Magnetic Resonance Imaging Logging

Magnetic Resonance Imaging Logging service measures several factors that influence the ability of a well to produce commercial quantities of oil or gas. One of the fundamental measurements is the total fluid-filled porosity. The measurement is fluids only; the rock matrix is invisible to the tool. The total porosity measurement is the sum of cay bound water, irreducible water saturation, and free fluid volumes. These measurements are critical in identifying low resistivity pay, where high immovable water volumes may be causing productive zones to be overlooked. The logging tool derives a permeability measurement and is able to determine fluid type, pick fluid contacts, and detect changes in oil viscosity.
