Gentry Ranch #4 (API 42-311-36313) is a well in Mcmullen County operated by First Rock Inc., completed July 19, 2015 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended twice), issued October 28, 2014, permitted to 13,000 ft.
It was permitted by Clearly Petroleum, LLC and has since transferred to First Rock Inc. on the wellbore schedule.
Completion filings report 10 formation tops, including Frio, Catahoula, Yegua, Wilcox.
Its lease has reported 117K barrels of oil and 1.45M mcf of gas since August 2014, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
