Abstract
A method for evaluating a multiphase drilling fluid includes receiving a sample of the multiphase drilling fluid and modifying the sample to enhance a separation of a first NMR peak corresponding to a first fluid phase component and a second NMR peak corresponding to a second fluid phase component. A nuclear magnetic resonance (NMR) measurement is made of the modified sample and evaluated to compute a property of the drilling fluid.
