Fines migration in porous media

AIChE Journal, 1987
AbstractA model developed by Sharma and Yortsos (1987a) is applied to the processes of fines migration and fines injection in a porous medium. The first is a problem frequently encountered in oil reservoirs when release of fines is triggered by physicochemical interactions of the porous formation with the injected fluids. The second may be a problem in

Formation Damage by Fines Breakage and Migration

SPE International Conference and Exhibition on Formation Damage Control, 2022
Abstract Fines migration is one of the most drastic causes for formation damage - the detached clays migrate and impairs well productivity. Two types of damaging clays are encountered in petroleum reservoirs: authigenic clays that grew on the grain surfaces during geological times, and detrital clays that have been broken off the grains ...

Fines migration in geothermal reservoirs: Laboratory and mathematical modelling

Geothermics, 2019
Fines migration with consequent well productivity reduction is a well-known phenomenon occurring during exploitation of geothermal reservoirs. Laboratory corefloods with piecewise constant decreasing ionic strength have been performed with measurements of the pressure drop along the core and the accumulated effluent particle concentration.

Well Productivity Impairment Due to Fines Migration

SPE International Conference and Exhibition on Formation Damage Control, 2018
Abstract Compressibility needs to be accounted for when estimating productivity decline in closed gas and oil reservoirs, and in closed aquifers. Previous works derived an analytical model and well index for inflow performance accompanied by fines migration and consequent permeability damage for incompressible flow towards well.

Fines migration in two-phase flow

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1990
Summary Fines migration is a recognized source of permeability reduction andproductivity decline in consolidated and unconsolidated cores. Previousinvestigations have shown that salinity, flow rate, pH, and temperaturesignificantly affect the process.

Formation Damage by Fines Migration

2018
One of the widely spread causes of reservoir formation damage is fines migration. Migration of natural reservoir fines occurs during commingled production of oil or gas with low-salinity water, during high-rate production or injection, with low-salinity waterflooding and its combinations with enhancd oil recovery (EOR).

True-amplitude migration taking fine layering into account

Geophysics, 1993
Abstract The central process in wave-equation--based depth migration is inverse wavefield extrapolation. The commonly applied matched filter approach to inverse wavefield extrapolation ignores the angle-dependent amplitude and phase distortions that are related to fine layering.
