Spontaneous imbibition of water into a matrix block is a very complex process and depends on many factors such as permeability, wettability, shape, and size of the matrix, boundary conditions, and interfacial tension and viscosities of the fluid system.
Scaling of spontaneous imbibition has long been used as a predictive tool for estimating the field performance of water-wet, fractured reservoirs subjected to water flood/drive.
The aim of this paper is to provide simple and well-defined experimental data for spontaneous imbibition in order to demonstrate that reliable experimental data can be produced on small core plugs which are of comparable size to rock fragments used in micro-CT imaging.
w] is the water viscosity and t is the imbibition time.
Scaling of spontaneous imbibition is another approach to predict field-scale performance.
Based on the scaling law reported by Rapoport and Leas [16], Mattax and Kytes [6] presented an equation to scale the behavior of hydrocarbon recovery from strongly water-wet fractured oil reservoirs by means of spontaneous imbibition,
Spontaneous imbibition of water into gas-saturated porous rocks can be considered to be a piston-like displacement with the imbibed mass given by the Handy [13] equation,
The networks extracted from the images are used in models to predict multiphase flow properties such as relative permeability, capillary pressure and spontaneous imbibition process.
9 scales the spontaneous imbibition of water into different porous media (Berea, chalk, and Graywacke cores) with different initial water saturations.
The shortcoming of the scaling law, as reported by the authors, is the difficulty in correlating the entire imbibition process for different rock types.
S] could not correlate data for one-end-open system counter-current imbibition with that for all-face-open systems.
Ai] is the distance that the imbibition front moves from inlet to the outer boundary.
