Reagan County · Lin (Wolfcamp) field · Horizontal
University 9-31 #10H (API 42-383-39908) is a horizontal well in Reagan County operated by Sable Permian Resources LLC, completed December 18, 2017.
The RRC has issued one drilling permit, issued June 22, 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 9 formation tops, including Queen, Grayburg, San Andres, Clear Fork.
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.
