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 ...

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 ...

Quantification of fines migration in block caving mining through laboratory experiments
Results in EngineeringThe 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 ResearchFines 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

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 ...

A Critical Review of Wettability Alteration of Retrograde Gas Condensate Reservoirs Using Nanoparticles [PDF]
Journal of Chemical and Petroleum EngineeringCondensate 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.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer
Molecular Oncology, EarlyView.Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...
