Nueces County · Chapman Ranch E. (Davis) field · Vertical
Chapman Ranch #637 (API 42-355-03234) is a plugged well in Nueces County, plugged February 24, 1993, last operated by Decker Operating CO. L.L.C..
The RRC has issued one drilling permit, issued October 23, 1985, permitted to 4,613 ft.
It was permitted by Champlin Petroleum CO. and has since transferred to Decker Operating CO. L.L.C. on the wellbore schedule.
Its lease has reported 25.7K barrels of oil and 23 mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
