..., vugs, and fractures. Further karsting preferentially created vuggy layers in skeletal-rich wackestones and packstones, leading to bands of enhanced lateral permeability. Subsequent sea-level rise submerged the Rubble's erosional surface and led to the deposition of the Blue Shale, an effective...

..., modifying wettability and thus making it flow more easily. Relative permeability equations are key to be able to modelize the SAGD process and to determine the best optimization parameters (for a better energy efficiency and potentially reduce costs linked to this thermal EOR process). There are very few...

..., by the elimination of gas phase. In oil fields with little access to CO 2 , CWI can be an attractive EOR option ( Riazi et al. 2010 ). During SWAG injection gas mobility control is mainly achieved by the simultaneous flow of gas and water and reduced gas relative permeability compared to two-phase gas relative...

The sensitivity analysis results showed that the initial oil saturation, oil viscosity, porosity, and matrix permeability were the most important parameters affecting improved oil recovery when combined technology applied. The matrix permeability was the most important parameter...
