... to transport high viscous oil. The third method involves applying a technology in the extraction process to reduce the viscosity of heavy oil, and in-situ upgrade the heavy oil up to sales specifications with a consideration of long distance between fields. This study concludes that a conceptual engineering...

... viscosity, the displacement for water flooding is unfavarable. However, the polymer addition improves the viscosity ratio injected/displaced fluids, making the displacement front more sharp. The fractional flow curves showed that the polymer flooding reduces the amount of the remaining oil more than water...

The PVT behavior was found to be qualitatively similar to that of the samples examined in the past except for the viscosity which seems to have increased over...

... Abstract Rubiales and Quifa are the Colombia's major heavy oilfields (oil gravity ranges from 11.3 to 14.4° API) with a current oil production of more than 260 MSTB with an oil viscosity ranges from 370 to 730 centipoises. Horizontal well technology is used to drill through unconsolidated...

The ESP systems for heavy oil are used in the industry especially in offshore fields for handling high flows in confined spaces...

... Most bitumen produced in Alberta is transported through commercial pipelines to downstream refineries. Pipeline operators set limits for density and viscosity -- so the bitumen must be diluted with lighter hydrocarbon liquids to meet these limits. For example, Enbridge has a density specification...
