Cocodrilo #4H (API 42-041-32503) is a horizontal well in Brazos County operated by Wildfire Energy Operating LLC, completed October 7, 2018 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued February 23, 2018, permitted to 9,000 ft.

It was permitted by Hawkwood Energy Operating, LLC and has since transferred to Wildfire Energy Operating LLC on the wellbore schedule.

Its lease has reported 772K barrels of oil and 820K mcf of gas since April 2015, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
