The RRC has issued one drilling permit, issued August 30, 2017, permitted to 9,000 ft.

It was permitted by Sable Permian Resources Land,LLC and has since transferred to Sable Permian Resources LLC on the wellbore schedule.

Its 2 leases have reported 2.51M barrels of oil and 35.3M mcf of gas since December 2013, last reporting in July 2026. The leases carry 62 wells, so these are lease totals, not this well alone.
