The clamp assembly rigidly secures each of the vibratory devices to one of a plurality of predetermined angularly spaced locations about the caisson. The suspension assembly connects the vibratory devices to the crane assembly such that transmission of vibratory forces from the vibratory devices to the crane assembly is inhibited. The timing system operatively connects the plurality of vibratory devices to synchronize the vibratory forces generated thereby.

  • Patent number: 6732818
    Abstract: A device for preserving the orientation of a core is described. A core barrel is attached to a rotatable orienting rod. A plurality of projections are located on an inner surface of the core barrel. Three projections are grouped together and opposite from a fourth projection. A ratchet assembly is included at an end of the rotatable orienting rod opposite from the core barrel. The ratchet assembly includes a first body, to which the rotatable orienting rod is attached, a plate, a second body, and a biasing mechanism. A turning rod is mounted on the plate, which is located between the two bodies. The plate and the second body each have teeth which intermesh, but which slip if a clog in the core barrel inhibits rotation of the rotatable orienting rod.

  • Patent number: 6659196
    Abstract: An upper end (10) for the inner tube of a core drill has a marking device comprising a pendulum (350) or hard ball (30) which runs in a circumferential track (24). The marking device adapted to be carried within a tubular upper end casing (12) which surrounds a spindle (11) which supports the inner tube of the drill. An indent washer (25) is positionable below the marking device and is oriented relative to the casing. When the upper end (10) is lifted, the marking device is driven into contact with the washer (25) and makes an impression. The orientation of the impression reveals the orientation of the drill. The impressioned washer (25) can be used to assist in noting or marking the core orientation after the drill is removed from the earth.

  • Patent number: 6386026
    Abstract: A sample catcher comprises an inclined sampling screw conveyor which intercepts a continuous stream of drill cuttings from a shaker. A vaned metering rotor accepts a plurality of discrete samples from adjacent the conveyor's discharge. The vaned rotor is rotated at a lag rate proportional to the rate of penetration at the time the stream of cuttings with drilled. The plurality of discrete samples are discharged as a substantially continuous sample stream which is directed through a second conveyor to one or more analytical instruments. Further, the sample stream can be directed to a sample bag carousel which is index advanced for associating the bag contents with the drilling. The apparatus enables a method of analyzing cutting samples which correlate to the cuttings when drilled and in a process which is continuous.

  • Patent number: 6006844
    Abstract: A core barrel having an inner tube for coring and, alternately, a center plug assembly for closing the throat of the core bit at the bottom of the assembly for drilling in lieu of coring. The inner tube assembly and plug assembly are disposable and retrievable through the drill string on a wireline using an overshot. The core bit is of a stabilized, preferably anti-whirl, design and may be a low-invasion core bit used in cooperation with a low-invasion coring shoe. A logging tool and data transmission assembly may be incorporated in the plug assembly for logging while drilling. Alternatively, sensors for logging borehole parameters and a data transmission assembly may be incorporated in the inner tube assembly, in the wall of the core barrel, above the core barrel, or in a combination of such locations.

  • Patent number: 5445228
    Abstract: A tool for obtaining samples of the formation surrounding the wellbore, and method of obtaining such samples, is disclosed. The tool is implemented within a sub in a bottomhole assembly, preferably within side-pocket mandrels in the outer surface of drill collar pipe. The tool includes a series of sampling bits that may be fired into the surrounding formation by the activation of an explosive charge, and also includes an electronic unit for detecting a signal from the surface and activating the charge in response thereto. The signal may be communicated by way of mud-pulse telemetry, or by any other known telemetry technique. Separate groups of sampling bits, with separate switch and power units, may be provided to provide redundant operation; a decoder is included in this alternative, to allow for selection of one of the groups.

  • Patent number: 5105894
    Abstract: A method and apparatus for determining the location in space of a formation sample is set forth. This involves a tool which is typically run on a wireline in a well, the tool supporting orthogonal positioned magnetometers and similar orthogonal accelerometers for measuring movement of the tool along the well borehole whereby components of the magnetic field and gravity field are measured to enable determination of the well in space. The tool supports an axially positioned centrally located core cutting apparatus and a laterally projecting plug cutting apparatus; scribe marks formed on the formation samples orient the samples relative to the tool and the tool is located in space from the above mentioned measurements so that the position of formation samples can be determined.

  • Patent number: 4860836
    Abstract: A system for eliminating the need for one or more mud loggers on a drilling rig keeps track of the travel of drilling mud injected into the bottom of the well as it moves to the surface of the well with entrapped drill cuttings and gas so that for mud reaching the surface of the well, the system knows at what depth in the well the mud was injected. The system indicates to drill rig personnel when mud from preselected well depths reach the surface of the well and when to collect samples of drill cuttings strained from the mud in order to have the required samples representative of the preselected well depths. The system monitors the performance of well personnel in collecting samples by monitoring the time it takes to collect a sample after the indication that the sample should be collected.

    Abstract: Sampling bullets of the type which are fired into rock formation surrounding a wellbore. The core sampling bullet includes an internal core barrel which is defined in part by a core receiving sleeve releasably secured within the bullet structure. Following bullet retrieval, the bullet is disassembled thereby permitting rearward removal of the core sleeve with core entrapped therein. Following extraction from the bullet, the core sleeve protects the core during handling and testing. The removed core sleeve is further closed by end cap members to further secure the core against contamination and against further loss of gas in core sample prior to testing. The bullet construction also provides for efficiency of hydraulic venting during firing and provides efficiently for bullet with core removal by means of one or more cables. Core orientation is also achieved.
