Karakterisering av strømning gjennom en forkastning med fault facies- og standardmodell ved bruk av reservoarsimulator
(Master thesis, 2011-11-21)Forkastninger har en betydelig innvirkning på strømninger i et reservoar. Hittil har forkastninger blitt modellert som en flate eller et plan i vanlige reservoarsimulatorer, men studier har vist at forkastninger ofte må ... -
Multiscale mass conservative domain decomposition preconditioners for elliptic problems on irregular grids
(Peer reviewed; Journal article, 2011-06)Multiscale methods can in many cases be viewed as special types of domain decomposition preconditioners. The localisation approximations introduced within the multiscale framework are dependent upon both the heterogeneity ... -
Numerical Methods for Conservation Laws with a Discontinuous Flux Function
(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 ... -
Sampling error distribution for the ensemble Kalman filter update step
(Peer reviewed; Journal article, 2012)In recent years, data assimilation techniques have been applied to an increasingly wider specter of problems. Monte Carlo variants of the Kalman filter, in particular, the ensemble Kalman filter (EnKF), have gained significant ...
