Madison Lois -B- #5 (API 42-317-33589) is a plugged well in Martin County, plugged February 7, 2008, last operated by JM Cox Resources L.P..

The RRC has issued one drilling permit (amended once), issued March 3, 1989, permitted to 12,000 ft.

It was permitted by Cox, John L. and has since transferred to JM Cox Resources L.P. on the wellbore schedule.

Completion filings report 12 formation tops, including Red Beds, Spraberry, Dean, Strawn.

Its lease has reported 69.9K barrels of oil and 412K mcf of gas since January 1993, last reporting in June 2013. The lease carries 4 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.
