Movable oil measurement combining dual radio frequency induction and dual induction laterolog measurements

摘要

An exemplary embodiment of the invention includes method for measuring the dielectric constant and resistivity of the invaded zone and the virgin formation in a fluid filled well bore hole. Dual induction laterolog measurements are employed to determined R.sub.t and R.sub.xo. Dual spaced radio frequency dielectric induction log measurements are employed to determine &egr;.sub.t and &egr;.sub.xo. By combining these measurements, a movable oil plot may be obtained in highly resistive formations.
