Variable density problems are suitable test-cases for multi-physics codes, as the interaction between flow and transport processes is a characteristic of the observed phenomena. This contribution focuses on density-driven flow benchmarks in porous media. Here FEMLAB® results are shown for the Henry model concerning stationary saltwater intrusion, and the Elder heat convection experiment in a ...
Nearwell Bore Pressure Transient Simulation with Geomechanical Deformation for Formation Evaluation in Weak Reservoirs

Geomechanics is valuable to account the rock deformations due to pore pressure and temperature changes resulting from production and fluid injection. We have used the FEMLAB 3.1 earth science module’s coupled geomechanical-fluid flow model to test its application to near wellbore pressure transient analysis. The new feature in FEMLAB 3.1 enables to couple geomechanical and fluid flow models ...

A Normal Mode Analysis (NMA) of the Chesapeake Bay was performed using Dirichlet boundary conditions and FEMLAB. The lowest 100 eigenstates were calculated and compared to a finite difference solution. Based on the normal modes derived numerically, surface current vector fields can be calculated. The vector fields of the Chesapeake Bay provide tools for the solution of problems such as the ...

Thermal anomalies indicating elevated temperatures often are present in producing hydrocarbon fields. This paper discusses precision temperature logs obtained over a salt dome in the Bayou Bleu hydrocarbon field in southwest Lousiana, and presents a 3-D thermal-fluid model of the dome constrained by these types of logs. The numerical model in which both an enhanced thermal conductivity ...

The usage of geothermal heat by the means of railway infrastructure is a relatively new method to tap renewable energy sources. A research project at the Department of Railway Engineering, Transport Economics and Ropeways at Vienna University of Technology in cooperation with the Department of Soil Mechanics and Geotechnical Enginering and the Atlas Copco MAI Ltd. deals with the development of ...

Electric well logging was the first logging method used below ground in boreholes by the petroleum industry. Of all the rock parameters measured by logging tools, the electrical resistivity is of particular importance. Resistivity measurements are essential for determining the relative amount of hydrocarbons in a formation.

Theoretical and experimental studies on the rotation of rigid inclusions under simple shear flow have typically considered infinite width shear zones and perfect attachment of inclusion to the matrix. According to these models, during progressive simple shear a coherent object would continuously rotate synthetically, which is not the case in many natural ductile shear zones. In this work we ...

The assurance of mass consistency in constructing 3-D atmospheric velocity fields is important when developing accurate numerical simulations. The implementation of a mass consistent wind field is typically undertaken using available meteorological data obtained from instrumented towers and remote sensors. In this study, two methods are presented and compared for constructing 3-D mass ...
Flow Diversion around Elliptical Inhomogeneities Modeled with FEMLAB and the Analytic Element Method

Sudden transitions in hydraulic properties in natural porous media systems associated with deposited inhomogeneities can lead to large diversions flow around or convergence of flow toward the inhomogeneity. Modeling of these features within large unsaturated zones containing such inhomogeneities is challenging because of the need for refined discretization near the boundary of the ...

The method to derive upscaled expressions for the dispersion coefficients for reactive flow in a porous medium uses a periodic unit cell (PUC), which consists for instance of a spherical grain in a cube, but nothing prohibits defining more complex PUC's. Homogenization leads to a coupled system of equations where the flow is described by Stokes equation and the concentration fluctuation is ...
