Dual Laterolog Logging Tool (EDLT70) The Dual Laterolog Logging Tool (EDLT70) provides two resistivity measurements, a Shallow reading which investigates the formation near the borehole and a Deep reading which measures farther out in the formation where it’s less disturbed by drilling fluid. By analyzing this information combined with other logging curves, the geologist will accurately and visually distinguish any permeable formation, locate oil and water formation.
