Methods for investigating the properties of fluid (materials) within porous media

Claim 1

A METHOD FOR LOGGING AN EARTH FORMATION FROM WITHIN A WELL BORE PENETRATING SAID EARTH FORMATION TO DETERMINE THE PRESENCE AND MOLECULAR STRUCTURE OF FLUID MATERALS IN SAID EARTH FORMATION COMPRISING THE STEPS OF: (A) DETERMING THE RELAZATION RATE FOR POLARIZABLE MATERIALS WITHIN SAID EARTH FORMATION BY PROVIDING AN INITIAL POLARIZATION OF SAID POLARIZABLE MATERIALS, ESTABLISHING A FIRST RELAXATION FIELD IN SAID EARTH FORMATION FOR SAID POLARIZED MATERIALS, INTERRUPTING SAID RELAXATION FIELD AND INITIATING PRECESSION OF SAID POLARIZED MATERIALS IN THE EARTH''S MAGNETIC FIELD, SAID ESTABLISHING AND INTERRUPTING STEPS BEING MORE THAN ONE ESTABLISHMENT OF SAID RELAXATION FIELD EACH ONE FOLLOWING A REESTABLISHMENT OF SAID INITIAL POLARIZATION AND EACH FOLLOWED BY AN INTERRUPTION OF SAID RELAXATION FIELD, EACH OF SAID MORE THAN ONE ESTABLISHMENT BEING AT THE SAME FIELD STRENGTH BUT FOR A LONGER TIME DURATION THAN THE NEXT PRECEDING ESTABLISHMENT, DETECTING SPIN MAGNETIC INDUCTION SIGNALS FROM SAID PRECESSING POLARIZED MATERIALS AFTER EACH INTERRUPTION OF SAID RELAXATION FIELD, AND DETERMINING FROM SAID DETECTED PRECESSIONAL SIGNALS THE RELAXATION RATE FOR SAID POLARIZED MATERIALS WITHIN THE FORMATION IN RESPONSE TO SAID FIRST RELAXATION FIELD STRENGTH, (B) REPEALING SAID RELAXATION RATE DETERMINATION STEPS BY PROVIDING THE SAME INITIAL POLARIZATION OF SAID POLARIZABLE MATERIALS FOLLOWED BY A SECOND RELAXATION FIELD, SAID SECOND RELAXATION FIELD DIFFERING FROM SAID FIRST RELAXATION FIELD IN FIELD STRENGTH, SAID SECOND RELAXATION FIELD BEING ESTABLISHED FOR THE SAME NUMBER OF ESTABLISHMENTS AS SAID FIRST RELAXATION FIELD AND EACH ESTABLISHMENT BEING FOR THE SAME TIME DURATION AS SAID ESTABLISHMENTS OF SAID FIRST RELAXATION FIELD, DETERMINING THE RELAXATION RATE FOR SAID POLARIZED MATERIALS IN RESPONSE TO SAID SECOND RELAXATION FIELD STRENGTH, (C) COMPARING SAID DETERMINED RELAXATION RATES TO IDENTIFY A DIFFERENCE IN SAID DETERMINED RELAXATION RATES APPARENTLY DEPENDENT ON THE DIFFERENCE IN SAID FIRST AND SECOND RELAXATION FIELD STRENGTH, (D) AND CORRELATING SAID IDENTIFIED RELAXATION FIELD STRENGTH DEPENDENCY INDICATED BY DIFFERENCES IN SAID RELAXATION RATES WITH KNOWN GEOLOGICAL MATERIALS CAPABLE OF CAUSING SAID DIFFERENCES WITHIN SAID FORMATION PENTRATED BY SAID WELL BORE TO DETERMINE THE PRESENCE AND MOLECULAR STRUCTURE OF SAID FLUID MATERIALS.
