A 3D computational study of effective medium methods applied to fractured media
Sævik, Pål Næverlid; Berre, Inga; Jakobsen, Morten; Lien, Martha (Peer reviewed; Journal article, 2013-10)This work evaluates and improves upon existing effective medium methods for permeability upscaling in fractured media. Specifically, we are concerned with the asymmetric self-consistent, symmetric self-consistent, and ... -
Electrical conductivity of fractured media: A computational study of the self-consistent method
Sævik, Pål Næverlid; Berre, Inga; Jakobsen, Morten; Lien, Martha (Conference object; Peer reviewed, 2012)Effective medium theory can be used to link conductivity estimation methods with prior knowledge about the distribution of fractures in the investigated geological structure. In the literature, little work has been presented ... -
Homotopy analysis of the Lippmann-Schwinger equation for seismic wavefield modeling in strongly scattering media
Jakobsen, Morten; Huang, Xingguo; Wu, Ru-Shan (Peer reviewed; Journal article, 2020)We present an application of the homotopy analysis method for solving the integral equations of the Lippmann-Schwinger type, which occurs frequently in acoustic and seismic scattering theory. In this method, a series ... -
On the applicability of a renormalized Born series for seismic wave modelling in strongly scattering media
Huang, Xingguo; Jakobsen, Morten; Wu, Ru-Shan (Peer reviewed; Journal article, 2020)Scattering theory is the basis for various seismic modeling and inversion methods. Conventionally, the Born series suffers from an assumption of a weak scattering and may face a convergence problem. We present an application ... -
On the relative importance of global and squirt flow in cracked porous media
Ali, Aamir; Jakobsen, Morten (2011)A unified theory of global and squirt flow in cracked porous media was developed several years ago on the basis of a combination of the dynamic T-matrix approach to rock physics. The theory has been successfully used to ... -
Seismic characterization of reservoirs with multiple fracture sets using velocity and attenuation anisotropy data
Ali, Aamir; Jakobsen, Morten (2011)Knowledge about the spatial distribution of the fracture density and the azimuthal fracture orientation can greatly help in optimizing production from fractured reservoirs. Frequency-dependent seismic velocity and attenuation ...
