Chapman H. H. #12 (API 42-055-31086) is a well in Caldwell County operated by Hidden Oaks Oil Company LLC, completed February 27, 1978 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued October 21, 1977, permitted to 2,400 ft.
It was permitted by Delray Oil, Inc. and has since transferred to Hidden Oaks Oil Company LLC on the wellbore schedule.
Its lease has reported 49K barrels of oil and 91K mcf of gas since January 1993, last reporting in July 2026. The lease carries 17 wells, so these are lease totals, not this well alone.
