[1] We report on laboratory experiments designed to investigate the influence of pore pressure oscillations on the effective permeability of fractured rock. Berea sandstone samples were fractured in situ under triaxial stresses of tens of megapascals, and deionized water was forced through the incipient fracture under conditions of steady and oscillating pore pressure. We find that short‐term p...

12 We report on laboratory experiments designed to investigate the effect of 13 dynamic stressing on permeability of fractured rock. Berea sandstone samples 14 were fractured in-situ under triaxial stresses of 10's of MPa, and deionized 15 water was forced through the incipient fracture under conditions of steady and 16 oscillating pore pressure. We find that dynamic stresses produced by pore 1...

An experimental and theoretical investigation of the influence of high-frequency acoustic waves on the flow of a liquid through a porous material has been made. Particular attention was paid to the phenomenon of acoustic streaming of the liquid in the porous material due to the damping of the acoustic waves. The experiments were performed on Berea sandstone cores. Two acoustic horns were used w...

Abstract The use of nanoparticles (NPs) can considerably benefit enhanced oil recovery (EOR) by changing the wettability rock, improving mobility drop, and decreasing interfacial tension (IFT) between water. Prior to application in fields, it is essential conduct measurements at laboratory scale. However, estimation reservoir difficult most experiments. Practicably, ZnO NPs were used modify roc...

In this paper, we present a reliable micro-to-macroscale framework to model multiphase fluid flow through fractured porous media. This is based on utilizing the capabilities of lattice Boltzmann method (LBM) within phase-field modeling (PFM) fractures in this, propose new physically motivated phase-field-dependent relationships for residual saturation, intrinsic as well relative permeabilities....

Understanding the adsorption behavior of nitrogen heterocyclic compounds (NHCs) on soil minerals underlies more effective design wastewater treatment and soil/groundwater remediation. We investigated quinoline, a representative NHC, quartz sand (using Berea sandstone as model), at 3 < pH 9, in low (0.05 M) high (0.7 ionic strength solutions where NaCl was background electrolyte. Minor clay (kao...
