Leon #7 (API 42-135-40614) is a well in Ector County operated by Firebird Energy LLC, completed September 2, 2011.

The RRC has issued 2 drilling permits between 2010 and 2018, permitted to 10,500 ft.

It was permitted by Fdl Operating, LLC and has since transferred to Firebird Energy LLC on the wellbore schedule.

Completion filings report 4 formation tops, including San Andres, Spraberry, Wolfcamp, Strawn.

Its 2 leases have reported 228K barrels of oil and 365K mcf of gas since April 2011, last reporting in July 2026. The leases carry 15 wells, so these are lease totals, not this well alone.
