TL;DR: The Department of Environmental Science and Technology (ENST) is The Place for Ecological Discovery and Natural Solutions! Our primary mission is to educate students on the fundamentals of environmental science, while instilling a deep fascination and intellectual capacity to work in their chosen area of specialization, whether its Natural Resources Management, Ecological Design, Soil and Watershed Science or Environmental Health as mentioned in this paper.
Abstract: The Department of Environmental Science and Technology (ENST) is The Place for Ecological Discovery and Natural Solutions! Our primary mission is to educate students on the fundamentals of environmental science, while instilling a deep fascination and intellectual capacity to work in their chosen area of specialization, whether its Natural Resources Management, Ecological Design, Soil and Watershed Science or Environmental Health. When our students graduate, we want them to be top-notch environmental stewards with a broad framework from which they can advance professionally, personally and socially.

TL;DR: In this article, the authors present a quantitative analysis of temperature effects on the forces exerted on particles and the resultant fines migration in natural reservoirs, and derive a model for the maximum retention concentration and used it to characterize the detachment of multisized particles from rock surfaces.
Abstract: The fluid flow in natural reservoirs mobilizes fine particles. Subsequent migration and straining of the mobilized particles in rocks greatly reduce reservoir permeability and well productivity. This chain of events typically occurs over the temperature ranges of 20-40 degrees C for aquifers and 120-300 degrees C for geothermal reservoirs. However, the present study might be the first to present a quantitative analysis of temperature effects on the forces exerted on particles and of the resultant fines migration. Based on torque balance between electrostatic and drag forces acting on attached fine particles, we derived a model for the maximum retention concentration and used it to characterize the detachment of multisized particles from rock surfaces. Results showed that electrostatic force is far more affected than water viscosity by temperature variation. An analytical model for flow toward wellbore that is subject to fines migration was derived. The experiment-based predictive modeling of the well impedance for a field case showed high agreement with field historical data (coefficient of determination R-2=0.99). It was found that the geothermal reservoirs are more susceptible to fine particle migration than are conventional oilfields and aquifers.

TL;DR: In this article, a study of 16 corefloods with piecewise constant flow rate was performed under increasing flow rate, and it was found that the mobilised particles drift with speeds significantly lower than the carrier fluid velocity, resulting in long permeability stabilisation periods.

TL;DR: In this paper, the analytical model for one-dimensional flow with ionic strength alteration has been derived, and a good adjustment of the permeability and breakthrough concentration data from coreflood test was achieved, and the tuned model coefficients fall in the common ranges.

TL;DR: In this article, the authors derived an analytical model for one dimensional flow with particle release and straining under piecewise-constant increasing velocity, and proposed basic flow equations for single-phase particle transport in porous media with velocity lower than the carrier fluid velocity.
