Mary K. Shirk #8 (API 42-461-38714) is a well in Upton County operated by Bcp Resources LLC, completed July 26, 2013 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued April 8, 2013, permitted to 10,600 ft.

It was permitted by Hunt Oil Company and has since transferred to Bcp Resources LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Clear Fork, Spraberry, Dean, Wolfcamp.

Its lease has reported 73.9K barrels of oil and 298K mcf of gas since August 2011, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
