Analytical Modelling of Low-salinity Waterflooding with Fines Migration
Proceedings, 2016Low-salinity waterflood is presently one of the most cost-effective EOR methods. The governing system of equations for oil and water flow with changing water salinity is derived. So-called mechanistic model is developed. This model accounts for two EOR factors: A) fines migration, which is induced by salinity variation and reduces the relative ...

Modified Mathematical Model for Fines Migration in Oilfields
All Days, 2011Abstract Permeability decline during corefloods with varying water composition, especially with low salinity water, has been widely reported in the literature. It has often been explained by the lifting, migration and subsequent plugging of pores by fine particles, which has been observed in numerous core flood tests with altered water ...

WATER‐SENSITIVITY AND MIGRATION OF FINES IN THE HOPEMAN SANDSTONE
Journal of Petroleum Geology, 1984Water‐sensitivity tests have been performed on samples of the Triassic Hopeman Sandstone from Clashach Quarry near Elgin in Scotland. Despite the apparent lack of clay minerals in the samples, the permeability of core plugs to NaCl and KCl brines decreases with progressive volume of efflunent, and drops dramatically when distilled water is flushed ...

Fines Migration in Aquifers and Oilfields: Laboratory and Mathematical Modelling
2018Migration of natural reservoir fines is one of the main causes of formation damage in oil and gas fields. Yet, fines migration can be employed for enhancing reservoir sweep and water production control. Permeability decline due to fine particles’ detachment from reservoir rocks, mobilisation, migration and straining has been widely reported in the ...

Quantitative Theory for Fines Migration and Formation Damage
SPE International Symposium and Exhibition on Formation Damage Control, 2010Abstract Particle detachment from the matrix during suspension transport in porous media was widely observed for laboratory corefloods and flows in natural reservoirs. A new mathematical model for detachment of particles is based on mechanical equilibrium of a particle positioned on the internal cake in the pore space. The torque balance

Entrapment or Piping of Fines During Migration
1998In the previous chapters we have discussed the release of fine particles from the pore surface to the liquid stream flowing through the porous medium. These fine particles while flowing with the liquid phase, can either readhere to the pore surface or flow without capture or get entrapped at the pore constrictions.

Prediction of Fines Migration through Core Testing
SPE Annual Technical Conference and Exhibition, 2017AbstractFines migration is a commonly observed phenomenon in oil and gas wells, but often difficult to duplicate in the laboratory. A suite of labs tests was conducted to gauge the effect that different test conditions have on fines migration and to improve fines migration prediction through updated test strategies.

An Experimental Investigation of Fines Migration in Porous Media
SPE Annual Technical Conference and Exhibition, 1983ABSTRACT Permeability decline in argillaceous sandstone formations has tendered a broad spectrum of explanations and related remedial treatments. This decline has often been attributed to the mobilization, migration, and plugging of fine particles in the formation pore spaces.

Injectivity formation damage due to fines migration
The APPEA Journal, 2018Formation damage by fines migration during low-salinity water injection can greatly affect field-scale waterflooding projects. In this paper, we present the basic governing equations for single-phase flow with detachment, migration and straining of natural reservoir fines.

Fine-Scaled Orientation Changes in Migrating Shorebirds
Ardea, 2012Flight directions and routes of migrating birds are determined by the birds' compass orientation, but also by effects of wind, social influence, responses to topography and landmarks, and to navigation cues. We investigated the orientation and routes taken by arctic shorebirds during autumn migration in southern Sweden at three different sites situated
