Rheological characterization of fracturing fluids using laser anemometry
This work describes the use of a novel technique, laser doppler anemometry, to obtain information on fracturing fluid behavior. This technique permits measurement of the fluid velocity at any point in a flow system. By scanning across the flow geometry, it is possible to obtain the velocity profile, which is in turn related to the rheology of the fluid. At low shear rates, velocity profiles obtained for aqueous solutions of hydroxypropyl guar showed significant deviations from those calculated using known power law parameters. The immediate results of this work are of interest in proppant transport modelling, and correlate well with published data which show that apparent viscosities obtained from proppant settling velocities are lower than those obtained from power law parameters. 14 references.
