Cavasso Creek -A- #1 (API 42-007-30872) is a plugged well in Aransas County, plugged March 26, 2014, last operated by T-C Oil Company LLC.

The RRC has issued 5 drilling permits between 2006 and 2011, permitted to 10,000 ft.

It was permitted by T - C Oil Company and has since transferred to T-C Oil Company LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Lagarto, Miocene (undifferentiated), Catahoula, Frio.

Its 6 leases have reported 33.3K barrels of oil and 2.43M mcf of gas since January 2007, last reporting in November 2014. The leases carry 6 wells, so these are lease totals, not this well alone.
