Calton A. D. #4
Milam County · Minerva-Rockdale field · Producing · Vertical
Calton A. D. #4 (API 42-331-31337) is a well in Milam County operated by 4c Oil LLC, completed February 14, 1983 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued March 25, 1982, permitted to 1,600 ft.
It was permitted by Trophy Oil CO. and has since transferred to 4c Oil LLC on the wellbore schedule.
Its lease has reported 4.62K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Trophy Oil Co.; the EWA schedule now lists a different operator.
