State Tract 563-L #4 (API 42-703-30328) is a plugged well in Matgrda IS-LB County, plugged March 14, 2007, last operated by Tri-Union Development Corp..

The RRC has issued 2 drilling permits between 1984 and 1987, permitted to 8,600 ft.

It was permitted by Conquest Exploration Company and has since transferred to Tri-Union Development Corp. on the wellbore schedule.

Completion filings report 5 formation tops, including 5100 Sand Marker, 5100' Sand Marker, 6825' Sand, 6970' Sand.

Its 2 leases have reported 28.8K barrels of oil and 48.3K mcf of gas since January 1993, last reporting in November 2008. The leases carry 2 wells, so these are lease totals, not this well alone.
