Mathis #2
Haskell County · Obrien (Strawn) field · Vertical
Mathis #2 (API 42-207-30897) is a plugged well in Haskell County, plugged May 22, 1992, last operated by Chaparral Energy L.L.C..
The RRC has issued one drilling permit, issued February 20, 1980, permitted to 5,000 ft.
It was permitted by Walter Exploration Inc. and has since transferred to Chaparral Energy L.L.C. on the wellbore schedule.
Its lease has reported 4.43K barrels of oil and 24 mcf of gas since January 1993, last reporting in February 2011. The lease carries 2 wells, so these are lease totals, not this well alone.
