Sloan X S E-4 Unit #1
Throckmorton County · X S (Caddo) field · Vertical
Sloan X S E-4 Unit #1 (API 42-447-35322) is a well in Throckmorton County operated by Unit Petroleum Company, completed January 18, 1993.
The RRC has issued one drilling permit, issued November 12, 1992, permitted to 5,500 ft.
It was permitted by Throckmorton Oil, Inc. and has since transferred to Unit Petroleum Company on the wellbore schedule.
Completion filings report one formation top, including Caddo.
Its 3 leases have reported 110K barrels of oil and 78K mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
