ABSTRACT:
A chip sampler including a sampler barrel aligned with the stern of a drill pipe to form an extended annular space to receive cuttings from a drilled hole. The sampler barrel carries a reject port in communication with the entire annular space and an access port disposed below the reject port. The access port receives a sample extractor that includes a downwardly directed nose opening which extends into a predetermined proportion of the extended annular space. A reasonably sized representative sample of the cuttings travelling up the extended annular space enter the nose opening and are received into a detachable sample container.
