Warwink University 18-34 -A- #4 (API 42-475-34520) is a plugged well in Ward County, plugged October 5, 2022, last operated by Callon Petroleum Operating CO.
The RRC has issued one drilling permit, issued October 1, 1997, permitted to 11,800 ft.
It was permitted by Pioneer Natural Res. USA, Inc. and has since transferred to Callon Petroleum Operating CO on the wellbore schedule.
Completion filings report 7 formation tops, including Rustler, T/Delaware, T/Manzinita, T/Brushy Canyon.
Its lease has reported 1.08M barrels of oil and 1.98M mcf of gas since November 1996, with no volume in the three years through April 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
