ABSTRACT:
A formation evaluation system for a subterranean formation penetrated by a wellbore. The formation evaluation system is provided with a downhole tool and a sensor. The downhole tool is positionable in the wellbore. The downhole tool has a downhole electromagnetic unit for communication with a surface electromagnetic unit. The sensor determines at least one wellsite parameter from the electromagnetic signal. The downhole tool and the surface electromagnetic unit are adapted to pass electromagnetic signals there between. The electromagnetic signals pass through the subterranean formation whereby the senor determines the at least one wellsite parameter from the electromagnetic signal.
