A connection assembly, system and method for connecting components of a wellsite are provided. The wellsite has a wellbore extending into a subsurface formation, the connection assembly includes a female connector having a cavity extending therein, a floating cartridge having, and a male connector. The female connector or floating cartridge is operatively connectable to a first of the components. The floating cartridge is operatively connectable to the female connector and laterally movable therein. The male connector is receivable in the cavity and is operatively connectable to the second of the components and the floating cartridge such that the male connector and the female connector are movably positionable relative to each other by the floating cartridge whereby a misalignment between the wellsite components is tolerated. The male connector may have a joint pivotally connectable to the floating cartridge.

A whipstock assembly 10 for setting within a casing C on an anchor A diverts a cutting mill M to cut a window in the casing. The whipstock assembly is passed through a restriction positioned above the location where the whipstock assembly is set, is lowered past the restriction in a run in position, and is set within the casing in a set position. The whipstock assembly includes an upper whipstock body 20 having a ramp surface 22, 26, a middle lower whipstock body 60 having a concave guiding face 72, and a lower whipstock body 110 having a concave whipstock diversion face 112. A lower hinge member 118 is provided for positioning the concave whipstock diversion face for diverting the cutting mill, and at least one whipstock positioning member 80, 100 engages the casing when in the set position for positioning the middle whipstock body guiding face. Accordingly the method of the invention, the cutting mill and at least a portion of the a downhole motor may be positioned adjacent the guiding face of the middle whipstock body when initiating rotation of the cutting mill. The whipstock and method of the present invention are particularly well suited for conducting a thru tubing operation, with the tubing OD being less than the ID of the casing which the whipstock assembly is set.

A whipstock assembly includes a whipstock body having 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 mechanism allows the neutralizer to be returned to the surface after the whipstock body is set in the well.
