What is Spontaneous Potential Log Overview about?

1. Spontaneous potential (SP) is a natural electrical potential measured in borehole mud relative to a surface reference. 2. SP logs can be used to determine formation water resistivity, identify permeable zones, and provide a qualitative indication of shale content. 3. The SP response is generated by electrochemical and membrane potentials created by salinity differences between formation water and mud filtrate. Shales act as a membrane, affecting the SP.
