Henderson #J 4 (API 42-049-34743) is a plugged well in Brown County, plugged January 20, 1998, last operated by T-Rex Oil & Gas LLC.

The RRC has issued one drilling permit, issued November 14, 1986, permitted to 1,500 ft.

It was permitted by J & R Oil Company and has since transferred to T-Rex Oil & Gas LLC on the wellbore schedule.

Its lease has reported 2.72K barrels of oil and 17 mcf of gas since January 1993, last reporting in July 2026. The lease carries 17 wells, so these are lease totals, not this well alone.
