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.

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 ...

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 ...

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 ...

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

Transport of polymer particles in a oil-water flow in porous media: enhancing oil recovery [PDF]

, 2018
We study a heuristic, core-scale model for the transport of polymer particles in a two phase (oil and water) porous medium. We are motivated by recent experimental observations which report increased oil recovery when polymers are injected after the ...

A Critical Review of Wettability Alteration of Retrograde Gas Condensate Reservoirs Using Nanoparticles [PDF]

Journal of Chemical and Petroleum Engineering
Condensate and liquid blockage is a serious problem in gas condensate reservoirs as it reduces gas production. There are many methods to solve this problem, however, most of them are temporary or expensive.

Fine Tuning Cell Migration by a Disintegrin and Metalloproteinases [PDF]

Mediators of Inflammation, 2017
Cell migration is an instrumental process involved in organ development, tissue homeostasis, and various physiological processes and also in numerous pathologies. Both basic cell migration and migration towards chemotactic stimulus consist of changes in cell polarity and cytoskeletal rearrangement, cell detachment from, invasion through, and ...
