Electrical conductivity of fractured media: A computational study of the self-consistent method 

Sævik, Pål Næverlid; Berre, Inga; Jakobsen, Morten; Lien, Martha (Society of Exploration Geophysicists, 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 ...

A unified multilevel framework of upscaling and domain decomposition 

Sandvin, Andreas; Nordbotten, Jan Martin; Aavatsmark, Ivar (International Center for Numerical Methods in Engineering (CIMNE), 2010)
We consider multiscale preconditioners for a class of mass-conservative domain-decomposition (MCDD) methods. For the application of reservoir simulation, we need to solve large linear systems, arising from finite-volume ...

Co2 trapping in sloping aquafiers: High resolution numerical simulations 

Elenius, Maria; Tchelep, Hamdi A.; Johannsen, Klaus (CIMNE, 2010)

An Approach for Investigation of Geochemical Rock-Fluid Interactions 

Bringedal, Carina; Berre, Inga; Radu, Florin A. (Stanford University, 2014)
Geochemistry has a substantial impact in exploiting of geothermal systems. When water is injected in a geothermal reservoir, the injected water and in-situ brine have different temperatures and chemical compositions and ...

Multiscale Simulation of Non-Darcy Flows 

Alyaev, Sergey; Keilegarden, Eirik; Nordbotten, Jan Martin (2012-06)
In this work we present control volume multiscale methods which address problems on the interaction between pore scale and Darcy scale. For the case when linear equations govern the ow on the pore scale our solution converges ...

Reexamining CO2 Storage Capacity and Utilization of the Utsira Formation 

Andersen, Odd; Nilsen, Halvor Møll; Lie, Knut-Andreas (EAGE, 2014)
In this work we provide estimates of CO2 storage capacity of the Utsira Formation using the recently provided datasets from the Norwegian Petroleum Directorate, taking CO2 density variation into account. We also investigate ...

On the relationship between multiple porosity models and continuous time random walk 

Nordbotten, Jan Martin; Vasilyev, Leonid (CIMNE, 2010)
We derive a multiple porosity model based on the continuous time random walk model (CTRW). In particular, we show how the parameters of the multiple porosity models relate to the transition probability function which is ...

Modelling of the Shear Dilation Based Hydraulic Stimulation in Enhanced Geothermal Systems Considering Fractures in Different Scales 

Ucar, Eren; Berre, Inga; Keilegavlen, Eirik (EGEC, 2016-09)
A numerical approach for modelling of shear dilation of existing fractures in hydraulic stimulation of geothermal reservoirs at low elevated pressures is presented. The fractured rock in the reservoir is modelled as ...

On the shoaling of solitary waves in the KdV equation 

Khorsand, Zahra; Kalisch, Henrik (American Society of Civil Engineers, 2014)
The waveheight change in surface waves with a sufficiently slow variation in depth is examined. Using a new formulation of the energy flux associated to waves modeled by the Korteweg-de Vries equation, a system of three ...
