Langford 36 #1
Upton County · Spraberry (Trend Area) field · Vertical
Langford 36 #1 (API 42-461-32415) is a plugged well in Upton County, plugged January 31, 1996, last operated by Prime Operating Company.
The RRC has issued one drilling permit, issued June 3, 1985, permitted to 8,000 ft.
It was permitted by Baytech, Inc. and has since transferred to Prime Operating Company on the wellbore schedule.
Completion filings report 2 formation tops, including Clear Fork, Spraberry.
Its lease has reported 2.57K barrels of oil and 25.2K mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
