Abstract: Aqueous liquid which has been in contact with a subterranean geological formation, especially a hydrocarbon reservoir, is examined in order to detect or measure viscosifying polymer therein, by flowing a sample of the liquid through a constriction thereby causing extensional flow and alignment of any polymer molecules with the flow, and examining the solution for birefringence of aligned polymer molecules. The amount of birefringence is determined from intensity of light which has passed through the solution relative to intensity of the light source.

Abstract: A system and method for measuring physical properties of non-Newtonian fluids, such as fluids containing dispersed solid particulate material and having a yield stress. A fluid resistance member is moved through the non-Newtonian fluid sufficiently slowly that viscous drag on the member is negligible and fluid resistance is essentially due to the yield stress of the fluid. The torque required to maintain the movement of the member through the fluid is measured, and at least one physical property, other than apparent viscosity of the fluid, is determined by employing a known relationship between the measured torque and the physical property of interest.
