Caza 158 #2 (API 42-461-37113) is a well in Upton County operated by QP Inc., completed August 2, 2011 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 9, 2010, permitted to 11,200 ft.
It was permitted by Devon Energy Production CO, L.P. and has since transferred to QP Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Wolfcamp, Strawn.
Its lease has reported 129K barrels of oil and 203K mcf of gas since October 2010, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
