Buckley-Leverett model was applied to evalute the effectiveness of the recovery method after the injected fluid breakthrough. Due to the high oil viscosity, the displacement for water flooding is unfavarable...

This workflow will allow a number of strategies to be studied, such as the impact of well types, well placement, well lengths, FCDs and polymer viscosities. The impact of polymer viscosity reduction in an injector well with FCDs is of particular...

... As it is shown in Figure 1 , the experimental investigations on a pore-throat pair show that the effect of viscosity and IFT on the amount of residual trapping is negligible and the only significant role is played by the contact angle ( Wardlaw 1982 ). Here, the main objective is to provide...

... and oil. If oil viscosity at reservoir temperature is low enough to allow primary production; it is feasible to develop heavy oil fields using horizontal wells and high volume lift pumps. However, operators have to prepare to treat and dispose large volumes of produced water. Other reservoirs with higher...

...% of the reserve. This low extraction yield mainly stems from the high viscosities of bitumen. Because the flow resistance of high viscosity crudes can be reduced by increasing the temperature of the reservoirs, extraction of these resources can be accomplished effectively with the application of thermal recovery...

... temperature is low (100°F) so bitumen viscosity is high (>100.000cp). In addition, oil saturation could be lower than is the standard for commercial projects in some areas. A reservoir characterization was done using data from 18 wells. Information from basic and special logs, routine and special core...

... Abstract In-situ formation of water-in-oil emulsions in crude oil is one of the severe problems encountered during the production phase of oil wells. These in-situ emulsions produce crude oil viscosities that are much higher than the viscosities of native crude oil. It is well known...
