Three or more multiple figure-eight coils for NMR well-logging measurements with azimuthal directional sensitivity

An NMR method, comprising:

• providing an NMR apparatus having an axial length aligned with a trajectory of a wellbore when disposed in the wellbore, wherein the NMR apparatus comprises:
• an array of three or more figure-eight coil NMR sensors, wherein a first figure-eight coil of the three or more figure-eight coil NMR sensors overlaps a second figure-eight coil of the three or more figure-eight coil NMR sensors at a first axial length position of the NMR apparatus and wherein the second figure-eight coil of the three or more figure-eight coil NMR sensors overlaps a third figure-eight coil of the three or more figure-eight coil NMR sensors at the first axial length position of the NMR apparatus, wherein each of the three or more figure-eight coil NMR sensors has a different azimuthally directional sensitivity and wherein the NMR apparatus comprises three or more pre-amplifiers, and receiver circuitry;
• acquiring an NMR signal from each of the three or more NMR sensors;
• and
• combining the NMR signals prior to passing through the pre-amplifiers and receiver circuitry in order to improve the signal to noise ratio of the total signal from a desired sample space.
