Spontaneous Water Imbibition into Diatomite

Proceedings of SPE Western Regional Meeting, 1998
Abstract A systematic experimental investigation of capillary pressure characteristics and fluid flow in diatomite has begun. Using an X-ray CT scanner and a specially constructed imbibition cell, we study spontaneous water imbibition processes in diatomite and for reference Berea sandstone and chalk.

Effect of Initial Water Saturation on Spontaneous Water Imbibition

Proceedings of SPE Western Regional/AAPG Pacific Section Joint Meeting, 2002
Abstract The effect of initial water saturation on gas recovery by cocurrent spontaneous water imbibition and imbibition rate was investigated both theoretically and experimentally. Equations correlating initial water saturation, gas recovery, imbibition rate, rock/fluid properties, and imbibition time were derived and used to conduct ...

Initial water saturation and imbibition fluid affect spontaneous imbibition into Barnett shale samples

Journal of Natural Gas Science and Engineering, 2016
Abstract Spontaneous imbibition has been widely investigated due to its significant impact on gas/oil recovery from conventional sandstone and carbonate reservoirs. Unlike conventional reservoir rocks with relative high porosity and permeability, shale is characterized by its low porosity (

Capillary Pressure at the Imbibition Front During Water–Oil Counter-Current Spontaneous Imbibition

Transport in Porous Media, 2008
Counter-current spontaneous imbibition (COUCSI) in porous media is driven by capillary forces. Capillary action results in a high capillary imbibition pressure at the imbibition front and a low capillary drainage pressure at the outlet face. It is the difference between these two pressures that draws in the wetting phase and pushes out the non-wetting ...

Water imbibition by normal and hard soybeans

Journal of the American Oil Chemists' Society, 1981
AbstractBy observing the imbibition of dyed water, soybeans were classified into damaged (break in seed coat), normal and hard beans. Hard soybeans were unique in having a long, variable lag time before start‐ing imbibition, but once water uptake was started, the rate was similar to that of normal beans. Soaking hard beans in methanol or ethanol for 24

Characterization of Spontaneous Water Imbibition into Gas-Saturated Rocks

Proceedings of SPE/AAPG Western Regional Meeting, 2000
Summary A method has been developed to characterize the process of spontaneous water imbibition into gas-saturated rocks. Water relative permeability and capillary pressure can be calculated simultaneously from water imbibition data using this method. A linear relationship between imbibition rate and the reciprocal of the gas recovery by

Soybean Seed Imbibition: Water Absorption by Seed Parts

Crop Science, 1988
Seed imbibition is a critical stage in successful soybean [Glycine max (L.) Merr.] crop establishment. This study investigatesoybean seed imbibition with emphasis on absorption of water by the seed parts (seed coat, embryonic axis, cotyledons, and whole seed). Mter 72 h imbibition, the embryonic axis was the most hydrated portion of the seed possessing
