dual porosity models

Dual porosity models describe how certain rocks or materials hold fluids in two ways: within larger, connected pores (the matrix) and in smaller, more mobile fractures (the fractures). This approach helps predict fluid movement and storage in complex geological formations, such as shale or fractured reservoirs. By considering both pore types, these models provide more accurate insights into resource extraction and groundwater flow, capturing how fluids can slow down, linger, or flow quickly through different parts of the material. This understanding improves management and recovery strategies in oil, gas, and environmental applications.
