ABSTRACT:
A downhole drilling tool positionable in a wellbore penetrating a subterranean formation is provided. The tool includes a formation evaluation tool having fixed and retrievable portions. The fixed portion is operatively connected to a drill collar of the downhole tool. The fixed portion is for establishing fluid communication with a subterranean formation. The retrievable portion is fluidly connected to the fixed portion and retrievable therefrom to a surface location. The retrievable portion is for receiving a formation fluid from the subterranean formation.
