Abstract
There is described a device for machining apparatus arranged for machining of a portion of a casing positioned in a wellbore, wherein a return fluid conduit extends from the machining apparatus in a direction toward a deposit area arranged in the wellbore. Also described is a method for machining of a portion of a casing positioned in a wellbore, wherein the method comprises the steps of: arranging a return fluid conduit between a machining apparatus and a deposit area or an area connected to the deposit area, providing a particle carrying liquid flow (M) in a direction from the machining apparatus and toward the deposit area, during the machining of the casing leading metal shavings into the liquid flow (M), and directing the liquid flow (M) into the return fluid conduit, as the metal shavings are held back and deposited in the wellbore.
