Mcdaniel Brothers #1 (API 42-173-31391) is a well in Glasscock County operated by Endeavor Energy Resources L.P., completed June 10, 1992.
The RRC has issued 3 drilling permits (amended once) between 1983 and 1998, permitted to 11,100 ft.
It was permitted by Stephens, Autry C. and has since transferred to Endeavor Energy Resources L.P. on the wellbore schedule.
Completion filings report 7 formation tops, including Yates, Spraberry, Wichita-Albany, Wolfcamp.
Its 3 leases have reported 39.9K barrels of oil and 360K mcf of gas since January 1993, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
