Abstract

Nuclear magnetic resonance well logging apparatus and a method of use for geophy-sical examination of a bore hole as the bare hole is drilled. The apparatus is connected to the drill bit (36) to follow it through the bore hole as the bore hole is formed. The apparatus comprises a resilient, tubular, permanent magnet (46),for generating a static magnetic field in the region of portion of the bore hole adjacent the apparatus, which region includes ma-terials sought to be analyzed, an antenna (48) mounted an the magnet and connected to as-sociated circuitry for exciting nuclei of the materials sought to be analyzed in the region, and a receiver connected to the antenna for receiving nuclear magnetic resonance signals from the excited nuclei and for providing an output signal indicative of properties of the materials sought to be analyzed.
