Understanding the rock structure at nano to micro scale is of growing importance in geology, oil and gas, and hydrology. New approaches that relies on a variety of high resolution 3D imaging techniques offered tremendous potential. These new approaches, in the meanwhile, introduce significant new challenges. Starting from digital imaging data, the paper introduces an image-to-simulation ...
Full Coupling of Flow, Thermal and Mechanical Effects in COMSOL Multiphysics® for Simulation of Enhanced Geothermal Reservoirs
D. Sijacic, P. Fokker
TNO, Utrecht, The Netherlands
The effective modeling of enhanced geothermal systems (EGS) requires the coupling of geomechanics, fluid flow and thermal processes. An understanding of the complete system with these coupled processes is vital, not just for reservoir stimulation targeted at enhancing reservoir performance, but also for the understanding, prediction and prevention of induced seismicity. Thermal effects however ...

Geothermal heat pumps use the earth as a heat source and sink via a ground heat exchanger (GHX) that consists of a network of buried heat exchange pipes, which can either be installed in vertical boreholes or in shallow horizontal trenches or excavations. The main goal in GHX design is to determine the minimum length of pipe needed to provide adequate fluid temperatures to heat pumps over their ...

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 ...

The detection, characterization, and classification of underground environmental hazardous objects [mines, IEDs, and other unexploded military hardware] is a worldwide problem that needs urgent attention and solution. While electromagnetic sensor technologies have been applied to identify these hazards, increasingly low dielectric contrast between newer, sophisticated landmines, and complex ...

The "Lithic Hypar" research is based on the mechanical analysis of an innovative reinforced stone's structure, architecturally designed by Prof. Fallacara, University of Bari (Italy): the headquarters entrance portal of the French company SNBR (Société Nouvelle Batiment Régional) located in Troyes (France), the realization of which is planned for October 2015. The main idea of this lithic ...
The Use of COMSOL Multiphysics® Software to Explore Flooding and Rising Dampness Problems Related to Cultural Heritage

In The Netherlands rising dampness problems due to flooding of rivers and high groundwater levels form an essential treat for monumental buildings and heritage. A number of cases exists where rising dampness problems lead to the deterioration of wall finishes but also of valuable wall paintings in churches and castles. To explore the problem and to look for solutions like drying regimes, ...
Fracture-Matrix Flow Partitioning and Cross Flow: Numerical Modeling of Laboratory Fractured Core Flood

The contrast between hydro-mechanical behavior of the rock matrix and fracture network systems results in flow partitioning between fracture and matrix systems which is affected by the In-situ stress regime. Fracture flow, Darcy law and free and porous media flow physics interfaces of COMSOL were used in simulating a fractured core flooding test to achieve a better understanding of flow ...
Numerical Simulation: Field Scale Fluid Injection to a Porous Layer in Relevance to CO₂ Geological Storage

CO₂ geological storage can help to provide a “bridge” from a fossil-fuel dependent system to a more diversified energy portfolio. Pressure monitoring for an injection zone (IZ) and an above-zone monitoring interval (AZMI) has been under operation at a field-scale CO₂ injection site, Cranfield, MS. Recorded pressure data in the AZMI revealed a certain amount of increase with no evidence of direct ...
