vekshin1
<h3><u>Answer;</u></h3>

The above statement is <u>false</u>

<h3><u>Explanation</u>;</h3>
  • Rocks have different porosity and permeability characteristics, which means that water does not move around the same way in all rocks below ground.
  • Permeability greater than 250 mD are considered very good, while permeability less than 1 mD are considered poor.
  • Low porosity normally results in low permeability, but high porosity does not necessarily imply high permeability. It is possible to have a highly porous rock with little or no interconnections between pores.
