ABSTRACT:
A fluid sampling device particularly suited for downhole applications is disclosed. The device has a tubular housing with a retractable sample tube nested within. The housing and sample tube have generally pointed leading edges to facilitate embedment into the formation to a sufficient depth to isolate the fluid sample to be obtained from well fluids. Having embedded the apparatus a sufficient depth, a downward force is applied to the sample tube, severing its prior restraint to the housing and extending the sample tube into the formation. Openings in the sample tube allow the fluid to come through it, whereupon it is conducted to the surface. Removal of the downward forces applied to the sample tube allows a biasing mechanism to act on the sample tube to retract it into the housing prior to the removal of the housing from the formation.
