Anderson Clarence B #4 (API 42-179-31945) is a well in Gray County operated by Large Operating LLC, completed March 15, 1989 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued January 31, 1989, permitted to 3,550 ft.

It was permitted by Harken Exploration Company and has since transferred to Large Operating LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Red Cave, Brown Dolomite, Arkosic Lime, Granite Wash.

Its lease has reported 65K barrels of oil and 98.4K mcf of gas since January 1993, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
