A wellbore servicing system comprising a casing string disposed within a wellbore, a work string at least partially disposed within the casing string and having a wellbore servicing tool incorporated therein, wherein the wellbore servicing tool is selectively transitionable between a jetting configuration and a mixing configuration, wherein the wellbore servicing tool is configured to transition between the jetting configuration and the mixing configuration via contact between the wellbore servicing tool and the casing upon movement of the work string upwardly within the casing string, upon movement of the work string downwardly within the casing string, or by combinations thereof.

Wellbore servicing assemblies and methods of using the same

A pressure-balanced acoustic-signal-receiving apparatus and methods therefor. The apparatus may comprise a first housing, a first actuator, a second housing, and a second actuator. The first housing may comprise a fluid chamber, a passage connecting a first and second portion of the fluid chamber, a tubular-contact assembly, an isolating member within the fluid chamber and coupled to the assembly, an acoustic-signal receiver within the isolating member and coupled to the assembly, and a communication member coupled to the receiver. A method for receiving an acoustic signal generated within a wellbore may comprise receiving the acoustic signal with a tubular-contact assembly, sensing the acoustic signal with an acoustic-signal receiver positioned within a fluid chamber and coupled to the assembly, equilibrating fluid pressures in the first and second portions of the fluid chamber, and transmitting information generated by the acoustic-signal receiver through a communication member.

Acoustic reception

An apparatus for servicing a wellbore comprising a housing, high-pressure ports, high-volume ports, and a mandrel slidably positioned within the housing. The housing defines an axial flowbore and the mandrel defines a mandrel axial flowbore. The mandrel is alternatingly movable from a first position to a second position and to a third position. When the mandrel is in the second position, a route of fluid communication via the high-pressure ports is provided and a route of fluid communication via the high-volume ports is obstructed. When the mandrel is in the third position, a route of fluid communication via the high-volume ports is provided. The apparatus is transitionable from the second position to the third position without communicating an obturating member to the apparatus, without removing an obturating member from the apparatus, or combinations thereof.
