Spontaneous imbibition in igneous rocks: effect of KCl concentration, confining pressure, and imbibition direction

open access: yesJournal of Petroleum Exploration and Production Technology, 2020
Understanding spontaneous imbibition helps to determine the fracturing fluid volume and optimize the flowback design. At present, many studies have mainly focused on shale, but few on igneous rocks.

Spontaneous Imbibition Experiment in Newspaper Sheets

open access: yesPhysical Review Letters, 2010
We study the behavior of an ink-paper interface in a spontaneous imbibition experiment as a function of time and paper orientation. To characterize the interface roughness the growth beta and Hurst H exponents (calculated using the root mean square interface width W) and the H{q} scaling exponent (calculated using the qth order height-height ...

Investigation on the Application of NMR to Spontaneous Imbibition Recovery of Tight Sandstones: An Experimental Study

open access: yesEnergies, 2018
In this paper, the nuclear magnetic resonance (NMR) technique is applied to exploring the spontaneous imbibition mechanism in tight sandstones under all face open (AFO) boundary conditions, which will benefit a better understanding of spontaneous ...

Effect of viscosity on oil recovery by spontaneous imbibition from partially water-covered matrix blocks

open access: yesEnergy Exploration & Exploitation, 2021
Spontaneous imbibition is an important mechanism of oil recovery from fractured reservoirs and unconventional reservoirs. Oil is produced by combining co- and counter-current imbibition when the matrix blocks was partially covered by water. In this paper,

Characteristic Forced and Spontaneous Imbibition Behavior in Strongly Water-Wet Sandstones Based on Experiments and Simulation

open access: yesEnergies, 2022
 Forced and spontaneous imbibition of water is performed to displace oil from strongly water-wet Gray Berea (~130 mD) and Bentheimer (~1900 mD) sandstone core plugs.

Spontaneous Chemiluminescence of Soybean Embryonic Axes during Imbibition [PDF]

open access: yesPlant Physiology, 1984
Isolated soybean (Glycine max L. var Hood) embryonic axes have a spontaneous chemiluminescence (about 150 counts per minute per embryo) that increases showing two phases, upon water imbibition. The first photoemission burst was measured between 0 and 7 hours of imbibition with a maximum of about 350 counts per minute per embryo after 2 hours.

Spontaneous imbibition characteristics of diatomite

open access: yesJournal of Petroleum Science and Engineering, 2000
Abstract A systematic investigation of fluid flow characteristics within diatomite (a high porosity, low permeability, siliceous rock) is reported. Using an X-ray computerized tomography (CT) scanner, and a novel, CT-compatible imbibition cell, we study spontaneous cocurrent water imbibition into diatomite samples. Air–water and oil–water systems are

Fractal model equation for spontaneous imbibition

open access: yesRevista Mexicana de Física, 2020
A new analytic model of fractal imbibition in porous media is derived. The topological Hausdorff dimension is used as a fractal parameter inthe proposed model. The fractal formulation is based on the model introduced by Li and Zhao to predict the production rate by spontaneousimbibition.

Pore-scale Processes in Amott Spontaneous Imbibition Tests [PDF]

open access: yesProceedings, 2017
We observed the redistribution of the oil phase in the pore space of the rock in real-time in water-wet and mixed-wet (by ageing in crude oil) carbonate samples. During the imbibition of the water phase both, pore filling events with connection to the surrounding brine as well as snap-off events connected through water films only were detected.

Water imbibition and water sealing in water-driven gas reservoirs development

open access: yesEnergy Exploration & Exploitation, 2023
To improve the poor understanding of the mechanism of spontaneous water imbibition in water invasion in gas reservoirs and overcome the difficulty in quantifying imbibed water and its impact on reservoir development, a study is carried out based on ...
