3D stochastic modelling of fault zones in siliciclastic reservoirs. Implications for reservoir description and fluid flow modelling
(The University of Bergen, 2014-12-16)
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 ...
Modelling of Three-Phase Flow Functions for Applications in Enhanced Oil Recovery
(The University of Bergen, 2009-05-22)
Waterflood Efficiency and Single-Phase Flow Properties of Carbonate Porous Media
(The University of Bergen, 2009-12-17)
Value of different data types for estimation of permeability
(The University of Bergen, 2011-06-01)
The interrelation between sensitivity, non-linearity and scale, associated with the inverse problem of identifying permeability from measurements of fluid flow, is considered. The gouverning equations for fluid flow in a ...
Effect of Implementing Three-Phase Flow Characteristics and Capillary Pressure in Simulation of Immiscible WAG
(The University of Bergen, 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, ...
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 ...
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)
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 ...
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 ...
