1. A method for estimating an elemental composition of a multiphase oilfield fluid, the method comprising:
obtaining a sample of the multiphase oilfield fluid;
blending the sample with a viscosity modifying agent to transform the sample into a higher viscosity paste;
introducing the higher viscosity paste into a chamber of an x-ray fluorescence (XRF) apparatus;
using the XRF apparatus to make an XRF measurement of the higher viscosity paste; and
evaluating the XRF measurement to estimate an elemental composition of the obtained multiphase oilfield fluid.
