ABSTRACT:
A formation evaluation tool positionable in a wellbore penetrating a subterranean formation is provided. The formation evaluation tool includes a cooling system adapted to pass a cooling fluid near electronics in the formation evaluation tool whereby heat is dissipated therefrom, the electronics has at least one gauge, a fluid communication device having an inlet adapted to receive the formation fluid and a flowline operatively connected to the fluid communication device and the gauge for placing the formation fluid in fluid communication therewith whereby properties of the formation fluid are determined. The formation evaluation tool may also be provided with a plurality of sample chambers operatively connected to the flowline for collecting at least a portion of the formation fluid and a pressure compensator in fluid communication with the wellbore and operatively connected to the plurality of sample chambers for applying pressure to the sample chambers whereby pressure is balanced therebetween.
