Mash #1
Denton County · Boonsville (Bend Congl. Gas) field · Producing · Vertical
Mash #1 (API 42-121-31828) is a well in Denton County operated by Hawkbend LLC, completed September 11, 2007 and listed as producing on the RRC schedule, shut in July 1, 2026.
The RRC has issued 2 drilling permits between 2003 and 2007, permitted to 8,860 ft.
It was permitted by Burlington Resources O & G CO LP and has since transferred to Hawkbend LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Caddo, Barnett, Viola.
Its 2 leases have reported 577 barrels of oil and 176K mcf of gas since April 2003, last reporting volume in March 2026. The leases carry 2 wells, so these are lease totals, not this well alone.

Well logs
2 logs loaded from the RRC's log index, the latest received Aug 17, 2006. Density, Neutron, Resistivity. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
