Delivery tool for tubular placement of an adaptive seat

An adaptive seat delivery assembly for a tubular string, comprising:

• a mandrel;
• an outer piston supported on said mandrel, said mandrel and said outer piston selectively relatively movable;
• an adaptive seat released from said mandrel responsive to said selective relative movement, said adaptive seat, upon being released, moving radially toward the tubular string for support therefrom;
• said selective relative movement initiated by a power charge associated with said piston;
• a retaining sleeve for said adaptive seat moving in tandem with said outer piston;
• at least one locating member axially spaced from said adaptive seat, whereupon movement of said retaining sleeve brings said retaining sleeve in contact with said at least one locating member to retract said at least one locating member radially toward said mandrel;
• an opening in said retaining sleeve through which said at least one locating member extends until an end of said opening in said retaining sleeve engages said at least one locating member to retract said locating member radially toward said mandrel;
• and
• said opening in said retaining sleeve providing access to a bottom of said outer piston, said bottom having the same piston area as a top to said outer piston to put said outer piston in pressure balance to fluids in the tubular string.

An adaptive seat delivery assembly for a tubular string, comprising:

• a mandrel;
• an outer piston supported on said mandrel, said mandrel and said outer piston selectively relatively movable;
• an adaptive seat released from said mandrel responsive to said selective relative movement, said adaptive seat, upon being released, moving radially toward the tubular string for support therefrom;
• said selective relative movement initiated by a power charge associated with said outer piston;
• said outer piston comprising opposed piston surfaces exposed to pressure around the tubing string, said opposed surfaces comprising substantially equal areas so that any net force on said outer piston from the pressure around the tubing string will not move said outer piston against a breakable retainer holding said outer piston to said mandrel.

An adaptive seat delivery assembly for a tubular string, comprising:

• a mandrel;
• a single piston supported on said mandrel, said mandrel and said piston selectively relatively movable;
• an adaptive seat released from said mandrel responsive to said selective relative movement, said adaptive seat, upon being released, moving radially toward the tubular string for support therefrom;
• said selective relative movement initiated by a power charge located in a power charge compartment in said mandrel, said power charge compartment defined at least in part by said single piston, such that gas pressure initiated by setting off said power charge is directly applied to said single piston to create said selective relative movement which results in said adaptive seat and a surrounding retaining sleeve becoming misaligned for said release of said adaptive seat to move toward the tubular.
