Systems, assemblies and processes for controlling tools in a well bore
First Claim
1. A process comprising;
- configuring a plurality of signal devices each with a unique signal for conveyance downhole;
configuring a plurality of tools to each correspondingly receive one of the unique signals of the signal devices;
positioning the tools and a line downhole in a well penetrating a subterranean environs, said tools configured to be operated, after being positioned in the well, in response to the unique signals of the corresponding signal devices conveyed downhole;
conveying the configured signal devices downhole with fluid in the line in any first desired sequence of at least two or more of said configured tools at spaced apart locations along the well penetrating the subterranean environs;
opening, in response to the configured signal devices, sliding sleeves of the at least two or more of said configured tools by moving the sliding sleeves with the fluid in the line; and
fracturing the subterranean environs using the at least two or more of said configured tools operated in the any first desired sequence at the spaced apart locations along the well penetrating the subterranean environs, said tools being used in and remaining in the well during said fracturing.

Abstract
A dedicated hydraulic line for transmission of a signal device capable of generating one or more unique signals to one or more tools within a subterranean well. Each tool can be equipped with a reader device for receiving signals from and transmitting signals to the signal device. Each reader device can control operation of the tool associated therewith if the reader device is programmed to respond to signals received from the signal device. Hydraulic fluid used to operate the tool can be conveyed via the dedicated hydraulic line or a separate hydraulic line. A separate hydraulic line can be used to reset the tool. Where the tools include sliding sleeves, the tools can be used to hydraulically fracture subterranean environs at spaced apart locations along a well bore in any desired sequence and without removing the tools from the well during the fracturing process.
