... 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...

... pressure and solid displacement are chosen as primary variables. For the finite volume method, the fluid pressure is located at the cell center. For the finite element method, the displacement vector is computed at each nodes. After the time and space discretization, an example of the coupled equations...

... that such an approxiamation, i.e. irrotational displacement must be lifted for a general coupled reservoir-geomechanics model so that the deviatoric far-field stress effect on pore pressure can be captured [ Carter and Booker, 1982 , Detournay and Cheng, 1988 ]. Abstract The effectiveness of a hydraulic fracturing...

... approach with an extended Petrov-Galerkin method in which the weighting function consistent with the shape function in pore pressures is implemented. A general formulation with four pore pressures and one bulk displacement for the primary variables are presented. Results from an approximated formulation...

... 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...

.... 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 injection and that detailed representation of small...

... 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...

Vertical tertiary WAG (hydrocarbon injection gas and brine). Vertical tertiary gas flood (CO 2 injection). A repeat of the above three displacement mechanisms...

... the validity of the EOS tuning. Using the compositional simulation of slim tube displacements, minimum miscibility pressure (MMP) was estimated for both oils and different injection gases. Although a 9 component scheme is adequate for reservoir performance purposes, engineering of surface facilities requires...

The main issues that could be addressed using laboratory technical evaluation are covered including PVT properties of different CO2-Oil mixtures, effect of Rock Pore Structure on CO2 Miscible Displacment, effect of WAG and Wettability on CO2-EOR Flooding, assessement...

..., initial pressure and the distribution of current pressure. The next phase of recovery might be a waterflood. Here, oil saturation may be reduced to a residual oil saturation in the swept zone. The water also displaces the mobile gas phase leaving trapped gas saturation and any repressurization causes...

Immiscible displacement, miscible displacement, pressure maintenance, gravity enhancement and driving agent for miscible slug. In miscible displacement nitrogen can displace oil efficiently by developing a miscible bank...
