Fluid Flow Properties of WAG Injection Processes
Immiscible water-alternating-gas (IWAG) experiments performed on equilibrated fluids are summarised together with the corresponding two-phase gas-oil and water-oil displacements. Experimental studies at reservoir condition ...
Features concerning capillary pressure and the effect on two-phase and three-phase flow
The effect of capillary pressure related to immiscible WAG (Water Alternate Gas) is studied by use of a numerical simulator. The capillary pressure is found to have a significant effect on the pressure gradient and the ...
Primary Drainage Capillary Pressure Curves in Heterogeneous Carbonates with Ultracentrifuge and NMR
(The University of Bergen, 2010-06-01)
Capillary pressure is one of the most fundamental rock-fluid characteristics in multi-phase flow, critically influencing both the initial reservoir fluid distribution and the dynamic processes of oil recovery. Thus, it is ...
Modelling of immiscible WAG with emphasis on the effect of capillary pressure
(The University of Bergen, 2008-04-30)
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 ...
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 ...
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 ...
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 ...
NMR measurements of wettability alternation in Berea Sandstone
(The University of Bergen, 2011-11-28)
When a new oil reservoir is discovered and a production strategy is chosen the knowledge about wettability characteristics for the field is of outermost importance. Wettability is a key factor for fluid distribution ...
