Upton County · Amacker-Tippett E. (Devonian) field · Horizontal
Zinn #9501H (API 42-461-34113) is a horizontal well in Upton County operated by Cms Oil And Gas Company, completed April 1, 2001.
The RRC has issued 2 drilling permits between 2000 and 2012, permitted to 13,000 ft.
It was permitted by Endeavor Energy Resources L.P. and has since transferred to Cms Oil And Gas Company on the wellbore schedule.
Completion filings report 4 formation tops, including Spraberry, Dean, Wolfcamp, Devonian.
Its 3 leases have reported 188K barrels of oil and 418K mcf of gas since March 2001, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
