Question

A rock can be highly permeable but also non-porous. True False

Answer 1

Answer;

The above statement is false

Explanation;

• 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.
