Determination of rock core - characteristics

摘要

Apparatus for monitoring characteristics of rock cores, the apparatus comprising a clad permanent magnet (5) for generating a magnetic field within a working volume (101) which is sufficiently uniform to enable an NMR experiment to be performed. Conveyors (2) convey rock cores (3) along a path about which the magnet (5) is arranged. The cores pass through the working volume (101) of the magnetic field. A control system (100) carries out an NMR experiment on the portion of the rock core in the working volume.
