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 ...
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 ...
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 ...
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 ...
Numerical Methods for Conservation Laws with a Discontinuous Flux Function
(The University of Bergen, 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 ...
