Abstract
A whipstock assembly includes a whipstock bodyhaving a whipstock center of gravity offset radially from the central axis of the whipstock body, a counterweight to releasably secured to the whipstock body, with a counterweight having an offset counterweight center of gravity, an orientation device, and a neutralizer. The neutralizer causes the combined whipstock/neutralizer center of gravity to be substantially closer to the central axis of the whipstock body compared to the whipstock center of gravity. An attaching mechanismallows the neutralizer to be returned to the surface after the whipstock body is set in the well.
