                         Paran{\'a} basin, SE Brazil. In this paper, we describe an 
                         upgrade in the methodology applied for the development of the 1D 
                         geoelectric model for the Bipole I south electrode site, and for 
                         the final adjustment of this model, based on the commissioning 
                         data. The preliminary model is based on data acquired with shallow 
                         (electroresistivity) and deep (magnetotelluric) geophysical 
                         soundings. Both soundings are affected by distortions caused by 
                         galvanic deviations, due to local surficial inhomogeneities, which 
                         produce a constant vertical deviation in the logspace of the whole 
                         apparent resistivity curves. For the development of the design 
                         geoelectric model, a first adjustment of the set of apparent 
                         resistivity curves is applied. After the electrodes commissioning 
                         an iterative calculation is applied for the simultaneous 
                         adjustment of the electrode resistance and of the geoelectric 
                         model.",
