Effective Viscosity Management in Asphalt and Lubrication Oils
There are more than 700 refineries worldwide, with roughly 82 million barrels of oil produced per day. Viscosity is one on the most critical measures of product quality for virtually every refinery product.
New developments in viscosity measurement are enabling refineries significant improvements in production quality, cost and output.

High Speed, Small Sample Rheometric Screening Using the Cambridge Viscosity Viscometer
Summary: Characterizing a fluid’s rheology rapidly while using only a small amount of fluid (<2mL) is highly advantageous in many applications, but historically impossible in most instances. In this paper, Cambridge Viscosity demonstrates that accurate, rapid, rheometric characterization with a small amount of fluid is now possible using electromagnetic viscometer technology.

Foamy Oil PVT and Rheology Measurements
Nasser Albartamani, John Ratulowskim DB Robinson Research Ltd., Edmonton, Canada S.M. Farouq Ali, B. Lepski of Alberta
Presented at The 2nd International Conference on Petroleum and Gas Phase Behaviour and Fouling Copenhagen, Denmark, August 27-31, 2000
Summary: “Foamy oil” phenomenon is associated with primary cold production, a non-thermal recovery process, from heavy-oil reservoirs producing under solution-gas drive mechanism. The “foamy oil” hypothesis used to explain the unusually high production is still much debated.
This paper describes the results of a study in which a series of PVT and viscosity measurements runs were carried out under different conditions to investigate and better understand foamy oil behavior. Viscosity was measured using three different viscometers, Cambridge Electromagnetic (CEV), a JEFRI capillary and Haake Rotovisco RV2 viscometer.

Using In-process Viscometry Measurements to Predict Prepolymer Molecular Weight and to Control the Molecular Weight of Polyurethanes
Richard J. Czarnecki and Mark J. Lindsey, Sun Chemical Corporation, Daniel J. Carlick Technical Center, Carlstadt, NJ 07072
Summary: Polyurethanes, which are prepared by the reaction of an isocyanate with a polyol, are commonly employed in a broad range of applications such as paints and inks. To create a polyurethane with the physical properties and performance characteristics required for a specific application, the synthetic chemist must closely monitor the progress of the synthetic reaction.
In this paper, the authors describe a series of experiments in which in-process viscometry was used to accurately and easily monitor the synthesis of an experimental polyurethane/urea prepolymer.
