Bash #11
Winkler County · Keystone (Colby) field · Vertical
Bash #11 (API 42-495-31274) is a plugged well in Winkler County, plugged October 31, 2011, last operated by Hilcorp Energy Company.
The RRC has issued one drilling permit, issued November 7, 1980, permitted to 3,450 ft.
It was permitted by Phillips Petroleum Company and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 7 formation tops, including Rustler, Tansill, Yates, Seven Rivers.
Its lease has reported 10.7K barrels of oil and 218K mcf of gas since the record begins in January 1993, with no volume in the three years through August 2026. The lease carries 10 wells, so these are lease totals, not this well alone.

No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
