Brazos County · Navasota River (Cretaceous Lwr.) field · Horizontal
Reser-Sanders Unit #1RE (API 42-041-31792) is a plugged horizontal well in Brazos County, plugged November 7, 2018, last operated by Magnolia Oil & Gas Operating LLC.
The RRC has issued 2 drilling permits between 1993 and 2007, permitted to 12,000 ft.
It was permitted by Anadarko E&P Company LP and has since transferred to Magnolia Oil & Gas Operating LLC on the wellbore schedule.
Completion filings report 6 formation tops, including Midway, Pecan Gap, Austin Chalk, Upper Cretaceous.
Its 2 leases have reported 109K barrels of oil and 670K mcf of gas since January 1994, last reporting in November 2018. The leases carry 2 wells, so these are lease totals, not this well alone.
