ABSTRACT:
A signal repeater, a system utilizing one or more signal repeaters, and a method for detecting a transient disturbance in the surface charge on drill pipe, which system, apparatus and method are collectively used to transfer data from deep-well and high-conductivity formation subterranean environments to a point nearer to the surface. The signal repeater comprises a housing that is securably mountable to the interior of a pipe-string disposed in a wellbore, which repeater receives and stores electrical signals for resending at an appropriate time.
