Aquifer Physics Modes for Hydrogeological Modeling – an Application of the COMSOL Physics Builder

E. Holzbecher[1]
[1]Georg-August Universität Göttingen, Göttingen, Germany

Although there are porous media and subsurface flow modes available in a toolbox of COMSOL Multiphysics®, some common requirements in hydrogeological models can not be easily accessed in the graphical user interface. Most crucially, there is no distinction between confined and unconfined situations for permeable layers, so called aquifers. Using the Physics Builder for such distinctions aquifer ...

Multiphysics Between Deep Geothermal Water Cycle, Surface Heat Exchanger Cycle and Geothermal Power Plant Cycle

L.W. Wong[1]
[1]International Centre for Geothermal Research, Helmholtz Centre Potsdam, GFZ German Research Centre For Geosciences, Telegrafenberg, Potsdam, Germany

Within the framework of Groß Schönebeck project in the North German Basin of Germany, multiphysics between deep geothermal reservoir, boreholes, heat exchangers and power plant is crucial to study lifecycle behavior of each component thereafter a later coupling to study lifecycle and recovery of the overall geothermal system. Study is divided into geothermal water cycle, surface heat exchanger ...

Investigation of Hydraulic Fracture Re-Orientation Effects in Tight Gas Reservoirs

[1]Clausthal University of Technology, Clausthal-Zellerfeld, Germany

In tight gas formations where the low matrix permeability prevents successful and economic production rates, hydraulic fracturing is required to produce a well at economic rates. As production from the well and its initial fracture declines, re-fracturing treatments are required to accelerate recovery. The orientation of the following hydraulic fracture depends on the actual stress-state of the ...

Analysis of 1D, 2D, and 3D Marine CSEM in COMSOL Multiphysics® Software - new

E. C. Luz[1]
[1]Universidade Federal do Pará, Belém, PA, Brazil

The Marine Controlled Source ElectroMagnetic (marine CSEM) is a geophysical method used by the oil industry to investigate resistive targets in the sediments under the ocean floor. In this work we simulate marine CSEM data including 1D, 2.5D and 3D modeling. The results obtained with COMSOL Multiphysics show themselves as a promising tool for the studies of electromagnetic methods in prospecting ...

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 ...

Use of COMSOL as a Tool in the Design of an Inclined Multiple Borehole Heat Exchanger

E. Johansson[1], J. Acuña[1], B. Palm[1]
[1]Royal Institute of Technology KTH, Stockholm, Sweden

A field of connected boreholes can be used both for cooling, heating and storage purposes. The boreholes transfer heat to or from the ground, which over time changes the temperature in the ground. It is important that the borehole field is properly sized and evaluated before the construction. This study presents results from borehole field evaluations of inclined boreholes used for cooling ...

A Numerical Simulation of Adsorption Using Non-Standard Isotherm Equations in COMSOL

A. Ortiz-Tapia, D. Lopez-Falcon, M. Diaz-Viera, S. Lopez-Ramirez, and J. Mendoza-dela-Cruz
Instituto Mexicano del Petroleo, D. F., Mexico

Numerical simulations of the equation of transport were performed using an adsorption isotherm equation, and a simple cubic polynomial. The 1D COMSOL implementation included solutes being injected from one face of a homogeneous, isotropic core (small sample of reservoir rock); where the concentration of injected surfactant was kept constant during the simulation. The spatial distribution of ...

3D Modeling of Fracture Flow in Core Samples Using ?-CT Data

Knowledge on flow behavior in fractured reservoir rocks is of great interest in petroleum engineering as well as for geothermal assets. Due to the big difference of magnitude (fracture aperture: ~?m, lateral extension of reservoirs ~km), modeling of discrete fracture flow is not practicable on the reservoir scale, so a Darcy (or Brinkman) approximation has to be found. The key task is to find ...

Direct Pore-scale Modeling of Two-phase Flow Through Natural Media

Open and Experimental Centre for Heavy Oil (CHLOE)
University of Pau
Pau, France

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 ...

Finite Element Solution of Nonlinear Transient Rock Damage with Application in Geomechanics of Oil and Gas Reservoirs

S. Enayatpour[1], T. Patzek[1]
[1]The University of Texas at Austin, Austin, TX, USA

The increasing energy demand calls for advances in technology which translate into more accurate and complex simulations of physical problems. Understanding the rock damage is essential to understanding the geomechanics of hydrocarbon reservoirs. The fragile microstructure of some rocks makes it difficult to predict the propagation of fracture in these rocks, therefore a mathematical model is ...
