Prediction of Three-Phase Capillary Pressure using a Network Model Anchored to Two-Phase Data
(Journal article, 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 ... -
Modelling of immiscible WAG with emphasis on the effect of capillary pressure
(Doctoral thesis, 2008-04-30) -
Effect of Implementing Three-Phase Flow Characteristics and Capillary Pressure in Simulation of Immiscible WAG
(Journal article, 2008-04-30)The effect of including a three-phase representation of the flow parameters and capillary pressure has been investigated using a black oil simulator. The simulation approaches include the complexity of three-phase flow, ... -
Influence of Capillary Pressure on Estimation of Relative Permeability for Immiscible WAG Processes
(Journal article, 2008-04-30)Capillary pressure is one of the important parameters when describing flow in porous media. This parameter is nevertheless in some cases neglected, especially if no reliable measured data is available. The purpose of this ... -
Features concerning capillary pressure and the effect on two-phase and three-phase flow
(Chapter, 2008-04-30)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 ... -
Fluid Flow Properties of WAG Injection Processes
(Chapter, 2008-04-30)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 ... -
Kinetic description of particle emission from expanding source
(Peer reviewed; Journal article, 2008-05-22)The freeze out of the expanding systems, created in relativistic heavy ion collisions, is discussed. We combine kinetic freeze out equations with Bjorken type system expansion into a unified model. The important feature ... -
Dispersion and two-phase flow in material from different carbonate pore classes
(Master thesis, 2008-06-02)Carbonate reservoirs are currently estimated to contain more than 50 % of the world's oil reserves. The economical value of improving knowledge on fluid flow in these reservoirs is therefore vast. Carbonate reservoirs are ... -
Impacts on oil recovery from capillary pressure and capillary heterogeneities
(Doctoral thesis, 2008-06-02)This thesis summarises the findings made in NFR-funded project “Capillary Pressure and Capillary Heterogeneities”. The focus has been to determine the impact on oil recovery from wettability and fractures in carbonate ... -
Simulation of viscous instabilities in miscible and immiscible displacement
(Master thesis, 2008-06-09)This study includes modeling of viscous instabilities at both miscible and immiscible displacement. Oil recovery of heavy oil leads to unstable displacement for adverse mobility ratio for both miscible and immiscible ... -
Acoustic Methods for Obtaining the Pressure Reflection Coefficient from a Buffer Rod Based Measurement Cell
(Peer reviewed; Journal article, 2008-08-08)The known acoustic methods for obtaining the pressure reflection coefficient from a buffer rod based measurement cell are presented, along with 2 new generic approaches for measuring the pressure reflection coefficient ... -
A Novel Approach to Acoustic Liquid Density Measurements Using a Buffer Rod Based Measuring Cell
(Peer reviewed; Journal article, 2008-08-08)A new method for measuring the pressure reflection coefficient in a buffer rod configuration is presented, together with experimental results for acoustic measurements of the liquid density, based on the measurement of the ... -

A study of capillary pressure and capillary continuity in fractured rocks
(Doctoral thesis, 2008-09-05)The production of oil is challenging in fractured reservoirs due to the large transmissibility contrast between matrix and fracture, and primary recovery is often low. The recovery efficiency depends on the relationship ... -
The Hall current system revealed as a statistical significant pattern during fast flows
(Peer reviewed; Journal article, 2008-11-05)We have examined the dawn-dusk component of the magnetic field, BY , in the night side current sheet during fast flows in the neutral sheet. 237 h of Cluster data from the plasma sheet between 2 August 2002 and 2 October ... -

(Doctoral thesis, 2008-11-14) -
Poisson’s spot with molecules
(Peer reviewed; Journal article, 2009)In the Poisson-spot experiment, waves emanating from a source are blocked by a circular obstacle. Due to their positive on-axis interference an image of the source the Poisson spot is observed within the geometrical shadow ... -
Reactive Transport of CO2 in Saline Aquifers with implicit geomechanical analysis
(Peer reviewed; Journal article, 2009)Geological storage of CO2 in saline aquifers is a promising way to reduce the concentration of the greenhouse gas in the atmosphere. Injection of CO2 will, however, lead to dissolution of minerals in regions of lowered pH ... -
Quarkyonic matter from hydro and rapid freeze out
(Peer reviewed; Journal article, 2009)Quarkyonic matter is a predicted phase between deconfined ideal QGP and Hadronic matter where the dominant degrees of freedom are quarks. Collective flow measurements indicate that the flow developed in QGP, as flow ... -
