Abstract

See full text

According to aspects of the present disclosure, systems and methods for measuring fluid resistivity are described herein. An example system may include a non-conductive tube. The non-conductive tube may be filled with a fluid, such as a formation fluid or drilling fluid, whose resistivity needs to be determined. A transmitter may be disposed around an outer surface of the non-conductive tube. A first receiver may be disposed around the outer surface of the non-conductive tube, and a second receiver may be positioned within a bore of the non-conductive tube. The transmitter may generate a primary electromagnetic field in a fluid within the tube, which may in turn generate an eddy current and a secondary electromagnetic field. The first and second receivers may be used to identify the eddy current and the resistivity of the fluid.
