Mahlmann Heirs #3 (API 42-157-33144) is a well in Fort Bend County operated by KZ Global Energy LLC, completed September 5, 2014 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued August 18, 2014, permitted to 7,000 ft.
It was permitted by Property Development Group, Inc. and has since transferred to KZ Global Energy LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Dome Caprock - Disposal, Pliocene - Disposal, Wilcox, Caprock.
Its lease has reported 6.46K barrels of oil and 101 mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
