Dual Laterolog Tool (EDLT) The Dual Laterolog Tool (EDLT) 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 be able to distinguish visually and accurately any permeable formation, locating oil and water formation.
