formação de imagem baseada em medições de voltagem de resistor duplo de 4 terminais

Measurements made by a four terminal resistivity imaging tool in a borehole using a voltage measurement device with two different input impedances. From the two measurements, formation resistivity is determined with minimal sensitivity to standoff.
