Harrison County · Waskom (Travis Peak 7) field · Vertical
Sanders A #4 (API 42-203-31128) is a plugged well in Harrison County, plugged December 20, 2008, last operated by Exco Production Company LP.
The RRC has issued 2 drilling permits between 1984 and 2004, permitted to 7,000 ft.
It was permitted by Winchester Production Company and has since transferred to Exco Production Company LP on the wellbore schedule.
Completion filings report 6 formation tops, including Mass Anhyd, Mass. Anhyd, Massive Anhydrite (marker), Rodessa.
Its 4 leases have reported 33.6K barrels of oil and 36.9K mcf of gas since January 1993, last reporting in January 2009. The leases carry 4 wells, so these are lease totals, not this well alone.
