Identification of subsurface structures using electromagnetic data and shape priors

Tveit, Svenn; Bakr, Shaaban A.; Lien, Martha; Mannseth, Trond (Journal article, 2015-03)

We consider the inverse problem of identifying large-scale subsurface structures using the controlled source electromagnetic method. To identify structures in the subsurface where the contrast in electric conductivity can ...
Inversion of CSEM Data for Subsurface Structure Identification and Numerical Assessment of the Upstream Mobility Scheme

Tveit, Svenn (Doctoral thesis, 2015-03-27)

Part I In this part of the thesis, two different methodologies for solving the inverse problem of mapping the subsurface electric conductivity distribution using controlled source electromagnetic (CSEM) data are presented. ...
Numerical Methods for Conservation Laws with a Discontinuous Flux Function

Tveit, Svenn (Master thesis, 2011-06-01)

When simulating two-phase flow in a porous medium, numerical methods are used to solve the equations of flow, called conservation laws. In the industry, this is done by a reservoir simulator, and the most widely used method ...
