ABSTRACT:
Apparatus is provided for collecting a plurality of samples of fluids in earth formations traversed by a well bore. The sampling apparatus includes an elongated body member adapted to carry a telescopically extensible and retractible fluid admitting probe which is selectively placed in sealing engagement with potentially producible earth formations. The fluid admitting probe has a central passage in fluid communication with a first fluid sample chamber and a plurality of outer passages which are selectively communicated with formation fluid sample storage chambers within the body member.
