Guadalupe County · LA Vernia field · Vertical

Bolton Roman E. #4 (API 42-187-32146) is a plugged well in Guadalupe County, plugged May 5, 2005, last operated by Caltex Energy CO..

The RRC has issued one drilling permit, issued June 22, 1982, permitted to 1,000 ft.

It was permitted by J W J Oil Corporation and has since transferred to Caltex Energy CO. on the wellbore schedule.

Its lease has reported 2.29K barrels of oil and 21 mcf of gas since January 1993, last reporting in March 2006. The lease carries 14 wells, so these are lease totals, not this well alone.
