This lesson covers the concept of flow through porous media, focusing on the interception of suspended solids and the implications of fines migration. It explains how permeability changes due to the deposition of solids and the impact of this on environmental flow in soil science, deep filtration, and sandstone reservoirs. The lesson also discusses the continuity equation, the concept of volumetric deposition rate, and the effect of particle concentration on permeability. It further explores the relationship between permeability and cumulative flow, and how this affects the pressure drop in a system. For instance, in a deep filtration process, as more particles are deposited, the permeability decreases, affecting the pressure drop.

- The interception of suspended solids in a porous medium can lead to changes in permeability due to the deposition of solids.
- The continuity equation and the concept of volumetric deposition rate are crucial in understanding how particle concentration affects permeability.
- The relationship between permeability and cumulative flow is essential in predicting the pressure drop in a system.
- In a deep filtration process, as more particles are deposited, the permeability decreases, which in turn affects the pressure drop.
