Lee #4 (API 42-451-32307) is a plugged well in Tom Green County, plugged August 16, 2010, last operated by Atlas Operating LLC.

The RRC has issued one drilling permit, issued October 13, 1994, permitted to 4,700 ft.

It was permitted by Jaco Oil & Gas CO. and has since transferred to Atlas Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Palo Pinto, Yankee, Canyon, Strawn.

Its 2 leases have reported 220 barrels of oil and 126K mcf of gas since November 1994, last reporting in February 2014. The leases carry 2 wells, so these are lease totals, not this well alone.
