Fines migration and permeability decline during reservoir depletion coupled with clay swelling due to low-salinity water injection: An analytical study [PDF]

Journal of Petroleum Science and Engineering, 2020
Fines migration is crucial for reservoir permeability, involving both fine particle detachment and re-deposition along the flow channels. Fines migration behavior can either promote or obstruct fluid flow within the reservoir and is crucial for ...

Contrasting the conceptualisation of victims of trafficking for sexual exploitation: a case study of Brazilians in Spain and Portugal [PDF]

, 2014
Despite the significant emphasis given to the trafficking of Brazilians to the sex industry of the Iberian Peninsula, the concepts of “victim of trafficking for sexual exploitation” used in these three countries vary.

Landfill aeration for emission control before and during landfill mining [PDF]

, 2015
The landfill of Modena, in northern Italy, is now crossed by the new high velocity railway line connecting Milan and Bologna. Waste was completely removed from a part of the landfill and a trench for the train line was built. With the aim of facilitating

Formation damage due to fines migration and its remedial methods

Egyptian Journal of Petroleum, 2016
Well productivity decline have been widely observed for gas wells producing the reservoir fines. The phenomenon has been explained by the lifting, migration and subsequent plugging of the pores by the fine particles, finally resulting in permeability ...

Fine particle migration and collection in a wet electrostatic precipitator [PDF]

Journal of the Air & Waste Management Association, 2017
Electrostatic precipitation is considered as an effective technology for fine particle removal. A lab-scale wet electrostatic precipitator (ESP) with wire-to-plate configuration was developed to study particle migration and collection. The performance of the wet ESP was evaluated in terms of the corona discharge characteristics, total removal ...

Quantification of fines migration in block caving mining through laboratory experiments

Results in Engineering
The migration of fines in block caving mining corresponds to the movement of small-size granular material. This material is directed toward drawpoints, causing dilution of valuable mineral and safety concerns due to the formation of cohesive arcs ...

Effect of Various Silica Nanofluids: Reduction of Fines Migrations and Surface Modification of Berea Sandstone

Applied Sciences, 2017
This work is aimed at addressing surface modification of berea sandstone by silica nanofluids (NFs). Three types of nanofluids were used: silica/deionized water (DIW), silica in DIW with a stabilizer fluid (3-Mercaptopropyl Trimethoxysilane) and ...

Klinkenberg-Corrected and Water Permeability Correlation for a Sarawak Carbonate Field

Fluids, 2021
Klinkenberg-corrected permeability (k∞) or water permeability (kw) is an important input parameter for hydrocarbon reservoir simulation studies. The theoretical concept that a core sample’s k∞ is comparable to its kw is flawed and has to be verified ...

Lime stabilisation for earthworks: a UK perspective [PDF]

, 2014
Lime stabilisation is a versatile technique applied during earthworks operations. Modern soil recycling units are much more efficient at pulverising fill material and intermixing the added binder/water than machinery available 20 years ago.

DLVO-based prediction of critical pH for fines migration in sandstone reservoirs

Petroleum Research
Fines migration is a formation damage mechanism that occurs in sandstone formations due to the incompatibility between injected fluids and in situ fluids during various operations such as water flooding, drilling, and completion. Fines migration can lead
