Abstract
An apparatus for estimating an oil, water, and solids fraction of a drilling fluid includes a conduit containing the drilling fluid, an electromagnetic sensor in communication with the drilling fluid that senses a combined water and solids fraction, and at least one of a conductivity sensor or a density sensor, each in communication with the drilling fluid. The apparatus also includes a processing system determining the fraction of oil, water, and solids in the drilling fluid using the combined water and solid fraction and at least one of the conductivity value from the conductivity sensor or the density value from the density sensor and a controller coupled to the processing system, the controller having an output coupled to a drilling fluid additive control device controlling an additive to be added to the drilling fluid based on the fraction of oil, water, and solids of the drilling fluid.
