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, ...

The objective of this study is to acquire a full characterization of a hyper-elastic material. The process is realized by performing a Dynamic Mechanical Analysis (DMA) with a viscoelastic material, which is extended by image processing algorithms in order to measure the changing distance of two dots in the direction of contraction. Due to the non-linear behavior of the material, the model ...

We examine the poroelastics mode, which couples hydraulics and mechanics by some basic benchmarks. For cases with analytical solutions we check the accuracy for changing meshes and calculate the convergence rate.

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 ...

Accurate estimation of rock permeability and porosity play a crucial role in the evaluation of oil and gas reservoirs. This evaluation is, however, challenging in tight formations such as shale due to the slow transition of fluid in such formations with extremely-low permeability. To overcome the long experimental time of conventional technique for permeability measurement (steady-state method), ...

The Solargeotherm project is assessing the possibility of using vertical geothermal probes drilled into a rock mass (bedrock) for storing the thermal energy produced by solar panels and later releasing it. The research project relies on the installation of an experimental system and the use of heat transfer models. The underground device, set up entirely in Paleozoic schist (greenish grey banded ...

Direct numerical simulation of single- and two-phase flow in real pore systems is addressed in our paper. The X–ray computed micro-tomography technique has been applied first to reconstruct in details a real pore space of a subcentimetric sample. Making use of dedicated software (ScanIP) the generated porous medium images has been processed to build a 3D pore space geometry. Finally, based on ...

Injection conditions of CO2 at the wellhead may play a major role on the flow behavior through the wellbore. The density and the injection rate reached at the bottomhole are key factors affecting the performance and efficiency of CO2 geological storage. In this work, a model of non-isothermal flow of CO2 in injection wells is developed using COMSOL Multiphysics® software and used to assess ...

In underground mining operations, the mined-out spaces (called stopes) need to be backfilled to maintain the stability of surrounding rock mass and increase the ore recovery. Cemented paste backfill (CPB), a mixture of water, binder, and tailings, has been intensively utilized in underground mining operations to fill the stopes. After preparation, the fresh CPB is transported into stopes via ...

In this study, based on a bank protection structure engineering at Yangtze River, a 2D water-soil coupling model is established, in which the influence of water level fluctuation on groundwater seepage and soil shear strength is considered. According to the water level measured data of the Yangtze River, the displacement of bank protection structure is calculated and the structural deformation ...
