Riley Myrl #5 (API 42-173-31759) is a plugged well in Glasscock County, plugged December 17, 2024, last operated by Pioneer Natural Res. USA Inc..

The RRC has issued one drilling permit, issued December 6, 1984, permitted to 8,500 ft.

It was permitted by Cox, John L. and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.

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

Its lease has reported 120K barrels of oil and 400K mcf of gas since January 1993, last reporting volume in April 2024. The lease carries 5 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.
