Jennings Ranch D #4 (API 42-505-34136) is a plugged well in Zapata County, plugged April 3, 2012, last operated by Conocophillips Company.
The RRC has issued 2 drilling permits in 2000, permitted to 13,100 ft.
It was permitted by Conoco Inc. and has since transferred to Conocophillips Company on the wellbore schedule.
Completion filings report 3 formation tops, including Perdido, Wilcox, Wills Point.
Its 2 leases have reported 44 barrels of oil and 74.8K mcf of gas since August 2000, with no volume in the three years through April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
