3 Sensor Caliper

Application

The Three-Sensor Caliper is a downhole, production logging tool used to measure the inside diameter of a wellbore. Three sensors, connected to three equally spaced arms, measure the diameter of the well. These measurements allow operators to gather information regarding the condition of the well. Data from the tool indicates the presence and inside diameter of restrictions or out-of-round conditions in a wellbore.

The tool is designed to pass from a large diameter to a smaller diameter while logging down. It can also log up to a small diameter restriction without locking up the arms.
