Abstract

"The measurement of the rheological properties, consistency of viscosity and fluid type, necessary for system design calculations, has fallen behind the industrial applications for non-Newtonian fluids. In the petroleum industry in particular, the process of well flow stimulation known as Hydraulic Fracturing utilizes the properties of various non-Newtonian fluids to carry sand at high flow rates to the formation to be fractured. Other non-Newtonian fluids in the petroleum industry are Bentonite clay drilling fluids, whose unique gelling properties are helpful in suspending drill cuttings when the circulation of the fluid has ceased. In Newtonian liquids and gases the consistency is constant if the static pressure and temperature are fixed. For these substances the consistency is usually analogous to the viscosity. If the consistency of a liquid is not constant but is a function only of the shear stress, the substance is classified as a non-Newtonian liquid. A dilatant type of non-Newtonian liquid has the property of changing its volume when subjected to a change in its shape at constant pressure.

The lack of fundamental methods of measuring the rheological properties of the non-Newtonian fluids is indicated in the accepted method of evaluating drilling fluids, which recommends a single viscosity determination of fluid from a flow system. Other methods of measuring viscosity are restricted to instruments designed for a specific range and type of fluid. Rheological measurements based on specific ranges of flow and individual fluids would not be universal in their application and their use could lead to erroneous results unless care is exercised in selecting the correct method for the fluid under investigation….

The method proposed by Metzner and Reed is not dependent on the type of fluid or viscosimeter and is theoretically rigorous in the laminar-flow region. However, a restriction to this method is the necessity that the consistency of the fluid must be a function only of the shear stress. Fluids whose consistency is a function of the shear stress and also the time of duration of shear.stress (thixotropic fluids) cannot be included in this analysis"--Introduction, pages 1-2

"This investigation is to extend the correlation of Netzner and Reed to include a dilatant type non-Newtonian starch suspension in water in the laminar-flow region using a pipe-line type viscosimeter”--Purpose of Investigation, page 5.
