Leslie #9 (API 42-371-38707) is a well in Pecos County operated by Clark Oil CO., completed June 28, 2013 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued June 17, 2010, permitted to 950 ft.
It was permitted by Griffin Petroleum Company and has since transferred to Clark Oil CO. on the wellbore schedule.
Completion filings report 7 formation tops, including Toborg, Tansil Anhy, 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.
It holds an active disposal or injection permit, with 4.05K barrels injected in the 12 months reported through May 2025.
