    Electromagnetic imaging of Santos basin constrained by well log induction data
    (Society of Exploration Geophysicists, 2009) Pinto, Vinicius R.; Fontes, Sérgio L.; Ulugergerli, Emin U.
    Summary: In this work, we investigated the resistivity distribution of the subsurface on Santos basin in southeast coast of Brazil. We utilized marine magnetotelluric data and geophysical well log information to construct a resistivity model. Ninety one stations along the three profiles (P01, P02 and P03) covered 270 km long profile. Frequency range is from 10 Hz to 0.0003 Hz approximately. The borehole data consists of four Depth Induction Logs (DIL) located in the region of the magnetotelluric profiles. We show 2 models, one obtained by integration of the 2D magnetotelluric model together with ILD data and other obtained by magnetotelluric data only. In both models the basement topography (? 250 W.m) was delimited clearly in position and depth and some conductive bodies (? 0.75 W.m and ? 3 W.m) were delimited in the central and southeast portion of the profile.
