Duration of Transient Pressure of Single- Phase Flow in Porous Media

The present study investigates experimentally two factors affecting the duration of transient pressure of single-phase flow in porous media. The factors that have been investigated are the permeability and flow rate. The experiments included brine flooding in sandstone cores having different permeab...
