The prediction of spontaneous oil-water imbibition in composite capillary
Petroleum, 2022 In view of the classical Lucas-Washburn equation, which can only describe the spontaneous imbibition of single wetted capillary, a tilted composite capillary model with circular cross section, composed of different wettability capillary wall was ...

Measurement and Modeling of Spontaneous Capillary Imbibition in Coal [PDF]
ACS Omega, 2020 Coal is a typical dual-porosity medium. The implementation process of water invasion technology in coal is actually a process of spontaneous imbibition of external water. To obtain a model of spontaneous capillary imbibition in coal, the spontaneous imbibition of water in coal samples with different production loads is conducted experimentally.

Spontaneous Imbibition in Small Cores [PDF]
Asia Pacific Oil and Gas Conference and Exhibition, 2007 Abstract This paper presents experimental data for co-current spontaneous imbibition into cores having bulk volumes from 0.1 to 12 cm3. Simple experiments of brine imbibing into air-filled cores were carried out. Homogeneous sandstone cores (Berea and Bentheim) and a carbonate core (Mt. Gambier) were used in the experiments.

Abnormal Phenomena and Mathematical Model of Fluid Imbibition in a Capillary Tube
Energies, 2022 At present, the imbibition behavior in tight rocks has been attracted increasing attention since spontaneous imbibition plays an important role in unconventional oil and gas development, such as increasing swept area and enhancing recovery rate. However,

Theoretical Investigation of the Transition from Spontaneous to Forced Imbibition
SPE Journal, 2018 Spontaneous and forced imbibition are recognized as important recovery mechanisms in naturally fractured reservoirs as the capillary force controls the movement of the fluid between the matrix and the fracture.
