Shale Volume
Shale volumen is a fundamental value to evaluate the quality of a reservoir rock.
According to the shale volume that a reservoir rock has, it will be determined how exploitable a reservoir is or not.
There are different methods to calculate shale volume, where we can name some of these equations: Larionov, Larionov- old rocks, Steiber, Clavier. Some of these equations use the gamma ray well log values, and some of them use values from spontaneous potential (SP) well logging tool.
Also, this value is used to make shale correction for porosity values derived from different well logging tools, so we can have a more reliable porosity value.
From the different links of this section, you can find the different equations used to calculate shale volume:
You can calculate the following Shale Volume Equations:
