Cassin #7A
Bexar County · Monksfield (350 Sand) field · Vertical
Cassin #7A (API 42-029-36329) is a plugged well in Bexar County, plugged November 9, 2005, last operated by South Loop Operating L.C..
The RRC has issued one drilling permit, issued February 28, 1985, permitted to 990 ft.
It was permitted by R.D. Oil Company and has since transferred to South Loop Operating L.C. on the wellbore schedule.
Its lease has reported 20.7K barrels of oil and 142 mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 108 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.
