Gcwa #1 (API 42-167-31354) is a plugged well in Galveston County, plugged January 5, 2016, last operated by Cwoc.
The RRC has issued 2 drilling permits (amended once) between 2001 and 2002, permitted to 13,500 ft.
It was permitted by Samedan Oil Corporation and has since transferred to Cwoc on the wellbore schedule.
Completion filings report 2 formation tops, including Banfield Sd, Anomalina Shale.
Its 2 leases have reported 27.4K barrels of oil and 51.3K mcf of gas since September 2001, last reporting in February 2016. The leases carry 2 wells, so these are lease totals, not this well alone.
