Patent ID: 7461547

Claim:
A downhole fluid sampling and characterization apparatus configured for operation downhole, within a borehole, comprising: a fluid sampling and analysis module, the fluid sampling and analysis module comprising: a flowline for fluids withdrawn from a formation to flow through the fluid sampling and analysis module downhole, within a borehole, the flowline having a first end for the fluids to enter and a second end for the fluids to exit the fluid sampling and analysis module; a first selectively operable device and a second selectively operable device structured and arranged with respect to the flowline for isolating a quantity of the fluids in a portion of the flowline between the first and second selectively operable device; and a pump unit integrated with the flowline for varying pressure and volume of the isolated fluids wherein the pump unit comprises a syringe-type pump; and at least one sensor connected to the portion of the flowline between the first and second selectively operable device for measuring parameters of interest downhole, within a borehole, relating to the fluids in the flowline.
