The Dielectric Tool is a pad-type device that uses a microwave signal of 1 gigahertz to measure the Bulk Volume of Water in the flushed zone
In combination with other porosity devices, the BVW value helps to evaluate the amount of movable hydrocarbons in a reservoir. Also the high vertical tool resolution aids in the evaluation of thin beds. The design of the sensor, with two symmetric transmitters and 3 receivers, helps to minimize the effects of rugosity, borehole, and changes in readings due to pad contact. Also the pivot point is in the center of the pad to have a uniform pressure on the formation.
