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 ...
Physico-Chemistry Characterization of Sulfonated Polyacrylamide Polymers for Use in Polymer Flooding
(The University of Bergen, 2010-06-01)
Hydrolyzed polyacrylamide polymer (HPAM) as a feasible and effective viscosifier has been fully studied and used for polymer flooding processes in several oil field, e.g. Daqing oil field. It has been shown that Hydrolyzed ...
Robust Control Volume Methods for Reservoir Simulation on Challenging Grids
(The University of Bergen, 2010-02-19)
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 ...
Crude oil components with affinity for gas hydrates in petroleum production
(The University of Bergen, 2007-06-28)
Some crude oils are believed to contain natural inhibiting components that can prevent hydrate plugging of oil pipelines in petroleum production. A method for classification of the oils that form hydrate plugs, as opposed ...
Robust Multiscale Control-volume Methods for Reservoir Simulation
(The University of Bergen, 2012-04-30)
An improved workflow for image- and laser-based virtual geological outcrop modelling
(The University of Bergen, 2013-03-15)
Photorealistic 3D models, representing an object’s surface geometry textured with conventional photography, are used for visualization, interpretation and spatial measurement in many disparate fields, such as cultural ...
Waterflood Efficiency and Single-Phase Flow Properties of Carbonate Porous Media
(The University of Bergen, 2009-12-17)
