.... However, uncontrolled spurt and filtrate invasion are detrimental because they reduce the permeability of the formation. Mud composition, formation rock's permeability and porosity, and temperature can influence both spurt and filtrate invasion. The sizes of mud solids relative to the average pore size...

... by precipitated salts. A tortuosity factor was incorporated to account for the tortuous path taken by fluids in porous media. A sensitivity study was performed to assess the effects of parameters such as brine salinity, initial permeability, injection flowrate and porosity on injectivity loss. The model can...

... that crushed zone damage is dominated by pore compaction near the tunnel edge, which has a characteristic signature in terms of the radial variation of porosity and pore-perimeter to surface-area ratio. Analysis of the spatial distribution of permeability suggests that flow efficiency is controlled by a low...

We first perform an experimental study of suspension flow into sintered glass bead plugs and measure changes in porosity and permeability. Specifically, glass bead suspensions of known mono- and poly- disperse...
