terms:deep_propagation_log
A well log that provides the resistivity and dielectric constant of the formation. The deep propagation tool (DPT) radiates electromagnetic energy into the formation surrounding the wellbore. Measurements of the attenuation and velocity of this electromagnetic wave provide values to determine the resistivity and dielectric constant of the formation. The tool operates at a frequency in the tens of megahertz range and measures signal level and relative phase at four receivers. Compare electromagnetic propagation tool.
