... Abstract This paper investigates the suspended particle retention rate and permeability damage in porous sandstone during produced water injection process. The data used in this study was obtained from one-dimensional constant rate injection tests in which both the effluent concentration...

... Abstract Despite the economics and environmental benefits of PWRI projects, the permeability reduction due to deposited particles is a persistent problem. Various models for permeability damage calculation are available. Most of them are based on 1D laboratory parameters and have...

... their contributions to overall (upscaled) mass transport is a complex and time consuming procedure. The paper presents numerical diffusion models in varying coal particles and investigates transport mechanisms. For this purpose, the coal particle is represented as a microporous solid penetrated by a network of larger...

... Abstract An accurate calculation of a slurry flow in a fracture is important for fracture designing. A model taking into account particle dynamics on micro-level has been developed. The model shows that the slurry dynamics to a significant extent is governed by particle fluctuations generated...

... of produced water requiring disposal increase significantly. Re-injecting produced water is an attractive, environmentally sound solution to water disposal problems but entails the risk of poor injectivity. Produced water normally contains varying concentrations of particles, which have a direct effect...

... of improving tool design and extending its life. History of Erosion Research Erosion (i.e., a form of wear) occurs when fluid containing solid particles impacts a solid surface. The intensity of erosion is commonly measured as a specific weight loss (rate of material removal from the surface) and expressed...
