Heidelberg #1 (API 42-317-32788) is a plugged well in Martin County, plugged June 13, 2022, last operated by Prime Operating Company.
The RRC has issued one drilling permit, issued September 21, 1983, permitted to 9,800 ft.
It was permitted by Brazos Petroleum CO. and has since transferred to Prime Operating Company on the wellbore schedule.
Its lease has reported 276K barrels of oil and 593K 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.
