Abstract: Bearing assemblies for downhole tools include a compensator member operatively associated with a slidable member and a bearing member. The slidable member is movable longitudinally relative to the bearing member. Such movement of slidable member occurs when a force acts upwardly on the downhole tool. Thus, the slidable member facilitates absorption of the upward force acting on the downhole tool. During movement of the slidable member, the compensator member is moved from its expanded position to one of its plurality of compressed positions. As a result, the compensator member becomes biased or further biased toward the expanded position. After the upward force dissipates, the compensator member releases some of its stored energy to move from a compressed position toward the expanded position. Longitudinal movement of the slidable member facilitates maintaining engagement of the downhole tool in its working position so that interruptions of operations are minimized.

Abstract: The cutting structure on the lower mill is arrayed in rows that are preferably parallel. The cutting structure in each row is made sharper and more durable than prior designs with the objective of cutting the window higher than where the window mill started the window. The use of the rows increases the contact stress of the inserts on the casing inside wall because at any given time fewer and sharper inserts are cutting the casing wall to lengthen the window. As a row wears down the next row takes over to continue the cutting where the previous row was active and to further penetrate the casing wall. The cutout angle can also increase as this occurs. As a result a decreased insert density results in more effective casing wall cutting to extend the window to allow larger tools to exit into the window off the whipstock.
