Abstract
Abstract An ultrasonic technique, based upon Rayieigh scattering, is described for calculating the size distributions (2–10μm dia.) of low concentrations of particles in water from the amplitude measurements of backscattered acoustic pulses. Results of the particle size distribution calculations agree well with the size distributions measured with a Coulter counter. This technique was applied to particle systems that had identical material properties and size distribution functions which decreased with increasing size. With further development, this method may provide valuable solids content and size distribution information in source waters that are injected during waterflood operations.
