Paper presented at the 2013 SEG Annual Meeting, September 22–27, 2013
Paper Number: SEG-2013-1085
... Summary We present an algorithm for the joint inversion of surface wave, P-wave refraction ad apparent resistivity data. The algorithm solves the model parameters imposing the same earth structure as well as the respect of some petrophysical relationships. P- and S-wave velocities are linked...

... influence on the readings. In the case of a four-electrode measurement the apparent resistivity is commonly determined on the base of a semi-spherical distribution of the current in the concrete which does not fully reflect the real situation. For surface layers a cylindrical approach is presented...
