Hydrophobic meshes are a new, promising technique for the recovery of spilled oil in the ocean. They allow to recover and store oil, while filtering it from the surrounding water. They are clean, efficient and can be used in continuously. These meshes have one drawback, however: if they are submerged too deep under the water level, the high pressure will cause presence of water in the recovered ...

Relative permeability maps for steady-state two-phase flow in porous media, delivered by implementing the DeProF model  algorithm, were integrated within COMSOL Multiphysics® software  to resolve field-scale flows in porous media. The mechanistic model DeProF , predicts the relative permeability of oil and water in terms of the capillary number, Ca, the oil/water flowrate ratio, r, ...

Using a 1-D model of polymer displacement, we analyze the exergy (maximum attainable work) balance of viscosified water, e.g. with Arabic gum. The 1-D model shows the principle how such an analysis can be done. A comparison as to the displacement efficiency is made between three scenarios, i.e., (1) pure water injection, (2) constant polymer viscosified water injection and (3) polymer slug ...

Waterflooding is widely used in secondary oil recovery. The physics is described by the model of two-phase flow in porous media. The aim of the present work is to implement this model in COMSOL Multiphysics and to simulate the process of waterflooding. It is analyzed in two dimensions. We use layered reservoir in our study. The numerical implementation is validated, comparing with analytical ...

Wettability affects two-phase displacements in porous media by determining the microscopic distribution of fluids in pore spaces. The impact of wettability on transport properties at macro-scales has been widely addressed in literature; however a deeper understanding of wettability effects demands pore-level investigations which are still limited. In this paper, COMSOL Multiphysics® software ...

The efficiency and environmental impact of oil production become a principal challenge of energy producing companies. The improvement of existing and development of novel methods are often feasible within either a “new” physical framework (from the viewpoint of oil reservoir applications) or a non-trivial combination of “known” phenomena. Last fifty years the dedicated reservoir simulators have ...

THM (Thermo-Hydro-Mechanical) behavior of the reservoir during SAGD (Steam-Assistant-Gravity-Drainage) was studied through a proper constitutive modeling of the porous media. Specifically, a generalized density-stress-fabric dependent elasto-plastic model with stress-dilatancy and plastic damage as main ingredients was implemented into COMSOL Multiphysics®, to model geomechanical behavior during ...

In general, macroscopic two-phase flow in porous media is a mixture of connected and disconnected oil flow. The latter is expressed as ganglion dynamics and drop traffic flow, patterns observed experimentally in pore network models [1,2] and real porous media [3,4]. This characteristic was adversely not taken into account in previous modeling approaches. The mechanistic model DeProF , ...

Non-conventional hydrocarbon resources become more and more challenging object for energy producing companies throughout the world. Being already known and long-explored method, the electromagnetically (EM) assisted recovery constitutes a promising idea of technology for deposits of such a kind. COMSOL has been used recently for modeling the thermal multiphase flow through porous media in the ...

New geothermal energy sources hold promise for the future. Deep submarine geothermal energy related to hydrothermal vents is emerging in many places along the oceanic spreading centers. Shallow submarine geothermal systems are found near to continental platforms. We present the initial development of mathematical models to simulate the energy transport in submarine systems. A model for the ...
