Shell-Perkins #10 (API 42-003-39715) is a well in Andrews County operated by Highmark Energy Operating LLC, completed February 25, 2006 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 5, 2005, permitted to 10,000 ft.
It was permitted by Cog Operating LLC and has since transferred to Highmark Energy Operating LLC on the wellbore schedule.
Completion filings report 6 formation tops, including Yates, San Andres, Wolfcamp, Pennsylvanian.
Its lease has reported 204K barrels of oil and 385K mcf of gas since January 1993, last reporting in July 2026. The lease carries 10 wells, so these are lease totals, not this well alone.
