... Abstract This paper presents the results of several series of laboratory tests evaluating the performance of polymer flooding for heavy oils. The effects of oil viscosity, polymer concentration, displacement velocity, and rock permeability have been studied and results are presented. Improved...

... investigation, we included the impact from certain heavy oil fluid property uncertainties, including dead oil viscosity, live oil viscosity and saturation pressure (or the initial gas-oil ratio, GOR). The reservoir simulations were performed for case studies with an API 9 reservoir fluid and geology similar...

... (the Weyburn and Midale fields are good examples for this case) in this paper. Proper design of this process is essential to maximize both the amount of CO 2 sequestered and oil recovered. In this cooptimization process, miscibility, oil viscosity, matrix properties (permeability, porosity, pore...

... Abstract Many countries in the world contain significant heavy oil deposits. In reservoirs with viscosity over several hundred mPa?s, waterflooding is not expected to be successful due to the extremely high oil viscosity. In many smaller, thinner reservoirs or reservoirs at the conclusion...

... Abstract A key parameter in a CO 2 flooding process is the CO 2 solubility; for, it contributes to oil viscosity reduction and oil swelling, which together, in turn, enhance the oil mobility and oil relative permeability. Often CO 2 solubility and the other CO 2 -oil physical properties...

Abstract Having knowledge of oil viscosity variation within reservoirs would be of considerable benefit when producing from heavy oil fields. Previous work has...

Based on the history matching...

... to the heavy oil group to operate. Emphasis on an oil-gravity-based definition of heavy oil is convenient, but unfortunate, as it de-emphasizes oil viscosity even though viscosity has repeatedly been shown to be a controlling parameter in numerical simulation runs. Aversion to a viscosity-based-definition...

The variables examined were: permeability ratio, oil viscosity, relative waterto- oil layer thickness, polymer concentration, injection rate and injection point, as well as the effect of vertical and horizontal injection...

Prediction of in situ viscosity with a logging tool can be benefitial in reservoir characterization and exploitation design. Low field NMR is a technology that has...

... Abstract Heavy oil viscosity is one of the few criteria available to help predict if cold production will give economic rates, or if thermal processes will be required to reduce the oil viscosity to achieve the required rates. If cold production is selected, viscosity is again used to help...

... Abstract Crude oil viscosity is an important physical property that controls and influences the flow of oil through porous media and pipelines. Hence, it is the basis of many reservoir engineering and production system calculations. In the crude oil recovery and processing, viscosity...

Another pitfall with viscosity correlations may occur when tuning the model entirely to stabilized oil viscosity data. In this situation live oil and gas viscosity predictions from the correlationcan...

.... These techniques have been used in studies of miscible flooding of light and medium oil8. The main difference here is that whereas miscibility is the focus for light and medium oils, viscosity reduction is the key to recovery of heavy oils. OBJECTIVES The objective of this investigation was to study compositional...
