ABSTRACT:
There is disclosed in the present specification a method and apparatus for use of a downhole formation multi-tester instrument in the characterization of formation fluids, including measurement of the conductivity of water, often in the presence of hydrocarbons under dynamic flow conditions and determining the hydrocarbon volume of the formation fluid. Utilizing a coaxial transmission line as a flow tube within the formation multi-tester instrument an electromagnetic wave is generated which propagates through the formation fluid in a transverse electromagnetic mode. Measurement of the phase shift and attenuation of the electromagnetic wave at points within the flow tube allow characterization of the fluid inside the cavity of the flow tube for dielectric constant and conductivity. Dielectric constant and conductivity can then be related to fluid conductivity and hydrocarbon volume.
