Winkler County · Halley (Montoya) field · Vertical
Halley S. M. #172L (API 42-495-04746) is a plugged well in Winkler County, plugged January 13, 2014, last operated by Chevron U. S. A. Inc..
The RRC has issued one drilling permit, issued July 22, 1999, permitted to 12,000 ft.
It was permitted by Texaco E & P Inc. and has since transferred to Chevron U. S. A. Inc. on the wellbore schedule.
Its 3 leases have reported 31.8K barrels of oil and 51K mcf of gas since January 1993, last reporting in January 2015. The leases carry 4 wells, so these are lease totals, not this well alone.
