A method for sampling a downhole formation fluid includes pumping formation fluid into the flowline of a downhole sampling tool While pumping, a saturation pressure of the formation fluid is measured. The pumping rate is adjusted such that the fluid pressure in the flowline remains above a threshold saturation pressure.

Flowline saturation pressure measurements

A method for sampling a downhole formation fluid includes pumping formation fluid into the flowline of a downhole sampling tool, measuring a saturation pressure of the formation fluid in the flowline while pumping, and adjusting the pumping rate such that the fluid pressure in the flowline remains within a predetermined threshold above the measured saturation pressure.

A technique enables construction of a simplified inflatable packer. An inflatable packer is constructed with a packer reinforcement layer having at least one fiber layer. The fiber layers provide both mechanical and anti-extrusion qualities in a relatively simple and small package. Depending on the desired application, the inflatable packer also comprises an inner bladder layer and other potential layers, such as an outer seal layer. Mechanical extremities are used to secure longitudinal ends of the various packer layers, including the packer reinforcement layer.
