Crespi -B- #6
Midland County · Spraberry (Trend Area) field · Producing · Vertical
Crespi -B- #6 (API 42-329-41372) is a well in Midland County operated by Pioneer Natural Res. USA Inc., completed April 29, 2017 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended twice), issued December 15, 2016, permitted to 12,000 ft.
It was permitted by JM Cox Resources, L.P. and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.
Completion filings report 9 formation tops, including Santa Rosa, Yates, Seven Rivers, Queen.
Its lease has reported 143K barrels of oil and 412K mcf of gas since January 1993, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
