Fines migration and pore clogging induced by single- and two-phase fluid flows in porous media: From the perspectives of particle detachment and particle-level forces

, 2020
Depressurization of hydrate-bearing sediments (HBS) is inevitably accompanied with sediment transport, not only structural host sediment itself but also fine particles, which can be a significant problem in producing gases from HBS, as demonstrated in ...

Compositional modeling of nanoparticle-reduced-fine-migration

Journal of Natural Gas Science and Engineering, 2016
Abstract During waterflooding, formation fines migration is a recognized reason for well injectivity and productivity reduction in sandstone reservoirs. Permeability decrease due to fines migration is one of the major issues in the application of low salinity enhanced oil recovery techniques.

Effect of fines migration and mineral reactions on CO2-water drainage relative permeability

, 2020
CO2-water drainage relative permeability is usually measured in laboratory using a three-stage unsteady-state flooding on cores. This three-stage flooding involves injecting water, then CO2-saturated water, and finally water-saturated supercritical CO2 ...

High Temperature Acidization to Prevent Fines Migration

International Symposium and Exhibition on Formation Damage Control, 2002
Abstract As reservoirs deplete and water production increases, fines production often ensues. The produced fines then cause various forms of damage including screen plugging. To alleviate the plugging, acid washes are pumped onto the screens and then brought back to surface.

Effects of the capillary-entrapped phase on fines migration in porous media

, 2020
A residual gas or oil present during fines migration in porous media can highly affect particle detachment, migration, and straining and thereby decrease rock permeability.

Effects of fines migration on oil displacement by low-salinity water

Journal of Petroleum Science and Engineering, 2019
Enhanced oil recovery by low-salinity waterflooding (LSW) has been shown to result from the combined effect of various physical mechanisms. In this study, laboratory experiments were designed in such a way that only fines migration mechanism remains ...

Developing a methodology to characterize formation damage (pore plugging) due to fines migration in sand control tests

, 2020
Stand-alone screens (SAS) have been widely used in steam assisted gravity drainage (SAGD) operations. Although many researchers investigated the flow performance of SAS through sand control tests, the formation damage (pore plugging) due to fines ...

Soil Pollution due to Migration of Fines

1998
Many toxic chemicals adhere to fine particles; consequently the migration of fines containing contaminants can spread through our environment. There are two primary mechanisms by which the pollution can spread and grow: 1. the mobilization of fine particles carrying contaminants sorbed on their surface and thereby facilitating the transport ...

Chromium and nickel migration study through fine grained soil

Journal of Hazardous Materials, 2009
A comprehensive laboratory-scale investigation was carried out to explore the toxic metal attenuation capacity of a field clay sample collected from adjoining areas of an ash pond site of a Super Thermal Power Plant in West Bengal, India. The existence of two major elements viz., Cr6+ and Ni2+ in excess to permissible limit was observed in soil and ...

Analytical Model for Fines Migration During Water Injection

Transport in Porous Media, 2013
Exact solution is derived for axisymmetric flow during water injection with fine particles detachment, migration, attachment and straining. The solution contains the so-called erosion front described as a weak discontinuity, behind which the mechanical equilibrium of attached particles holds and the dynamic attachment occurs ahead of the front ...
