Winkler County · Emperor (Wichita Albany) field · Vertical
Maxwell 23 #1 (API 42-495-32747) is a plugged well in Winkler County, plugged January 28, 2017, last operated by Chevron U. S. A. Inc..
The RRC has issued 3 drilling permits (amended 3 times) between 1999 and 2000, permitted to 8,500 ft.
It was permitted by Pogo Producing CO. and has since transferred to Chevron U. S. A. Inc. on the wellbore schedule.
Completion filings report 16 formation tops, including Rustler, Tansil, Yates, Seven Rivers.
Its 3 leases have reported 8.64K barrels of oil and 247K mcf of gas since April 1999, last reporting in August 2017. The leases carry 3 wells, so these are lease totals, not this well alone.
