The Darcy equation, including Brinkman term to account for the viscous effects, is used as the momentum equation. The model consists of two...

... computer). Several tests can be conducted in a single day, travel time included. The mass balance theory and relevant equations behind these tests are developed and explained with emphasis on the practical aspects. Test procedures are described with step by step detail in field examples. One...

... in the system. The microbubble capture and retention due to the presence of asphaltenes make the bubble release time much longer than when the asphaltenes are absent. This phenomenon has not been accounted for in the past. A new equation of state is generated that satisfies the PVT data for various asphaltene...

... the solvent residence time at each producer and the corresponding minimum bank thickness needed to maintain miscibility. The 1-D diffusion equation coupled with miscibility data was used to calculate the required bank thickness and a full field 2-D streamline model was used to predict the solvent residence...

... Abstract Measured fluid properties from four reservoirs are used to compare property prediction results using an equation of state (EOS) method and different PVT correlations available in the literature. These fluid properties include oil bubble point pressure, oil formation volume factor...
