Methods of servicing a well bore using self-activating downhole tool
First Claim
1. A method of servicing a well bore comprising:
- deploying into the well bore a zonal isolation device operable to self-set at a sensed location;
self-setting the zonal isolation device to hold at the sensed location without receiving command communications from the surface;
deploying a perforating gun into the well bore after the device is set;
firing the gun to form a set of perforations; and
pumping a servicing fluid down the well bore to a location above the set device;
wherein;
the zonal isolation device is deployed along at least a partial length of the well bore via an external force;
the device seals the well bore at the sensed location;
the servicing fluid is a fracturing fluid;
the fracturing fluid enters and fractures a formation via the set of perforations in the well bore; and
wherein deployment of the gun is stopped when a spacing component engages both the set device and the perforating gun.

Abstract
A method of servicing a well bore comprises deploying into the well bore a zonal isolation device operable to self-set at a sensed location, and self-setting the zonal isolation device to hold at the sensed location without receiving command communications from the surface, wherein the zonal isolation device is deployed along at least a partial length of the well bore via an external force. Another method of servicing comprises deploying into the well bore a tool operable to self-activate at one or more locations, and self-navigating the tool to determine the one or more locations without receiving communications from the surface, wherein the tool is moved along at least a partial length of the well bore via an external force.
