Geophysical Well Logging Borehole Logging Record Equipment Well Logging Tools and Well Borehole log
GEOPHYSICAL WELL LOGGING involves measuring the physical properties of surrounding rocks with a sensor located in a borehole. The record of the measurements as a function of depth is called a well log. Geophysical well logging has become a standard operation in petroleum exploration. Identification of geological formations and formation fluids, correlation between holes, and evaluation of the productive capabilities of reservoir formations are usually the principal objectives. Geophysical well-logging methods include mechanical methods, passive and a number of active electrical methods (including self-potential, resistivity, induction, induced polarization), several nuclear methods (natural γ-ray detection and observations from induced nuclear reactions), acoustic logging, and measurement of magnetic and thermal properties.
