Abstract
A method of a method of analyzing a fluid includes measuring a conductive flow of a fluid circulating through a borehole during a subterranean operation, the conductive flow indicative of an electrically conductive constituent of the fluid. The method also includes measuring a total flow of the fluid concurrently with the measuring of the conductive flow, and estimating a property of the fluid in real time during the subterranean operation based on the conductive flow and the total flow.
