Denman -C- #21 (API 42-187-30385) is a plugged well in Guadalupe County, plugged March 15, 2012, last operated by Texas Petroleum Investment CO..

The RRC has issued one drilling permit, issued September 13, 1977, permitted to 2,690 ft.

It was permitted by American Petrofina CO. Of Tex. and has since transferred to Texas Petroleum Investment CO. on the wellbore schedule.

Its lease has reported 39.9K barrels of oil and 928 mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 8 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
