Abstract
A milling and wellbore metal recovery assembly includes a milling assembly that can mill a casing disposed in a wellbore. A primary debris removal assembly is connected to the milling assembly and can reside uphole of the milling assembly. The primary debris removal assembly can clear debris resulting from the milling assembly milling the casing disposed in the wellbore by reverse circulating wellbore fluid in an uphole direction from an annulus formed by the wellbore and through the primary debris removal assembly. A second debris removal assembly is connected to the primary debris removal assembly, and can reside uphole of the primary debris removal assembly. The secondary debris removal assembly can clear debris resulting from the milling assembly milling the casing by circulating wellbore fluid in a downhole direction through the secondary debris removal assembly and then in the uphole direction through the annulus towards a surface of the wellbore.
