Hyvl Unit #1 (API 42-051-31072) is a plugged well in Burleson County, plugged September 2, 2000, last operated by Chesapeake Operating L.L.C..
The RRC has issued one drilling permit, issued October 9, 1980, permitted to 9,000 ft.
It was permitted by Geodynamics Oil & Gas, Inc. and has since transferred to Chesapeake Operating L.L.C. on the wellbore schedule.
Its 2 leases have reported 32.7K barrels of oil and 662K mcf of gas since January 1993, last reporting in October 2022. The leases carry 3 wells, so these are lease totals, not this well alone.
