Shale Volume – Larionov Old Rocks

Shale volume refers to the proportion of shale, which is a fine-grained sedimentary rock, present in a given formation. It is an important parameter in the study of subsurface geology, as it affects the rock’s ability to store and transmit fluids such as oil and gas.

The Larionov method is an old but still widely used technique for estimating shale volume in rocks. The Larionov method has some limitations and uncertainties, as it assumes that the rock is composed of only two components (shale and sandstone), which may not always be the case. Nevertheless, it remains a useful tool for estimating shale volume in many geological settings.
