A method for measurment of the electrical formation resistivity while auger drilling
By K. SørensenIn environmental studies there is often a demand for such detailed and reliable descriptions of the geological strata that geophysical surface methods must be combined with well-log information. The electrical logging method is a useful tool for providing detailed geological information in the vicinity of a borehole.

Seismic velocity anomalies due to stress concentrations above shallow voids
By T.L. DobeckiIf we were to consider the myriad of features sought by geophysical methods, we might, with some astonishment, arrive at the conclusion that the tunnel and/or void is the most ubiquitous subsurface target. Consider, for example , the wide variety of reasons for seeking to locate tunnels. The reasons may be economic, as would be the case for an enterprising coal mining company, which has bought new mine lands without knowing if, or to what extent, previous, undocumented mining has taken place on the property.
