Effects of fines migration and reservoir heterogeneity on well productivity: analytical model and field cases

Journal of energy resources technology
Formation damage due to fines migration after water breakthrough during oil and gas production results in significant well productivity decline. A recent study derived an analytical model for fines migration during commingled water-oil production in ...

Predictive Modelling of CO2 Injectivity Impairment due to Salt Precipitation and Fines Migration During Sequestration

, 2021
Recent studies indicated that reactive interactions between carbon dioxide (CO2), brine, and rock during CO2 sequestration can cause salt precipitation and fines migration.

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.

Wettability of sandstone rocks and their mineral components during CO2 injection in aquifers: Implications for fines migration

, 2020
This paper presents CO2-brine wettability of sandstones and minerals composing the sandstones. The measured contact angles are used further to analyse the effect of wettability on fines migration during CO2 injection. Limited data are available to assess

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.

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 ...

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 ...
