Leslie #12 (API 42-371-38817) is a well in Pecos County operated by Clark Oil CO., completed February 21, 2012 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued May 30, 2011, permitted to 800 ft.

It was permitted by Griffin Petroleum Company and has since transferred to Clark Oil CO. on the wellbore schedule.

Completion filings report 8 formation tops, including Torborg A, Toborg, Tansil Anhyd, Rustler.

Its lease has reported 116K barrels of oil since January 2008, last reporting in July 2026. The lease carries 16 wells, so these are lease totals, not this well alone.
