Abstract
Borehole geophysical logging is a procedure to collect and transmit specific information about the geologic formations penetrated by a well by raising and lowering a set of probes or sondes that contain water-tight instruments in the well. The data collected can be used to determine general formation geology, fracture distribution, vertical borehole flow, and water-yielding capabilities.
