Prospector #1 (API 42-317-33959) is a plugged well in Martin County, plugged April 1, 2024, last operated by Endeavor Energy Resources L.P..
The RRC has issued one drilling permit (amended once), issued January 4, 1994, permitted to 12,500 ft.
It was permitted by Collins & Ware, Inc. and has since transferred to Endeavor Energy Resources L.P. on the wellbore schedule.
Completion filings report 6 formation tops, including Wolfcamp, Strawn, U. Mississippian, L. Mississippian.
Its 2 leases have reported 403K barrels of oil and 2.23M mcf of gas since February 1994, last reporting in June 2024. The leases carry 4 wells, so these are lease totals, not this well alone.
