Diffusivity in Heavy Oils

SPE International Thermal Operations and Heavy Oil Symposium, 2005
Abstract Molecular diffusion of gases in heavy oils is one of the most important physical parameter governing cold production processes such as solution gas drive or Vapex. Indeed, the way bubbles are able to grow by diffusion will have a direct impact on gas mobilization and consequently on oil recovery.

Rheology of Heavy Oil Emulsions

Proceedings of SPE/PS-CIM/CHOA International Thermal Operations and Heavy Oil Symposium, 2005
Abstract Water is invariably produced with crude oil. If there is enough shear force when crude oil and produced water flow through the production path, stable emulsions may be formed. This scenario may particularly be present during the production of heavy oils where steam is used to reduce the viscosity of heavy oil or in cases where ...

Rheological Properties of Heavy Oils and Heavy Oil Emulsions

Energy Sources, 1996
In this study, we investigated the effects of a number of process variables such as shear rate, measurement temperature, pressure, the influence of pretreatment, and the role of various amounts of added water on the rheology of the resulting heavy oil or the emulsion.

Interaction of Heavy Crude Oil and Nanoparticles for Heavy Oil Upgrading

2020
The relevance of nanotechnology in the field of energy resources has been growing at a swift pace. The term ‘catalyst’ has a whole new outlook since the foundation of nanomaterials in process industries. Nanocatalysts, in general, play a vital role in the improvement of resource handling and process efficiency.

In Situ Upgrading of Heavy Oil in a Solvent-Based Heavy Oil Recovery Process

Journal of Canadian Petroleum Technology, 2005
Abstract In this paper, a series of laboratory experiments are conducted under reservoir conditions to quantify the in situ upgrading of heavy oil due to the solvent dissolution and asphaltene precipitation by using a pure solvent (propane) and a solvent mixture (70 mol% methane + 25 mol% propane + 3.5 mol% n-butane
