Ricker Rupert P. -KO- #15 (API 42-383-38161) is a well in Reagan County operated by Diamondback E&P LLC, completed April 21, 2013 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued January 3, 2013, permitted to 9,950 ft.

It was permitted by Endeavor Energy Resources L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report one formation top, including Spraberry.

Its lease has reported 546K barrels of oil and 5.04M mcf of gas since November 1995, last reporting in July 2026. The lease carries 38 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.
