C. B. Erwin Oil Unit #14 (API 42-215-32309) is a plugged well in Hidalgo County, plugged February 17, 2018, last operated by Pioneer Resources Producing L.P.
The RRC has issued 4 drilling permits (amended twice) between 1996 and 2005, permitted to 8,300 ft.
It was permitted by Magnum Producing, LP and has since transferred to Pioneer Resources Producing L.P on the wellbore schedule.
Completion filings report 2 formation tops, including Miocene (undifferentiated), Frio.
Its 4 leases have reported 1.46K barrels of oil and 196K mcf of gas since August 1996, last reporting in February 2018. The leases carry 4 wells, so these are lease totals, not this well alone.
