Claim 1

THE METHOD OF DETECTING THE PRESENCE OF PARTICULAR HYDROGENOUS FLUIDS IN A HETEROGENEOUS MIXTURE OF A PLURALITY OF HYDROGENEOUS FLUIDS IN AN EARTH FORMATION TRAVERSED BY A WELL BORE WHICH COMPRISES THE STEPS OF ESTABLISHING A POLARIZATION CONDITION OF PROTONS IN FLUIDS WITHIN AND SURROUNDING SAID WELL BORE, INTERRUPTING SAID POLARIZATION CONDITION TO PERMIT SAID PROTONS TO PRECESS IN PHASE UNDER THE INFLUENCE OF THE EARTH''S MAGNETIC FIELD. MEASURING A CHARACTERISTIC OF THE RELAXATION O SAID PRECESSING PROTONS WITHIN AND SURROUNDING SAID WELL BORE, THEN ESTABLISHING AT LEAST ANOTHER DIFFERENT POLARIZATION CONDITION OF SAID PROTONS IN SAID FLUIDS INTERRUPTING SAID DIFFERENT POLARIZATION CONDITION TO PERMIT A SECOND-IN-PHASE PERCESSION OF SAID PROTONS UNDER THE INFLUENCE OF THE EARTH''S MAGNETIC FIELD, MEASURING A SIMILAR CHARACTERISTIC OF THE RELAXATION OF SAID PROTONS FROM SAID DIFFERENT POLARIZATION, AND COMPARING SAID SIMILAR CHARACTERISTICS OF SAID MEASURED RELAXATIONS OF SAID HYDROGENOUS FLUIDSS TO DETECT VARIATIONS IN THE RELAXATION WITH VARIATION IN POLARIZATION AS A DIRECT INDICATION OF THE PARTICULAR HYDROGENOUS FLUIDS SUBJECT TO SAID POLARIZATION CONDITION.
