| 106 | Soil sampling system with sample container rigidly coupled to drive casing | US09018651 | 1998-02-04 | USRE37066E1 | 2001-02-27 | Michael B. Casey; Murray D. Einarson |
| A soil sampling system includes a rig for driving a drive casing, a sample barrel, and sample liners simultaneously into soil to be sampled. The rig includes mechanisms for driving the casing, barrel, and lining in three modes: hydraulic hammer, continuous pressure, and vibration. The three drive mechanisms can be operated singly or in any combination. After the casing, barrel, and liners are advanced a selected depth into the soil, the barrel and liners are removed. The drive casing remains in the soil. New sample liners are put into the sample barrel, and an inner rod is attached to the sample barrel. The sample barrel is then replaced into the drive casing, and extensions are attached to the drive casing. The drive casing, including extensions, and the sample barrels, along with sample liners and inner rod, are driven further down into the soil. The rig also includes a winch that can be coupled to the inner rod or sample barrel so that the casing and/or barrel (including sample liners) can be retrieved from the drive casing. A clamp system allows the sampler to be hydraulically retracted from the ground when sampling is finished. | ||||||

| 109 | Positive latch core barrel apparatus | US212551 | 1998-12-16 | US6089335A | 2000-07-18 | Robert E. Able |
| The drilling apparatus includes a wire line core barrel inner tube assembly movable to a drill string bit end to have its landing ring seat on the drill string landing shoulder and its latches latchingly retain the assembly adjacent the bit end. The assembly includes a fluid bypass channel in a latch body, fluid retention mechanism movable in the latch body to a fluid restriction position to maintain a head of fluid in the drill string even when drilling into a fractured earth formation and an axial outer-open position, a retractor for retaining the latches fully retracted as the assembly moves inward and after the latch body seats on the shoulder, retain the retention mechanism to provide a higher pressure signal than in the restriction position until both latches are in their latch seated position, and thence moves to retain them in their seated position until the retractor is moved outwardly and an overshot coupling device axially movable relative to the retractor and the latch body to through the retractor, move the retention mechanism toward its open position prior to retracting the latch body outwardly of the landing shoulder. The assembly also includes a hollow spindle bearing subassembly fluidly connecting a core receiving tube to the bypass channel to permit more rapid descent of the assembly in the drill string and a valve ball to prevent inward fluid flow through the subassembly. | ||||||
| 110 | Method and apparatus for simultaneous coring and formation evaluation | US732911 | 1996-10-17 | US6006844A | 1999-12-28 | Luc Van Puymbroeck; John W. Harrell; Michael H. Johnson; Pierre E. Collee |
| 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. A significant feature of the apparatus and its operation is the ability to concurrently sense one or more characteristics of the formation surrounding the core barrel in combination with the sensing of one or more such parameters of the core being cut as it proceeds into the inner tube assembly. | ||||||
| 111 | Core drilling latch assembly | US144239 | 1998-08-31 | US5992543A | 1999-11-30 | Frederick J. Soinski; Donald Raymond |
| 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. | ||||||

The insert (24) is always retained within the drive sub (18). Bit segments (22) are carried by the tool (20) to the drive sub (18) and locked in place by the insert (24). The tool (20) can then be withdrawn and the drill (12) operated in the normal manner. To receive the bit segments (22), the tool (20) is relowered into the drill and then withdrawn a short distance to retract the insert (24) so that the bit segments (22) collapse back onto the cradle (176) and can then be withdrawn from the drill (12). | ||||||
| 113 | Vibrator core drilling apparatus | US409194 | 1995-03-23 | US5601152A | 1997-02-11 | Simon J. Harrison |
| A drilling tool, for example a core barrel inner tube assembly, includes a latch body mounting latches for movement into a latch seat to removably retain the assembly adjacent to a drill string bit end and to impart rotary movement to the latch body as the drill string is rotated. A spindle subassembly is connected to the axial inner end of the latch body, to in turn, mount a vibrational subassembly for imparting axial reciprocal movement to a core receiving tube as the drill string is rotated to facilitate entry of core into the tube. The vibrational assembly converts rotary motion of the spindle subassembly to axial reciprocal movement of the core receiving tube while the core receiving tube is not being rotated but is moved axially inwardly over the core. | ||||||
