Atascosa County · Somerset field · Vertical
Calfas A #5 (API 42-013-32884) is a plugged well in Atascosa County, plugged March 14, 2005, last operated by Calfas Oil LLC.
The RRC has issued one drilling permit, issued August 15, 1984, permitted to 2,000 ft.
It was permitted by Far, Inc. and has since transferred to Calfas Oil LLC on the wellbore schedule.
Completion filings report one formation top, including Anacacho.
Its 2 leases have reported 26.7K barrels of oil and 28 mcf of gas since January 1993, last reporting in July 2026. The leases carry 38 wells, so these are lease totals, not this well alone.
