Midland County · Spraberry (Trend Area) field · Producing · Vertical
Lupin Txl Fee #4145M (API 42-329-39331) is a well in Midland County operated by Diamondback E&P LLC, completed February 4, 2015 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued June 18, 2014, permitted to 11,234 ft.
It was permitted by Chevron U. S. A. Inc. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 9 formation tops, including Santa Rosa, Yates, Seven Rivers, Queen.
Its lease has reported 3.45M barrels of oil and 16.4M mcf of gas since July 2010, last reporting in July 2026. The lease carries 95 wells, so these are lease totals, not this well alone.
