Slator -B- #12 (API 42-135-10900) is a permitted well in Ector County filed by Apache Corporation; no completion report is on file yet.
The RRC has issued one drilling permit, issued June 13, 2008, permitted to 12,000 ft.
It was permitted by Apache Corporation and has since transferred to Shell Western E&P Inc. on the wellbore schedule.
Its 2 leases have reported 125K barrels of oil and 709K 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.
