Richardson T. J. #1 (API 42-275-31984) is a plugged well in Knox County, plugged October 29, 2015, last operated by Cholla Petroleum Inc..

The RRC has issued one drilling permit, issued February 15, 1991, permitted to 5,500 ft.

It was permitted by Conoco Inc. and has since transferred to Cholla Petroleum Inc. on the wellbore schedule.

Completion filings report 2 formation tops, including 4800' Strawn, 5100 Strawn.

Its 3 leases have reported 277K barrels of oil and 1.58K mcf of gas since January 1993, last reporting in May 2016. The leases carry 7 wells, so these are lease totals, not this well alone.
