Derivations of the Young-Laplace equation
Siqveland, Leiv Magne; Skjæveland, Svein Magne (Journal article, 2021-04)The classical Young-Laplace equation relates capillary pressure to surface tension and the principal radii of curvature of the interface between two immiscible fluids. In this paper the required properties of space curves ... -
Development of new oil/water partitioning tracers for the determination of residual oil saturation in the inter-well region of water-flooded reservoirs
Helder Lopes da Silva, Mario (PhD thesis UiS;, Doctoral thesis, 2021-03)Most of the hydrocarbon-rich large unexplored basins are located in remote and/or highly environmentally sensitive regions. As more and more oilfields reach maturity at the end of the secondary stage of recovery, while on ... -
Footprints of spontaneous fluid redistribution on capillary pressure in porous rock
Helland, Johan Olav; Friis, Helmer Andre`; Jettestuen, Espen; Skjæveland, Svein Magne (Journal article; Peer reviewed, 2017-05)Pore-scale imaging of two-phase flow in porous media shows that pore filling occurs as cooperative events with accompanying spontaneous fluid redistribution in other parts of the pore space. We present a level set method ... -
Interpretation of 1-D Counter-Current Spontaneous Imbibition Processes Using Microscopic Diffusion Theory and a Modified Buckley – Leverett Approach
Standnes, Dag Chun; Andersen, Pål Østebø; Papatzacos, Paul Georg; Skjæveland, Svein Magne (Peer reviewed; Journal article, 2020-04)This paper presents a new convenient and easy-to-use method to analyze and calculate measurable quantities in 1-D counter-current (COUC) spontaneous imbibition (SI) processes. Cumulative water imbibed vs time can be ...
