North Stiles Spraberry Unit #1727 (API 42-383-35556) is a well in Reagan County operated by Prime Operating Company, completed June 2, 2005 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued May 4, 2005, permitted to 8,548 ft.

It was permitted by Mariner Energy, Inc. and has since transferred to Prime Operating Company on the wellbore schedule.

Completion filings report 3 formation tops, including Spraberry, Dean, Wolfcamp.

Its lease has reported 1.97M barrels of oil and 11.4M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 79 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
