Direct push electrical conductivity logging is a rapid, cost-effective way to collect a vertical conductivity log without the need for an open borehole. Vertical conductivity data provides information on the distribution of lithological units and soil salinity impacts. Finer matrix grain size as exhibited by clays and silt, generally exhibit a higher conductivity than coarser grained strata (i.e., sands). Salinity impacts arising from elevated levels of inorganic constituents in the subsurface will also have a tendency to increase the conductivity.

An electrical conductivity probe, connected to the bottom of a drill string, is driven into the ground using a hydraulic hammer. The probe is in direct contact with the ground and a resistivity measurement can be obtained. Signals from the probe are fed into a laptop computer and a real time display of downhole conductivity is provided in mS/m.

Hard copies of the logs can be printed in the field if desired. Vertical resolution is excellent at 0.025 m per sample with a maximum data collection rate of 20 samples per second. Thus, a near continuous conductivity log is provided. Data quality is superior to wireline logging tools, as there are no borehole, annulus, or mud effects.
