Estimation of Imbibition Capillary Pressure Curves from Spontaneous Imbibition Data
Energy & Fuels, 2009A 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. (

On Barenblatt's Model of Spontaneous Countercurrent Imbibition
Transport in Porous Media, 2004Water imbibition is a critical mechanism of secondary oil recovery from fractured reservoirs. Spontaneous imbibition also plays a significant role in storage of liquid waste by controlling the extent of rock invasion. In the present paper, we extend a model of countercurrent imbibition based on Barenblatt's theory of non-equilibrium two-phase flow by ...

Spontaneous Imbibition with Matched Liquid Viscosities
Proceedings of SPE Annual Technical Conference and Exhibition, 2005Abstract 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 ...

Effects of Capillary Heterogeneities on Spontaneous Imbibition
Proceedings of SPE Annual Technical Conference and Exhibition, 1995Abstract 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.

A General Scaling Method for Spontaneous Imbibition
SPE Annual Technical Conference and Exhibition, 2002AbstractScaling 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, 1974Abstract 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 ...

Abstract Countercurrent spontaneous imbibition is one of the basic processes in two-phase fluid flow in fractured porous media. Many researchers have studied modeling of this phenomenon and analytical and numerical solutions have been presented. Specifying the imbibition face (open face) wetting phase saturation, which acts as a boundary condition, has

Theoretical Investigation of the Transition From Spontaneous to Forced Imbibition
SPE Journal, 2018Summary Spontaneous and forced imbibition are recognized as important recovery mechanisms in naturally fractured reservoirs because the capillary force controls the movement of the fluid between the matrix and the fracture. For unconventional reservoirs, imbibition is also important because the capillary pressure is more dominant in ...

Characterization of Spontaneous Water Imbibition into Gas-Saturated Rocks
Proceedings of SPE/AAPG Western Regional Meeting, 2000Summary 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
