The HRLA High-Resolution Laterolog Array provides five independent, actively focused, depth- and resolution matched measurements that can resolve the true formation resistivity in thinly bedded and deeply invaded formations. Unprecedented combinability results from the through-wired tool design. The absence of a current return at surface as well as no required use of a bridle greatly improves wellsite efficiency.

The standard AIT-B and AIT-C tools are used in moderate-environment wellbore conditions to measure the true resistivity of geologic formations. AIT measurement of conductivity as a function of both depth and distance from the borehole has revolutionized induction logging by increasing the depth of investigation of the measured signal concurrent with reducing the vertical resolution from 4 to 2 ft [1.22 to 0.61 m] and to 1 ft [0.30 m] in smooth wellbores.
