Abstract

A wellbore servicing tool comprising a housing comprising one or more ports and generally defining a flow passage, an actuator disposed within the housing, a magnetic signature system (MSS) comprising a magnetic sensor in signal communication with an electronic circuit disposed within the housing and coupled to the actuator, and a sleeve slidably positioned within the housing and transitional from a first position to a second position, wherein, the sleeve is allowed to transition from the first position to the second position upon actuation of the actuator, and wherein the actuator is actuated upon recognition of a predetermined quantity of predetermined magnetic pulse signatures via the MSS.

First claim

What is claimed is:

1. A wellbore servicing method comprising:
positioning a tubular string comprising a well tool comprising a magnetic signature system, wherein the well tool is configured to either allow a route of fluid communication between the exterior of the well tool and an axial flowbore of the well tool or to prevent the route of fluid communication between the exterior of the well tool and the axial flowbore of the well tool;
introducing a magnetic device to the axial flowbore of the well tool,
wherein the magnetic device is configured to generate a modulated digital signal, a data packet, and an analog waveform, and
wherein the magnetic device is configured to provide a variable magnetic polarity; and

actuating the well tool in recognition of a predetermined quantity of predetermined magnetic signatures via the magnetic signature system, wherein the well tool is reconfigured to alter the route of fluid communication between the exterior of the well tool and the axial flowbore of the well tool.

2. The wellbore servicing method of claim 1 , wherein actuating the tool comprises allowing fluid communication via the route of fluid communication where the fluid communication was previously prevented via the route of fluid communication.

3. The wellbore servicing method of claim 1 , wherein actuating the tool comprises preventing fluid communication via the route of fluid communication where the fluid communication was previously allowed via the route of fluid communication.

4. The wellbore servicing method of claim 1 , wherein actuating the well tool in recognition of a predetermined quantity of predetermined magnetic signatures via the magnetic signature system further comprises transitioning the well tool from a first configuration to a second configuration.

5. The wellbore servicing method of claim 1 , wherein the well tool is not responsive to the magnetic signal, wherein the magnetic signal does not comprise the predetermined quantity of predetermined magnetic pulse signatures.
