Sterling County · Conger (Penn) field · Vertical
Foster #4 (API 42-431-30898) is a plugged well in Sterling County, plugged August 3, 2000, last operated by Basa Resources Inc..
The RRC has issued one drilling permit, issued August 7, 1980, permitted to 8,400 ft.
It was permitted by Cox, John L. and has since transferred to Basa Resources Inc. on the wellbore schedule.
Its lease has reported 18.3K barrels of oil and 833K mcf of gas since the record begins in January 1993, last reporting volume in April 2026. The lease carries 6 wells, so these are lease totals, not this well alone.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
