Isaacs -209- #3209 (API 42-211-31279) is a well in Hemphill County operated by Mountainside Energy Operating L, completed January 10, 2000 and listed as producing on the RRC schedule.
The RRC has issued 3 drilling permits between 1980 and 1999, permitted to 11,710 ft.
It was permitted by Chevron U. S. A. Inc. and has since transferred to Mountainside Energy Operating L on the wellbore schedule.
Completion filings report 4 formation tops, including Brown Dolomite, Douglas, Oswego, Granite Wash.
Its 2 leases have reported 26.2K barrels of oil and 1.57M mcf of gas since January 1993, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
