Blockedwettedness

Blockedwettedness is a phenomenon observed in porous materials that influences fluid flow and transport processes. It describes a condition where a portion of the pore space within a material becomes permanently or semi-permanently saturated with a wetting fluid, such as water. This saturation can impede the subsequent movement of non-wetting fluids, like oil or gas, through the material.

The extent and persistence of blockedwettedness depend on several factors. These include the properties of the porous medium, such as pore size distribution, pore connectivity, and surface wettability. The characteristics of the fluids involved, specifically their interfacial tension and viscosity, also play a crucial role. Additionally, the history of fluid saturation and displacement within the material can significantly influence the development of blockedwettedness.

This phenomenon has important implications in various fields. In petroleum engineering, it can affect oil recovery processes, where water initially present or injected might block oil pathways. In hydrology and hydrogeology, it can influence groundwater flow and contaminant transport. In soil science, blockedwettedness can impact water infiltration and nutrient availability. Understanding blockedwettedness is therefore essential for accurately modeling and predicting fluid behavior in porous media across diverse scientific and engineering disciplines. Research in this area often involves experimental techniques and numerical simulations to quantify the degree of pore occupancy and its impact on fluid displacement.
