In a recent well drilled in Southern Italy, owing to very hostile borehole conditions, several attempts were made to acquire conventional logs in a reservoir characterized by low porosity/fractured quartz-sandstones. This resulted in the availability of different resistivity measurements recorded over a period of time that provided interesting information on the petrophysical properties of the formation. Two sections were drilled (12" 1/4 and 8" 1/2) with fairly conductive mud (60–70 g/l NaCl eq.).
