Gorilla 20 #17H (API 42-389-34786) is a horizontal well in Reeves County operated by Permian Resources Operating LLC, completed July 17, 2015 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued February 20, 2015, permitted to 12,500 ft.

It was permitted by Oxy USA Wtp LP and has since transferred to Permian Resources Operating LLC on the wellbore schedule.

Completion filings report 8 formation tops, including Castile, Permian (undifferentiated), Bell Canyon, Delaware.

Its lease has reported 1.6M barrels of oil and 2.66M mcf of gas since February 2012, last reporting in July 2026. The lease carries 11 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
