1. A method of determining the quantity of free immiscible fluid dispersed as droplet particles in the presence of oil having solid particles suspended therein, said method comprising the steps of optically determining the combined particle size distribution of substantially all particles in a sample of said oil, mixing said oil sample with a masking fluid that is soluble with said oil and said immiscible fluid, optically determining the size distribution of substantially all particles remaining in said oil sample after mixing with said masking fluid, and deducting the remaining particle size distribution from the combined particle size distribution to conclude a quantity of free immiscible fluid initially present in said oil sample.
