Buerger Lena #4
Frio County · Pearsall (Austin Chalk) field · Vertical
Buerger Lena #4 (API 42-163-31548) is a plugged well in Frio County, plugged October 4, 2012, last operated by Hughes Dan A. Company L.P..
The RRC has issued one drilling permit, issued November 15, 1977, permitted to 7,100 ft.
It was permitted by Convest Energy Corporation and has since transferred to Hughes Dan A. Company L.P. on the wellbore schedule.
Its 3 leases have reported 37.7K barrels of oil and 2.61K mcf of gas since January 1993, last reporting in July 2026. The leases carry 6 wells, so these are lease totals, not this well alone.
