Abstract
"MéTODO E APARELHO PARA ESTUDO DE RESISTIVIDADE DE UMA FORMAçãO GEOLóGICA EM TORNO DE UM FURO DE POçO EQUIPADO COM UM REVESTIMENTO METáLICO". A invenção refere-se a um método e um aparelho para estudo da resistividade de uma formação geológica em torno de um furo de poço equipado com um revestimento metálico. Uma corrente elétrica é aplicada ao revestimento para causar uma fuga de corrente para o interior da referida formação num determinado nível, e a referida corrente é derivada por um circuito de realimentação em contato com o revestimento em ambos os lados do nível de medição, o referido circuito sendo organizado de forma a assegurar que a corrente que flui ao longo do revestimento no referido nível tenha um valor reduzido em comparação com a corrente derivada, sendo determinada a diferença entre as quedas de voltagem nas seções adjacentes de revestimento situadas em ambos os lados do nível de medição, e sendo daí deduzida a corrente (Ifor) de fuga.
