  • Apparatus and method for hard rock sidewall coring of a borehole
    Patent number: 7347284
    Abstract: The present invention is directed to an apparatus and method for coring a borehole in a hard rock sidewall of a well bore in a subterranean formation for testing purposes. The apparatus includes a drive motor for operation down hole, a flexible drive shaft coupled to the drive motor and a coring bit coupled to the flexible drive shaft, such that the coring bit is directly driven by the drive motor. The apparatus also includes a control circuit for controlling advancement of the coring bit into the subterranean formation. The apparatus also includes a rotating carousel for storing multiple core samples. The method includes the steps of activating the drive motor to rotate the output shaft; coupling the output shaft of the drive motor to the flexible drive shaft and rotating the coring bit with the flexible drive shaft.
