Collier Unit #2 (API 42-497-31298) is a plugged well in Wise County, plugged May 3, 2008, last operated by Georgetown Operating Company.
The RRC has issued one drilling permit, issued August 21, 1978, permitted to 6,100 ft.
It was permitted by Mulkey Engineering CO., Inc. and has since transferred to Georgetown Operating Company on the wellbore schedule.
Its 2 leases have reported 114 barrels of oil and 21.6K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
