Abstract
A system for servicing a subterranean formation comprising a wellbore completion string comprising a first master activatable stimulation assembly, a first slave activatable stimulation assembly, wherein the first slave activatable stimulation assembly activates responsive to activation of the first master stimulation assembly; a second master activatable stimulation assembly, and a second slave activatable stimulation assembly, wherein the second slave activatable stimulation assembly activates responsive to activation of the second master stimulation assembly.
Claims20
A system for servicing a subterranean formation comprising:
- a wellbore completion string comprising:
- a first master activatable stimulation assembly comprising a first master sleeve, the first master sleeve having a first seat, wherein activation of the first master activatable stimulation assembly provides a first route of fluid communication via one or more ports of the first master activatable stimulation assembly from an interior flow path of the completion string to an area adjacent the one or more ports of the first master activatable stimulation assembly and exterior to the completion string;
- a first slave activatable stimulation assembly comprising a first slave sleeve, wherein the first slave activatable stimulation assembly activates responsive to activation of the first master stimulation assembly, wherein activation of the first slave activatable stimulation assembly provides a second route of fluid communication via one or more ports of the first slave stimulation assembly from the interior flow path of the completion string to an area adjacent the one or more ports of the first slave stimulation assembly and exterior to the completion string;
- a second master activatable stimulation assembly comprising a second master sleeve, the second master sleeve having a second seat;
- and
- a second slave activatable stimulation assembly comprising a second slave sleeve, wherein the second slave activatable stimulation assembly activates responsive to activation of the second master stimulation assembly.

A method of servicing a subterranean formation comprising:
- positioning a wellbore completion string within the wellbore, wherein the wellbore completion string comprises:
- a first master activatable stimulation assembly comprising a first master sleeve, the first master sleeve having a first seat;
- a first slave activatable stimulation assembly comprising a first slave sleeve, wherein the first master stimulation assembly and the first slave activatable stimulation assembly are positioned substantially adjacent to a first subterranean formation zone;
- a second master activatable stimulation assembly comprising a second master sleeve, the second master sleeve having a second seat;
- and
- a second slave activatable stimulation assembly comprising a second slave sleeve;
- activating the first master activatable stimulation assembly, wherein activating the first master activatable stimulation assembly comprises:
- passing a first obturating member through the wellbore completion string to engage the first seat;
- and applying a force to the first master sleeve via the first obturating member, wherein activation of the first master activatable stimulation assembly provides a first route of fluid communication via one or more ports of the first master activatable stimulation assembly from an interior flow path of the completion string to an area adjacent the one or more ports of the first master activatable stimulation assembly and exterior to the completion string, wherein the first slave activatable stimulation assembly is activated responsive to activating the first master activatable stimulation assembly, wherein activation of the first slave activatable stimulation assembly provides a second route of fluid communication via one or more ports of the first slave stimulation assembly from the interior flow path of the completion string to an area adjacent the one or more ports of the first slave stimulation assembly and exterior to the completion string;
- and
- communication a stimulation fluid to the first subterranean formation zone via the first route of fluid communication and the second route of fluid communication.
