Montague County · Montague County Regular field · Vertical
Holt Sand Unit #200A (API 42-337-31520) is a well in Montague County operated by Wako Oil CO. LLC, completed May 5, 1981.
The RRC has issued 2 drilling permits between 1980 and 1990, permitted to 1,800 ft.
It was permitted by O-Rrell Oil Company and has since transferred to Wako Oil CO. LLC on the wellbore schedule.
Completion filings report one formation top, including Cisco.
Its 2 leases have reported 427K barrels of oil and 653 mcf of gas since January 1993, last reporting in July 2026. The leases carry 67 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by O-Rrell Oil Company; the EWA schedule now lists a different operator.
