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

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 ... Mehr lesen

Numerical Modeling of the Near-Subsurface Temperature Distributions in the Presence of Time Varying Air Temperature in the Boundary Condition and Space Varying Temperature for the Initial Condition

M. Ravi[1], D. V. Ramana[1], R. N. Singh[1]
[1]CSIR - National Geophysical Research Institute, Hyderabad, Telangana, India

The subsurface thermal structure in presence of groundwater recharge/discharge has been obtained by applying the Robin type boundary condition at the earth’s surface. The Robin type boundary condition involves the effect air temperatures at the surface which are taken as exponentially ... Mehr lesen

2-Dimensional Incompressible and Compressible Mantle Convection

Changyeol Lee[1]
[1]Faculty of Earth and Environmental Sciences, Chonnam National University, Gwangju, Republic of Korea

COMSOL Multiphysics® software has been used in computational geodynamics for years. Because very high pressure in the mantle even significantly compressed the mantle up to ~40%, it is crucial to consider the mantle compressibility in computational geodynamics. COMSOL Multiphysics allows ... Mehr lesen

Electromagnetic Well Logs Simulated with the COMSOL® RF Module on a Cluster

D. Swaminathan[1], G. Minerbo[1], K. Pathak[1]
[1]Drilling and Production Group, Schlumberger, Houston, TX, USA

Introduction Computer simulations are widely used for the interpretation and inversion of electromagnetic measurements in well logging. Until recently, simulated logs have been computed with approximate 1D or 2D models. By using the COMSOL® RF Module installed on a cluster, we show that ... Mehr lesen

Estimation of Hydraulic Conductivity for a Heterogeneous Unsaturated Soil Using Electrical Resistivity and Level-Set Methods

T. K. Chou[1], M. Chouteau[1], J. S. Dubé[2]
[1]École Polytechnique de Montréal, Montréal, QC, Canada
[2]École de Technologie Supérieure, Montréal, QC, Canada

The estimation of the soil saturated hydraulic conductivity (Ks) is crucial in understanding water flow and transport of contaminants. There are many hydrological techniques available in determining this parameter (constant head method, in-situ soil analysis, etc...). While these ... Mehr lesen

Delamination of Sub-Crustal Lithosphere

P. Vincent[1], E. Humphreys[2]
[1]College of Earth, Ocean, & Atmospheric Sciences, Oregon State University, Corvallis, OR, USA
[2]Department of Geological Sciences, University of Oregon, Eugene, OR, USA

Introduction: Lithospheric delamination beneath the western U.S. is believed to be the driving mechanism responsible for the evolution of magmatic and topographic features observed at the surface in the western U.S.. This process requires hot asthenosphere to be in contact with the ... Mehr lesen

Geomagnetic Modeling with COMSOL Multiphysics® Software

G. Ha[1], S. S. Kim[1], J. H. Kim[1]
[1]Chungnam National University, Daejeon, Korea

Here we aim to advance geomagnetic modeling approaches using COMSOL Multiphysics® software and improve the degree of detail that can be obtained from the measured magnetic field. First, we carried out benchmark tests by comparing the computed results using the widely used analytic ... Mehr lesen

Verification of the Numerical Simulation of Permafrost Using COMSOL Multiphysics® Software

E. Dagher[1], G. Su[1], T. S. Nguyen[1]
[1]Canadian Nuclear Safety Commission, Ottawa, ON, Canada

COMSOL® software was used to simulate the conductive heat transfer with phase change in the geological formations encompassed in permafrost surrounding a shallow thaw lake. The purpose of the simulation was to verify the adequacy of COMSOL to model such phenomena by comparing the COMSOL ... Mehr lesen

S. Lazzari[1], A. Priarone[2],
[1]DIN, University of Bologna, Bologna, Italy
[2]DIME-TEC, University of Genova, Genova, Italy

The transient behavior of the thermal resistance of single and double U-tube borehole heat exchangers (BHEs) is investigated numerically by means of COMSOL Multiphysics® software with reference to the 2D cross section of usually employed BHEs. The study is performed in a dimensionless ... Mehr lesen
