Is conglomerate a permeable or impermeable?

Conglomerate is generally considered a permeable rock, meaning it can allow fluids, such as water or oil, to pass through its pores and spaces between the clasts (rocks or minerals) that make up the rock. However, the degree of permeability can vary depending on factors like the size of the clasts, the amount of cementing material, and the overall porosity of the rock. In some cases, if a conglomerate is heavily cemented, it could exhibit lower permeability.
