System and Method for Servicing a Wellbore

摘要

A wellbore servicing system, comprising a sleeve system comprising a ported case, a sliding sleeve within the case and movable between a first sleeve position in which the sleeve restricts fluid communication via the case and a second sleeve position in which the sleeve does not, a radially divided segmented seat movable between a first seat position in which the seat restricts movement of the sleeve and a second seat position in which the seat does not, and a sheath covering a portion of the seat, the sleeve system being transitionable from a first, to a second, to a third mode, in the first mode, the sleeve is in its first position and the seat in its first position, in the second mode, the sleeve is in its first position and the seat in its second position, and, in the third mode, the sleeve is in its second position.

主权项

1. A wellbore servicing system, comprising:
a first sleeve system, the first sleeve system comprising:
a first ported case;a first sliding sleeve at least partially carried within the first ported case and movable relative to the first ported case between a first sleeve position in which the first sliding sleeve restricts fluid communication via the ported case and a second sleeve position in which the first sliding sleeve does not restrict fluid communication via the ported case;a first segmented seat, the first segmented seat being radially divided into a plurality of segments and movable relative to the first ported case between a first seat position in which the first seat restricts movement of the sliding sleeve relative to the ported case and a second seat position in which the first seat does not restrict movement of the sliding sleeve relative to the ported case; anda first sheath forming a continuous layer that covers one or more surfaces of the first segmented seat,the first sleeve system being transitionable from a first mode to a second mode and transitionable from the second mode to a third mode,wherein, when in the first mode, the first sliding sleeve is retained in the first sleeve position and the first segmented seat is retained in the first seat position,wherein, when in the second mode, the first sliding sleeve is retained in the first sleeve position and the first segmented seat is in the second seat position, andwherein, when in the third mode, the first sliding sleeve is in the second sleeve position.
