Sanderson #6R (API 42-353-31619) is a plugged well in Nolan County, plugged January 23, 1996, last operated by Cockrell Production CO. Inc..

The RRC has issued 3 drilling permits between 1984 and 2016, permitted to 6,750 ft.

It was permitted by Clear Fork, Incorporated and has since transferred to Cockrell Production CO. Inc. on the wellbore schedule.

Completion filings report 14 formation tops, including Coleman Junction, Elm Creek - Disposal, Wichita-Albany, Wolfcamp.

Its 3 leases have reported 42.2K barrels of oil and 50.5K mcf of gas since January 1993, last reporting in July 2026. The leases carry 7 wells, so these are lease totals, not this well alone.
