Abstract

In general, resistivity sounding data interpretation assumes a homogeneous, isotropic and horizontally layered earth model. However, in many field situations these conditions are not valid as the complexity of local geology can originate strong orientation effects caused by lateral inhomogeneities and anisotropy. Under these circumstances it is good practice to keep constant the orientation of the electrode array in use and therefore orientational variation of resistivity data is often ignored. If the strike of concealed formations is known it is possible to choose an array orientation perpendicular to the strike and to obtain further measurements perpendicular to that orientation. This procedure allows a better description of the area but in regions where moderate to strong anisotropic effects exist can lead to results such as the ones shown on Fig.1.
