Robust Multiscale Control-volume Methods for Reservoir Simulation
(The University of Bergen, 2012-04-30)
Prediction of Three-Phase Capillary Pressure using a Network Model Anchored to Two-Phase Data
(The University of Bergen, 2008-04-30)
Three-phase capillary pressure is difficult to measure experimentally and therefore has to be estimated by other methods. In this work a network model was applied to generate a consistent set of two-phase and three-phase ...
3D stochastic modelling of fault zones in siliciclastic reservoirs. Implications for reservoir description and fluid flow modelling
(The University of Bergen, 2014-12-16)
Fault zones in siliciclastic rocks form distinct volumetric entities and typically exhibit great structural complexity. While it has been considered that the main impact of fault zones to fluid flow is to baffle or block ...
Characterization of Linked Polymer Solutions (LPS) – Influence of salinity and divalent ions
(The University of Bergen, 2011-05-31)
Water flooding with addition of polymers cross-linked by polyvalent ions (LPS) has proven to increase the oil recovery both in field applications and laboratory studies, but with constraints on the brine salinity. With of ...
Karakterisering av strømning gjennom en forkastning med fault facies- og standardmodell ved bruk av reservoarsimulator
(The University of Bergen, 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 ...
Seismic properties of carbonate rocks with emphasis on effects of the pore structure
(The University of Bergen, 2007-06-18)
Quality of the Analysis Step in EnKF
(The University of Bergen, 2011-06-15)
In many physical applications we want to characterize the parameters of a system based on indirect observations or measurements. In a reservoir simulator setting, the goal is to simulate the production of hydrocarbons ...
Continuous Updating of a Coupled Reservoir-Seismic Model Using an Ensemble Kalman Filter Technique
(The University of Bergen, 2007-03-29)
This work presents the development of a method based on the ensemble Kalman filter (EnKF) for continuous reservoir model updating with respect to the combination of production data, 3D seismic data and time-lapse seismic ...
4D Seismic History Matching Using the Ensemble Kalman Filter (EnKF): Possibilities and Challenges
(The University of Bergen, 2010-05-27)
This research endeavor presents a 4D seismic history matching work flow based on the ensemble Kalman filter (EnKF) methodology. The objective of this work is to investigate the sensitivity of different combinations ...
A 2-D Visualisation Study of the Mechanisms behind Increased Recovery due to Polymer Injection in Sandstone
(The University of Bergen, 2011-11-20)
The potential of synthetic polymer injection, such as hydrolysed polyacrylamide (HPAM), in reservoirs has been a field of study since the 1960's . The main intension of polymer injection is to improve the problems ...
