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 ... -
Practical approaches to study microbially induced calcite precipitation at the field scale
Marban, David Landa; Tveit, Svenn; Kumar, Kundan; Gasda, Sarah (Journal article; Peer reviewed, 2021)Microbially induced calcite precipitation (MICP) is a new and sustainable technology which utilizes biochemical processes to create barriers by calcium carbonate cementation; therefore, this technology has a potential to ...
