  • Core drilling latch assembly
    Patent number: 6019181
    Abstract: A core drilling latch assembly for use in terrestrial core drilling operations. The latch assembly incorporates features and elements which affect the flow of drilling fluids past the latch assembly and toward the drill bit, depending upon whether the latch assembly has contacted the landing ring in the drill string and whether the latch assembly has locked in place within the string. Accordingly, the latch assembly signals the drilling crew by pressure fluctuations when the latch assembly is in proper position within the drill string, and whether it is locked in position.
    Type: Grant

  • Wireline core barrel
    Patent number: 4466497
    Abstract: A wire line core barrel for retrieving a core sample within a drill string. The wire line core barrel includes a conventional inner tube and also includes a generally cylindrically shaped retrieving assembly disposed above a generally cylindrical elongate body having a fluted periphery comprising a plurality of longitudinal ribs and longitudinal channels. Means for attaching the inner tube assembly to the drill string are mounted on the ribs of the elongate body. The channels of the elongate body provide a straight, longitudinal passageway for fluids flowing through the drill string.
