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.

Spontaneous Water Imbibition into Diatomite

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.

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 in parallel layers of packed beads

The European Physical Journal E, 2017
The imbibition of a wetting fluid in a homogeneous porous medium follows the diffusion-like behavior described by Washburn. The impregnation of a two-layered porous medium by a wetting fluid due to capillary action has been previously described to have two fronts, one saturating the medium and the other, leading front, which propagates in finer pores ...

Wettability Evaluation by Spontaneous Imbibition Measurement

Jornual of AL-Farabi for Engineering Sciences, 2022
The propensity of one fluid in a fluid pair to coat the surface voluntarily is known as wettability. Fluid distribution and flow behavior in porous rocks mainly controlled by wettability. Oil recovery by water flooding depend mainly on the wettability of the reservoir rock. Many methods used for wettability measurement.

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 ...

Spontaneous Imbibition in Niger Delta Cores

SPE Nigeria Annual International Conference and Exhibition, 2016
Abstract Spontaneous imbibition is a process where the non-wetting fluid is displaced by the wetting fluid in a porous medium by means of capillary forces. Spontaneous imbibition plays a key role in oil recovery. This paper presents experimental data for countercurrent spontaneous imbibition into cores with different ...

Nonequilibrium Effects During Spontaneous Imbibition

Transport in Porous Media, 2006
Accurate models of multiphase flow in porous media and predictions of oil recovery require a thorough understanding of the physics of fluid flow. Current simulators assume, generally, that local capillary equilibrium is reached instantaneously during any flow mode.

Spontaneous Imbibition and Imbibition Oil Recovery in Tight Rocks

2017
Advances in the development of unconventional resources have led to a surge in North American oil production. For example, tight oil production has pushed the U.S. crude supply to over 9% of world total production. Therefore, petrophysical characterization of such low-permeability rocks, has become increasingly important for petroleum engineers ...

Analytical solution to spontaneous imbibition under vertical temperature gradient based on the theory of spontaneous imbibition dynamics

Journal of Petroleum Science and Engineering, 2019
Abstract In this work, we have theoretically studied the imbibition process related to a block in a fractured carbonate reservoir under an assumed constant, vertical temperature gradient, GT. An analytical solution to an ordinary differential equation we developed has been obtained using a computer program, and the original Washburn law normally ...
