ABSTRACT:
The present invention, in certain embodiments, includes a wellbore tool side support or stabilizer (in one aspect for a concave of a whipstock in a wellbore or in a tubular) which has one or more movable members or bars which are movable from a non-supporting position in, partially in, or on a tool (or device or apparatus) to a position in which it or they provide lateral support on a side of the tool. In certain embodiments such a side support has a plurality of bars which initially are disposed within a tool, such as a whipstock; and which are then moved by an interconnecting setting bar so that they project from a side of the whipstock opposite a concave face of the whipstock, thus insuring correct positioning of the concave face for milling operations. Preferably, the supports or bars are locked in place upon reaching a desired orientation. In one aspect a shock absorber is interconnected between the whipstock and an installation tool or setting tool assembly.
