Villarreal #21 (API 42-427-00402) is a well in Starr County operated by Pitco Investments Ltd., completed April 29, 1988.

The RRC has issued one drilling permit, issued April 20, 1988, permitted to 6,712 ft.

It was permitted by Cabot Petroleum Corporation and has since transferred to Pitco Investments Ltd. on the wellbore schedule.

Completion filings report 2 formation tops, including Miocene (undifferentiated), Frio.

Its 2 leases have reported 37.4K barrels of oil and 440K mcf of gas since January 1993, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
