One way to be able to identify rocks below the surface, depth, including groundwater aquifer layers is to do geophysical measurements using the schlumberger geoelectric method. This study aims to determine thickness and ...

Coal is a combustible sedimentary rock formed from organic deposits of plant residues and carbon, hydrogen and oxygen elements. Modeling of 3D coal distribution and coal volume calculation plays an important role in ...
