Methods :: Borehole Geophysics :: Borehole Logging

Borehole logging provides in situ measurements of the physical properties of the ground water and matrix, such as resistivity, temperature, flow direction and rate, velocity, dip and strike of fault and joints, clay content, mineral content, etc. The logging probes include natural gamma, caliper, fluid resistivity/temperature, self potential, single point resistance, normal resistivity, induced polarization, magnetic susceptibility, acoustic velocity, optical/acoustic borehole imagery, electromagnetic induction, flow meter, and borehole deviation.
