Q:
By using which of the log we can easily differentiate the bed boundary between shale and sandstone?
Answer & Explanation
Answer: B) Gamma-ray log
Explanation: Gamma-ray log can be used to easily differentiate the bed boundary between shale and sandstone. If the gamma ray count is more then it confirms shaly formation otherwise a non-shaly formation. The sonic log gives sonic porosity. The neutron porosity log gives neutron porosity. MSFL is a micro spherically focused log that is used to get Flushed zone resistivity.
