Abstract
A method for milling a wellbore structure comprising: pumping fluid through a mud motor and a milling tool while the milling tool and the mud motor are moved on a string to mill out a wellbore structure; and conveying a diversion agent with the fluid through the string, mud motor and milling tool to introduce the diversion agent to the wellbore, the diversion agent mitigating fluid loss in a low pressure zone.
