Heard Clement #18 (API 42-391-30078) is a plugged well in Refugio County, plugged September 30, 2016, last operated by Hilcorp Energy Company.
The RRC has issued one drilling permit, issued September 13, 1982, permitted to 4,500 ft.
It was permitted by Quintana Pet. Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report one formation top, including No Change.
Its lease has reported 9.85K barrels of oil and 17.9K mcf of gas since January 1993, last reporting in November 2016. The lease carries 3 wells, so these are lease totals, not this well alone.
