Fractal Prediction Model of Spontaneous Imbibition Rate

Transport in Porous Media, 2011
By utilizing fractal dimension as one of the parameters to characterize rocks, a mathematical model was derived to predict the production rate by spontaneous imbibition. This fractal production model predicts a power law relationship between spontaneous imbibition rate and time. Fractal dimension can be estimated from the fractal production model using

Scaling of spontaneous imbibition data with wettability included

Journal of Contaminant Hydrology, 2007
Wettability is a dominant parameter governing spontaneous imbibition. However less attention has been paid to the effect of wettability on the scaling of spontaneous imbibition data. Actually few models can include wettability in scaling of spontaneous imbibition data.

Pressures acting in counter-current spontaneous imbibition

Journal of Petroleum Science and Engineering, 2006
Abstract Four water/oil and four oil/air linear counter-current spontaneous imbibition experiments were performed on Berea sandstone cores with permeabilities ranging from 0.065 to 1.094 μm 2 . The cores were initially 100% saturated with non-wetting phase and all faces except one end were sealed.

An Experimental Investigation of Spontaneous Imbibition in Gas Shales

SPE Annual Technical Conference and Exhibition, 2011
Abstract Multi-stage horizontal wells play an important role in the development of domestic shale-gas resources. The completion strategy for shale-gas wells commonly includes hydraulic fracturing that utilizes large volumes of fresh (and recycled water) complimented by the addition of assorted chemicals.

Spontaneous imbibition processes in Hele‐Shaw cells

AIChE Journal, 2001
AbstractExperiments on spontaneous imbibition processes in Hele‐Shaw cells were carried out in squared cells (20 cm × 20 cm) with separations of 0.005, 0.015 and 0.075 cm using twice‐distilled water and Soltrol 170 as the displacing and displaced fluids, respectively.

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 ...

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.

Spontaneous imbibition in randomly arranged interacting capillaries

Chemical Engineering Science, 2018
Abstract Spontaneous imbibition in a porous medium is known to have two macroscopic fronts, the leading one in narrow pores and the lagging front in the wider pores. This behavior contradicts the behavior predicted by Washburn law due to interaction of the pores in the porous medium. In this work, we investigate the spontaneous imbibition behavior in
