, issued May 7, 1981, permitted to 2,200 ft.
It was permitted by Ten Oil, Inc. 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.
