Facies composition and scaling of extensional faults in sedimentary rocks and its applications to modelling of fault zones
(The University of Bergen, 2010-01-08)
An improved workflow for image- and laser-based virtual geological outcrop modelling
(The University of Bergen, 2013-03-15)
<p>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 ...
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 ...
3D stochastic modelling of fault zones in siliciclastic reservoirs. Implications for reservoir description and fluid flow modelling
(The University of Bergen, 2014-12-16)
<p>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 ...
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 ...
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 ...
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 ...
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 ...
Modelling of immiscible WAG with emphasis on the effect of capillary pressure
(The University of Bergen, 2008-04-30)
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 ...
