Spontaneous Imbibition with Matched Liquid Viscosities

Proceedings of SPE Annual Technical Conference and Exhibition, 2005
Abstract Laboratory results of oil recovery through spontaneous imbibition are commonly scaled-up to forecast oil recovery from fractured reservoirs. This study addresses oil recovery from cylindrical sandstone cores by spontaneous imbibition at very strongly water-wet conditions for viscosity ratios of unity (a special case of the ...

Estimation of Imbibition Capillary Pressure Curves from Spontaneous Imbibition Data

Energy & Fuels, 2009
A closed-form solution for calculating imbibition capillary pressure from experimental data has been derived on the basis of the assumption of a constant capillary diffusion coefficient combined with Corey functions for the relative permeability curves. The solution is almost similar to the capillary pressure correlation reported by Skjaeveland et al. (

Effects of Capillary Heterogeneities on Spontaneous Imbibition

Proceedings of SPE Annual Technical Conference and Exhibition, 1995
Abstract This paper presents numerical studies of spontaneous imbibition phenomenon in a heterogeneous matrix block of porous medium in one and two dimensional systems. Heterogeneous distributions of permeability as well as wettability that could affect spontaneous imbibition are considered.

New normalization index for spontaneous imbibition

Journal of Petroleum Science and Engineering, 2012
Abstract Spontaneous imbibition is of special importance in oil recovery from fractured reservoirs. Laboratory measurements of volume of liquid imbibed versus time are often used in the prediction of oil recovery. Laboratory results of oil recovery through spontaneous imbibition are commonly scaled-up to forecast oil recovery at the reservoir scale ...

A General Scaling Method for Spontaneous Imbibition

SPE Annual Technical Conference and Exhibition, 2002
AbstractScaling the experimental data of spontaneous imbibition without serious limitations has been difficult. To this end, a general approach was developed to scale the experimental data of spontaneous imbibition for most systems (gas-liquid-rock and oil-water-rock systems) in both cocurrent and countercurrent cases.

Spontaneous Imbibition of Fluids in Porous Vycor

Society of Petroleum Engineers Journal, 1974
Abstract The spontaneous imbibition of alkanes and alcohols in pores of 35 radius has been studied. At a rather critical molecular size The pore volume becomes insensitive to the size of imbibing molecule. Darcy's law for transient imbibition kinetics is obeyed, fluid viscosity and surface tension are valid flow ...

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
