Little Charles #4 (API 42-133-33131) is a plugged well in Eastland County, plugged September 14, 2001, last operated by Corona Exploration Inc..
The RRC has issued one drilling permit, issued June 30, 1981, permitted to 1,500 ft.
It was permitted by Genco Oil & Gas CO. and has since transferred to Corona Exploration Inc. on the wellbore schedule.
Completion filings report one formation top, including Winchell Sand.
Its lease has reported 2.7K barrels of oil and 75 mcf of gas since January 1993, last reporting in October 2001. The lease carries 10 wells, so these are lease totals, not this well alone.
