Martinez Adela #4
Bexar County · Fairfield field · Producing · Vertical
Martinez Adela #4 (API 42-029-31333) is a well in Bexar County operated by Calk Roger D., completed April 1, 1981 and listed as producing on the RRC schedule, shut in September 1, 2026.
The RRC has issued one drilling permit, issued February 5, 1981, permitted to 1,367 ft.
It was permitted by T. W. Oil CO. and has since transferred to Calk Roger D. on the wellbore schedule.
Its lease has reported 13.9K barrels of oil and 17 mcf of gas since January 1993, last reporting volume in March 2026. The lease carries 10 wells, so these are lease totals, not this well alone.
