Abstract

um sistema para medir características elétricas de uma formação de terra inclui um transportador configurado para ser disposto em uma formação de terra e um conjunto de medição indutiva incluindo uma antena configurada para gerar um campo magnético oscilante na formação de terra e medir uma resistividade da formação detectando um sinal em resposta a correntes induzidas na formação. o sistema também inclui um conjunto de medição capacitiva incluindo um eletrodo de medição capacitiva configurado para detectar um sinal em resposta a uma corrente de medição injetada na formação, o eletrodo de medição capacitiva disposto entre a antena e a formação e em um caminho do campo magnético, o eletrodo de medição capacitiva formado de uma pluralidade de eletrodos constituintes que são isolados eletricamente uns dos outros de modo a impedir indução de correntes de fuga através da pluralidade de eletrodos.
