Sondagem elétrica vertical aplicada em pesquisa hidrogeológica na bacia do Parecis, MT

The research was carried out in Lucas do Rio Verde city, Mato Grosso State, Brazil, to estimate the depth and thickness of hydrogeological units. This parameter was estimated using vertical electrical sounding (VES), with AB/2 maximum of 2000 m. The results show that the average depth and thickness of Utiariti aquifer are respectively 13 m and 90 m, the Saltos das Nuvens Formation has average depth of 103 m and thickness greater than 600 m. Only the portion of the Utiariti aquifer consisted essentially of fine to medium sandstone was defined very precisely by the VESs. Geological data from the well, used in the interpretation of VES allowed greater reliability on the obtained results

Aplicação de sondagem elétrica vertical na estimativa do topo e da espessura de unidades geológicas da bacia do Paraná na cidade de Rondonópolis-MT

The research was carried out in Rondonopolis city, Mato Grosso State, Brazil, to estimate the depth and thickness of geological formations occurring in the area, using vertical electrical sounding (VES). The results show that the maximum thickness of Ponta Grossa Formation is 63 m, and that the joint thickness of Furnas/Ponta Grossa transition and the Furnas Formation is greater to 700 m. The thickness of Furnas/Ponta Grossa transition could not be estimated due to lack of evidence in VES curves. It was observed a considerable litological variation in Furnas Formation. Geological data from wells used in the interpretation of VES allows greater reliability for the obtained results.
