... on effective hole cleaning. It is assumed that liquid phase is the major contributor for cuttings transport, and gas phase is only influencing the bottom hole pressure. A mechanistic model is introduced for estimating the hydraulic behavior of gas-liquid mixture drilling fluids under different flow patterns...

... of propane and CO 2 with Athabasca bitumen are considered. Saturation pressures were measured in a PVT cell and the density and viscosity of the saturated liquid phase were determined at temperatures between 0 and 90 °C and pressures up to 5 MPa. Data are reported for CO 2 -bitumen, propane-bitumen...

... are reviewed and proposed whereby errors can be minimized. Recommended are multi-rate field sampling along with bottom-hole sampling, detailed analysis of produced liquid-phases and the importance of adhering to the parametric path followed in the field in order to develop representative fluids. Background...

... Abstract The paper presents experimental PVT data of reservoir fluid mixtures with API gravities ranging from 8 to 30. As can be seen from the presented data, heavy oils may under influence of gas injection split out an extra liquid phase, for which type of system a VLLE approach would...

... OF THERMODYNAMIC MODELING According to the thermodynamic equilibrium principle, the fugacity of component in the vapor phase, in the liquid phase and in the solid phase is equal when a system is under the thermodynamic equilibrium condition: S i L i V i fff == 1) Equation (1) equates the following two equations: L...
