Shale Volume - SP

From the spontaneous potential (SP) well log, it is possible to calculate shale volume from 2 different equations. The first expression is the following:

Where:
• Vshale= volume of shale
• PSP= pseudostatic spontaneous potential (maximum SP of shaly formation)
• SSP= static spontaneous potential of a nearby thick clean sand

Calculate Shale Volume (Vsh)-SP
PSP: mV		SSP: mV

The other alternative to calculate shale volume is the following one:

Where:
• SPshale= value of SP in a shale (usually assumed to be zero)

Calculate Vsh - SP
PSP: mV		SSP: mV
SPshale: mV
