Martin R. S. -C- #C 7R (API 42-131-37419) is a well in Duval County operated by Hilcorp Energy Company, completed November 27, 1990 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued November 1, 1990, permitted to 1,150 ft.
It was permitted by Morsey Oil & Gas Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report one formation top, including Cole.
Its lease has reported 59.7K barrels of oil and 111 mcf of gas since January 1993, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
