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 ...

The effects of chemical composition of fines and nanoparticles on inhibition of formation damage caused by fines migration: Insights through a simplex-centroid mixture design of experiments

, 2021
Fines migration in the reservoir can leads to damage associated with the mobilization of particles and their posterior accumulation in throat pores, producing obstructions in the flow of fluids, resulting in a decrease of reservoir permeability.

A Novel Method To Assess Stimulation of Sandstone Cores Damaged by Fines Migration

SPE Journal, 2021
Sandstone stimulation remains challenging because of formation heterogeneity and the sensitivity of clay minerals to acids such as hydrochloric acid (HCl) and mud acid [HCL/hydrofluoric acid (HF)].

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.

Coal Fines Migration, Deposition, and Output Simulation during Drainage Stage in Coalbed Methane Production

, 2021
Fracture and cleats development controls the permeability of coal reservoirs, while the migration of coal fines can block fractures and affect coalbed methane (CBM) production performance.

Fines Migration in Two-Phase Flow

Journal of Petroleum Technology, 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.

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.

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

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.
