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.

Fines Migration in Petroleum Reservoirs

1996
Production of petroleum is often hampered by damage to the permeability of reservoir rocks resulting from interaction of injected fluids with the porous rock formation. Fine particles of clays and other minerals are often found attached to the pore walls of reservoir rocks.

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).

Fines migration and compaction in diatomaceous rocks

Journal of Petroleum Science and Engineering, 2014
Abstract Reservoir rocks typically have clay and other fine material attached to pore surfaces. Fines mobilization is advantageous in that the removal of fines from pore walls exposes water-wet rock thereby aiding oil recovery. On the other hand, fines mobilization is deleterious if mobilized particles obstruct pore throats. In this work, waterfloods

Migration of fine-grained multimedia applications

Proceedings of the Posters and Demo Track, 2012
In order to leverage the potential of the device diversity of users, we aim to provide a middleware solution where parts of a multimedia application migrate to different devices and take advantage of more processing power and different I/O capabilities. The middleware is fully designed, and partially implemented and evaluated.

Fine-Grained Failover Using Connection Migration

2018
This paper presents a set of techniques for providing fine-grained failover of long-running connections across a distributed collection of replica servers, and is especially useful for fault-tolerant and load-balanced delivery of streaming media and telephony sessions.

Effect of Nanoparticles on Migrating Fines in Formations

SPE International Oilfield Nanotechnology Conference and Exhibition, 2012
ABSTRACT Fines migration in reservoirs is a serious problem because it gives rise to several problems in hydrocarbon production. Several methods have been proposed and applied to manage this problem but some have failed, some have been ineffective while others consolidate wellbore formations.

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 ...

Modelling Fines Mobilization, Migration and Clogging

Proceedings of SPE European Formation Damage Conference, 1995
Abstract We introduce and discuss a model for fines mobilization, migration and clogging in porous media based on the convection-diffusion equation. Our model contains two fields: The concentration of fine particles deposited on the pore walls and the concentration of fines suspended in the ambient liquid.

Effects of kaolinite in rocks on fines migration

Journal of Natural Gas Science and Engineering, 2017
Abstract A laboratory study has been undertaken on the effect of permeability variation during low-salinity water injection as a function of kaolinite content in the rock. A novel methodology of preparing artificial sand-packs with a given kaolinite fraction has been established.
