... to generate opportunities at well and field level; this methodology was used to analyze the impact of fractures in the reservoir performance and management. The complexity of the geology on areas near a graben system (structure at center of the field with biggest vertical displacement) was suspected to cause...

... ρ b denotes bulk density, ρ f represents fluid density, ρ s stands for density of solid phase, and u is the displacement vector. To couple the flow and mechanics equations, a relationship between stress and strain need to be built ( Biot, 1941 ; Coussy, 1995 ; Borja, 2006 ). According...

... Abstract A dual porosity formulations coupled geomechanics to two-phase fluid Flow in fractured reservoirs are developed and a Petrov-Galerkin finite element method is utilized. Formulations for saturation, with a time variable only, is incorporated with the displacement and pore pressures...

... Abstract The physics of multi-phase displacement processes in the individual pores of a connected pore-network of a rock ultimately controls how oil, gas and water move in reservoir rocks and how readily they can be produced. These pore scale processes, including piston-like displacement, snap...

... they are influenced by matrix and fracture heterogeneities. The results show up to 7% incremental recovery by gas injection compared to secondary recovery due to the contact of un-swept zones and improved hydrocarbon displacement. We show how gas channelling along high permeability layers is mitigated by WAG...

... layers significantly reduce the performance of the gas-oil gravity drainage process for immiscible gas injection, while increasing the recoveries substantially for multiple- and first-contact miscible gas injection cases. upstream oil & gas miscibility condition gas injection displacement...

... Abstract This paper presents an experimental and numerical study to investigate the effects of viscous, capillary, and gravity forces on compositional two-phase displacements in layered porous media. We use glass bead packs of different sizes to construct a quasi 2-D porous medium of three...

... Abstract Considerations for better ultimate oil recovery and maintaining plateau production beyond the current expectations depend on appropriate EOR methods. Laboratory core floods provide both the recovery characteristics and validity of the microscopic displacements in 1D, and hence...

The tuned EOS was then used on a 1 D reservoir simulation compositional model to match the available slim tube experiments, to verify the validity of the EOS tuning. Using the compositional simulation of slim tube displacements...
