Bexar County · Fairfield field  · Vertical

Jackel C.J. #4 (API 42-029-36377) is a plugged well in Bexar County, plugged July 2, 2008, last operated by Diamond Trading & Pipeline Corp.

The RRC has issued one drilling permit, issued March 18, 1985, permitted to 1,400 ft.

It was permitted by Bay Rock Operating Company and has since transferred to Diamond Trading & Pipeline Corp on the wellbore schedule.

Completion filings report 3 formation tops, including Escondido, Olmos, Anachanco.

Its lease has reported 1.26K barrels of oil and 39 mcf of gas since January 1993, last reporting in July 2026. The lease carries 9 wells, so these are lease totals, not this well alone.
