Abstract: A large slot flow apparatus for
investigating hydraulic-fracturing fluid flow and proppant
transport phenomena has been installed at the University of
Oklahoma. The apparatus weighs 38 tons, has an adjustable
width flow channel that is 9.3 ft high, and includes
capabilities for investigating leakoff phenomena and
observing proppant transport. Operating conditions are
pressures to 1200 psi and temperatures to 250 degrees F.
Initial tests, with a Newtonian fluid and with a 60 lb/Mgal
hydroxypropyl guar (HPG) solution, show that all aspects of
the apparatus and associated instrumentation needed to
characterize the flow behavior of these fluids are working
satisfactorily.
