| 61 | Self-contained apparatus and method for determining the static and dynamic loading characteristics of a soil bed | US745730 | 1991-08-16 | US5125266A | 1992-06-30 | Wayne B. Ingram; Byron W. Porter |
| The invention comprises an improved self-contained, environmentally isolated, multi-parametric measuring apparatus and method for sampling and determining the dynamic loading characteristics of a soil bed. The apparatus is specially adapted to withstand the extreme pressures of deep water applications. In operation, a drill string presses the apparatus of the invention into a soil bed at an uncontrolled rate resulting in a variable penetration rate. The apparatus has a self-contained data acquisition system that measures and records, as a function of time, the force exerted on the sampling apparatus and the depth of penetration as the drill string presses the sampling apparatus into the soil bed.Data is provided that enables the user to determine the static soil characteristics (e.g., shear strength and stress-strain characteristics) and the dynamic loading characteristics of the soil bed. The apparatus captures a sample of the soil for laboratory analysis. The data collected provides information on the quality of the sample and location of defects in the sample which would affect laboratory test results. The apparatus is self-contained and operates independently of surface telemetry. The method of the invention may be performed in less time than known systems and can be advantageously performed from a floating platform, because the apparatus of the invention is self-compensating and not adversely affected by variable sea states. | ||||||
| 62 | Core drilling tool with direct drive | US148676 | 1988-01-25 | US4875531A | 1989-10-24 | Johann Biehl; Alfred Ostertag |
| A core drilling tool with direct drive consisting of an outer pipe that can be connected to a drilling shaft, a core drilling appliance reciprocally mountable in the outer pipe which in turn includes a core barrel that carries a drill bit and an inner pipe mounted in rotatable relation therewith and for reciprocal movement therewith, and a drilling mud driven motor that is integrally coupled to the core drilling appliance and is secured against rotation in the outer pipe and having reaction faces that are put under pressure to produce a downward axial feed force acting on both the core drilling appliance and the motor, plus a capture device for pulling up the motor together with the core drilling appliance. In order to produce a sufficiently great axial feed force of an adjustable size that is essentially independent of the exposure of the core drilling appliance, the motor is connected to the core drilling appliance to form a common movable unit and devices are provided for adjusting the axial feed force. | ||||||
| 63 | Sonic method and apparatus for installing monitor wells for the surveillance and control of earth contamination | US110194 | 1987-10-19 | US4836299A | 1989-06-06 | Albert G. Bodine |
| A well casing of an elastic metal material is placed in concentric relationship with a casing of an inert material such as a suitable plastic. A penetrating cap piece is placed on the bottom end of the metallic casing. The two concentric casings are then driven into the earth in an area to be monitored for contamination, such driving action being achieved by a sonic oscillator which is attached to the top end of the metallic casing. Preferably, the sonic energy is provided at a frequency such as to effect resonant standing wave vibration of the metallic casing. Further, water may be injected down the casing so as to lubricate the earthen structure immediately below the cap to accelerate the penetration of the casing. When the casings have been driven to the desired depth, the metallic casing is withdrawn by lifting up thereon while continuing to apply sonic energy, leaving the casing of inert material in place such that earth samples can be periodically withdrawn from the well thus formed. A core sampling for analysis can also be withdrawn within one of the casings. | ||||||
| 64 | Sediment sampler | US853886 | 1986-04-21 | US4729437A | 1988-03-08 | Michael M. Zapico |
| The sampler disclosed comprises a barrel assembly (21) that is hammered into the ground, from the surface. Hammer-drive-rods are disconnectable from the barrel by manipulation from the surface by means of a left-hand-screw-thread connection (31). The barrel is pulled out of the hole by means of a draw-cable (20). The barrel includes an inner sleeve (16), made of thin aluminum or plastic. This sleeve is cut open to reveal the sample. The sleeve itself is relieved of the hammer blows and other stresses, which are taken entirely by the barrel. | ||||||
| 65 | Method and apparatus for coring rock | US919650 | 1986-10-16 | US4679636A | 1987-07-14 | James L. Ruhle |
| A low-cost retrievable light-weight high-speed thin-kerf reversible electrically-driven core-sampling method and apparatus that is independent of the weight of any drill pipe, drill collars, or any other heavy cylindrical or tubular conduit associated with the coring operation. The flow direction of electric current to the direct-current electric motor of the core-sampling assembly is automatically reversed at frequent intervals so as to cause corresponding reversals in the direction of rotation of its core bit, resulting in the cancellation of any lateral forces on the core bit produced by reactive torque created during the coring operation, since such forces are alternately applied in opposite directions, thus, eliminating any corehole deviation that, otherwise, might occur from the lateral force created by the reactive torque of a down-hole motor that is rotated in just one direction. Geologically-induced lateral forces on the core bit are also minimized because of the light weight and high speed of the reversible electrically-driven core-sampling assembly, which quickly decreases its angle with the vertical, should its trajectory deviate from the vertical. | ||||||
| 66 | Percussion actuated core sampler | US509892 | 1983-06-30 | US4518051A | 1985-05-21 | Steinar Sollie; Arilo A. Andresen |
| The present invention provides a percussion actuated wire line sampler for use in a drill string. The sampler includes a core barrel adapted to be inserted into the drill string and to be freely movable therein. A hydraulic percussion device (16) also insertable and freely movable in the drill string is connected to the core barrel. A downhole mud turbine (20) is provided and is responsive to drilling mud pressure to actuate the percussion device to drive the core barrel out of the end of the drill string into the material to be sampled. | ||||||
| 67 | Apparatus for extracting cores | US117292 | 1980-01-31 | US4279315A | 1981-07-21 | Fritz Tibussek |
| An apparatus for extracting cores comprises an outer tube, an inner tube which contains a core receiving space, and a striking device which comprises a hammer and an anvil for producing a periodic axial movement of the inner tube relative to the outer tube, wherein the inner tube, the striking device and an associated supporting body form a unit which may be moved through the outer tube in the axial direction thereof by means of a withdrawal mechanism, and wherein a part of this unit joined to an element of the striking device for rotational entrainment may be connected to the inner tube. | ||||||
| 68 | Geological sampling device | US28201872 | 1972-08-21 | US3805900A | 1974-04-23 | SAINSBURY C |
| A device to be used during geological exploration for obtaining a specimen of soil lying beneath the surface of the earth. The device is to be dropped from the air, e.g., from a hovering helicopter, and the nose thereof allowed to penetrate the surface of the earth. A sample is collected in the device and the device is retrieved into the hovering helicopter by means of a cable and a winch. The apparatus includes a hollow tubular body having a flange stop-collar approximately midway along the body to limit its penetration into the earth and fins at the tail to aerodynamically guide it during its fall to earth. The front or nose end of the body is provided with spreadable guarding jaws which are closed during impact and which are formed in an arrowhead shape to enhance penetration of the earth. A relatively heavy interior body fits within the hollow body and includes an open front portion to receive a sample. The interior body is releasably retained in a position near the tail of the hollow body by a spring urged pin. After the device is dropped from a helicopter, the pointed guarding jaws of the hollow body penetrate the earth on impact, penetration of the hollow body being continued until the stop collar brings the device to a sudden halt. Inertia of the interior body causes it to be pulled loose from the spring urged pin, the momentum of this body causing it to move through the hollow body and to spread the guarding jaws at the nose end beneath the surface. The interior body continues to move downwardly and passes partly out of the hollow body so that the open front portion thereof penetrates subsurface soil and collects a sample. Retrieval of the cable causes the interior body to withdraw into the hollow body and permits the entire device to be returned to the helicopter.

| 69 | Hollow auger-driver coupling | US3794127D | 1972-06-06 | US3794127A | 1974-02-26 | DAVIS H |
| A coupling for connecting an auger to a driver so as to allow core sampling while the auger is positioned within the drilled hole and connected to the driver. One embodiment of the coupling has a ring positioned outwardly of the adjacent ends of the auger and driver. Arms are mounted to the ring and extend radially inward being bearingly received by the adjacent auger and driver ends. The driver and auger are hollow so as to allow the raising and lowering by cable of a sampling hammer with a sampler. A hollow cap is removably mounted to the top of the auger and has a pair of upstanding members which receive two of the arms of the coupling. A hollow-centered plate is removably mounted to the bottom of the driver and has a pair of depending members which receive the other two arms of the coupling. Another embodiment of the coupling includes a pair of yokes each of which is pivoted to an open centered ring member. The yokes are also coupled, respectively, to the auger and the driver. The yokes extend outwardly of the ring member and are connected through bearings to the ring member.
