University 9-31 #8HR (API 42-383-38404) is a horizontal well in Reagan County operated by Sable Permian Resources LLC, completed December 12, 2017.
The RRC has issued 2 drilling permits between 2013 and 2017, permitted to 9,000 ft.
It was permitted by Fdl Operating, LLC and has since transferred to Sable Permian Resources LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Yates, Grayburg, San Andres, Wolfcamp.
Its 2 leases have reported 2.24M barrels of oil and 5.08M mcf of gas since October 2011, last reporting in July 2026. The leases carry 27 wells, so these are lease totals, not this well alone.
