Henderson O C #5 (API 42-237-33722) is a well in Jack County operated by Mammoth Operating LLC, completed May 1, 1981 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued April 16, 1981, permitted to 425 ft.
It was permitted by Jackson, D. L., & Son and has since transferred to Mammoth Operating LLC on the wellbore schedule.
Its lease has reported 1.8K barrels of oil and 238 mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
