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.

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.
