Abstract
A method for evaluating a multiphase oilfield fluid includes blending a first sample of the fluid with a viscosity modifying agent to transform the sample into a paste; making a first XRF measurement of the paste to estimate an elemental composition of the fluid; making a calcimetry measurement of a second sample of the fluid to estimate a total carbonate concentration of the fluid and to obtain an acidified second sample; separating the acidified second sample to obtain an acidified brine; making a second XRF measurement of the acidified brine to estimate an elemental composition of the acidified brine; and determining an elemental composition of a solid phase of the multiphase oilfield fluid from the elemental composition of the acidified brine and the elemental composition of the multiphase oilfield fluid.
