  • Patent number: 8857537
    Abstract: A method and apparatus for down-the-hole drilling. The drilling is carried out by a drilling device including a casing and a drilling unit. The drilling head includes a first drill for drilling a center hole, a second drill for reaming the center hole and a flushing flow arrangement including a first flusher for leading a flushing medium onto a drilling surface and a second flusher for returning of the flushing medium and drilling waste inside the casing. The first drill is removably coupled with the second drill to enable removal thereof from the hole. The casing is arranged to be drawn into a hole to be drilled by the drilling unit. The flushing medium is brought onto the drilling surface and returned therefrom by axially directed flow arrangements disposed in a cross-section view on an outer periphery of the first drill and/or in an inner periphery of the second drill.

  • Patent number: 8820007
    Abstract: A post sleeve installation assembly includes: an elastomeric sleeve core shaped to form a post sleeve when positioned in uncured concrete, a removable stiffener inside the core, an aperture extending lengthwise in the stiffener, a locking element positioned within the core, and an assembly plate coupled to the stiffener. The assembly plate clamps to a prefabricated sleeve element, with the core and stiffener positioned within a post cavity of the sleeve element. an installation stake is positioned in the aperture and prevented from sliding upwards by the locking element. A release point on the assembly plate permits an operator to release the locking element for removal of the stake. To install a post sleeve, the operator positions the installation assembly, clamped to a prefabricated sleeve element, in a post hole with the stake resting on the bottom, then fills the hole with concrete, manipulating the stake to position the assembly.

  • Patent number: 8434561
    Abstract: A method of drilling and completing a well can include drilling a section of a wellbore, positioning a perforated shroud in the section of the wellbore, securing the perforated shroud by setting a hanger, and isolating the section of the wellbore from a remainder of the wellbore vertically above the section of the wellbore. The drilling, positioning, securing and isolating steps can be performed while the section of the wellbore is not exposed to a liquid column extending to a surface location. The drilling, positioning, securing and isolating steps can be performed in a single trip of a drill string into the wellbore.

  • Patent number: 8347983
    Abstract: A Drill-To-The-Limit (DTTL) drilling method variant to Managed Pressured Drilling (MPD) applies constant surface backpressure, whether the mud is circulating (choke valve open) or not (choke valve closed). Because of the constant application of surface backpressure, the DTTL method can use lighter mud weight that still has the cutting carrying ability to keep the borehole clean. The DTTL method identifies the weakest component of the pressure containment system, such as the fracture pressure of the formation or the casing shoe leak off test (LOT). With a higher pressure rated RCD, such as 5,000 psi (34,474 kPa) dynamic or working pressure and 10,000 psi (68,948 kPa) static pressure, the limitation will generally be the facture pressure of the formation or the LOT. In the DTTL method, since surface backpressure is constantly applied, the pore pressure limitation of the conventional drilling window can be disregarded in developing the fluid and drilling programs.

  • Patent number: 6102119
    Abstract: A method is disclosed for installing a tubular member, having an upper end and a closed lower end, axially into and through an over-pressured region of the earth by using a mandrel to drive the tubular member from near the bottom, which results in a significant section of the tubular member being pulled through the over-pressured region. In another embodiment, a filler material is inserted into at least a portion of the tubular member, and the tubular member is driven from the upper end, with the filler material assisting the progression of the tubular member through the over-pressured region.

  • Patent number: 5549170
    Abstract: A drill string is advanced into the ground by inducing vibrations in the drill string at a resonant frequency. The drill string has an opening at a downhole end leading to a hollow interior. As drilling progresses, a core enters the hollow interior. A casing is driven around the drill string to seal the borehole. Sonic advancing of the drill string minimizes waste materials and can be operated without a circulating fluid.

  • Patent number: 5281775
    Abstract: A vibrating hole forming device for seismic exploration in which a vertically elongated mounting pipe with attached rack gear is powered vertically by a hydraulically driven pinion gear which will mechanically push the pipe downwardly into the earth's surface. A vibrating mechanism imparts vibration to the downward force exerted by the pinion gear and rack gear. Vibration is imparted to the pipe automatically when hydraulic pressure required to operate the pinion gear reaches a predetermined pressure such as when the point on the lower end of the pipe encounters a predetermined resistance to further downward movement. This enables a lightweight unit to impart a constant downward force and a vibration force when needed to enable the device to penetrate through sands or extremely dense subsurface terrain thereby eliminating the necessity of providing a heavy weight vehicle such as is required when conventional hole forming devices are used on which the device is mounted.

  • Patent number: 5146998
    Abstract: A system and method for implanting an underground device. The system includes a hollow body for containing said underground device and a drive cone adapted to penetrate the ground. The drive cone is removably attached to the hollow body so that once the system is driven into the ground to a desired depth, the hollow body may be pulled upward slightly to cause the drive cone to be removed. This permits underground fluids to enter the hollow body and the underground device. The system provides a durable and inexpensive method for sampling fluids from a desired depth without requiring the drilling of a well.
