Taylor Mack A #833H
Winkler County · Keystone (San Andres) field · Horizontal
Taylor Mack A #833H (API 42-495-30318) is a horizontal well in Winkler County operated by Gruy Petroleum Management CO., completed September 1, 1995.
The RRC has issued 2 drilling permits (amended once) between 1995 and 2011, permitted to 5,500 ft.
It was permitted by Cimarex Energy CO. and has since transferred to Gruy Petroleum Management CO. on the wellbore schedule.
Completion filings report 3 formation tops, including Grayburg, San Andres, Holt.
Its 3 leases have reported 1.46M barrels of oil and 2.08M mcf of gas since January 1993, last reporting in July 2026. The leases carry 86 wells, so these are lease totals, not this well alone.
Operator of record
