Matthews J. B. #21 (API 42-417-36155) is a plugged well in Shackelford County, plugged November 27, 2000, last operated by Wells Oilfield Services Inc..

The RRC has issued one drilling permit, issued January 29, 1985, permitted to 1,999 ft.

It was permitted by Smith, Roy H., Drlg. CO. and has since transferred to Wells Oilfield Services Inc. on the wellbore schedule.

Completion filings report 2 formation tops, including Buff Creek, Cooke Sand.

Its lease has reported 9.37K barrels of oil and 203 mcf of gas since January 1993, last reporting in August 2003. The lease carries 13 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
