  • Patent number: 9702210
    Abstract: A method and apparatus are disclosed for drilling a wellbore using a concentric dual drill string. Multiple individually selectively isolable crossover ports intervaled may be provided along the length of the drill string thereby facilitating pumping a well control fluid within a wellbore annulus without the need to run-in or trip-out the drill string. Multiple one way check valves may be included at various points within an inner pipe of the dual drill string to minimize settling of particulate matter during long periods of non-circulation. In an offshore arrangement, the drill string may be used without a marine riser. A rotating control device is provided, and a hydraulic power unit is located at the seafloor for controlling and lubricating the rotating control device. A pump may be located at the seafloor for managing wellbore annulus pressure via the rotating control device.

  • Patent number: 9404482
    Abstract: An operational control device is disclosed for a positive-displacement pump having a motor, means for actuating the motor, state sensor means for detecting an actual operating parameter (e.g., pressure) of the pump, and operating mode means for controlling an operating mode of the pump. A first actuating mode of the operating mode means is set by the actuating means below a first operating-parameter threshold value (P1). This mode brings about a constantly rising pump pressure in the direction of an operating-parameter setpoint value (Pset) in a variable manner, which is dependent on a detected change in the operating parameter over a predefined time interval. A second actuating mode is set as normal operation to the operating-parameter setpoint value by the actuating means above the first operating-parameter threshold value. P1 is fixed or is calculated as a fraction of the operating-parameter setpoint value and/or a pump parameter correlated therewith.

  • Patent number: 8904703
    Abstract: Apparatus and method for boring into the earth near a Kudzu vine root system to apply herbicidal helium gas to the roots and eradicate the Kudzu vine. The technique uses a perforated tube with a drill bit that protrudes from one end of the tube to bore into the earth near the vine roots. Boring is stopped when all of the tube perforations are below the earth's surface. About 0.5 cubic meters of helium gas are applied to flow through the tube enabling the helium gas to flow out through the tube perforations and attack the Kudzu vine through the vine's root system.

    Abstract: A method of drilling a wellbore with a downhole tool having a cam piston, and a rotary piston includes providing a first flow of fluid to the downhole tool. The first flow of fluid causes the cam piston to move axially downward, thereby rotating a rotary valve of the rotary piston, which in turn places the downhole tool in a compressed position to activate a secondary tool. Next the formation may be drilled with the downhole tool in a compressed position. A second flow of fluid may be provided to the downhole tool to move the cam piston axially downward thereby rotating the rotary valve and deactivating the secondary tool.

  • Publication number: 20040140129
    Abstract: A method and system of drilling straight directional and multilateral wells utilizing hydraulic frictional controlled drilling, by providing concentric casing strings to define a plurality of annuli therebetween; injecting fluid down some of the annuli; returning the fluid up at least one annulus so that the return flow creates adequate hydraulic friction within the return annulus to control the return flow within the well. The hydraulic friction should be minimized on the injection side to require less hydraulic horsepower and be maximized on the return side to create the desired subsurface friction to control the well.

  • Publication number: 20040084214
    Abstract: A system for controlling drilling mud density at a location either at the seabed (or just above the seabed) or alternatively below the seabed of wells in offshore and land-based drilling applications is disclosed. The present invention combines a base fluid of lesser/greater density than the drilling fluid required at the drill bit to drill the well to produce a combination return mud in the riser. By combining the appropriate quantities of drilling mud with a light fluid, a riser mud density at or near the density of seawater may be achieved to facilitate transporting the return mud to the surface. Alternatively, by injecting the appropriate quantities of heavy fluid into a light return mud, the column of return mud may be sufficiently weighted to protect the wellhead. At the surface, the combination return mud is passed through a treatment system to cleanse the mud of drill cuttings and to separate the drilling fluid from the base fluid.

  • Publication number: 20030141111
    Abstract: A method of drilling and lining a bore in an earth formation comprises providing a tubular outer elongate member and an inner elongate member located within the outer member. At least one of the members is spoolable. A drill bit is mounted to one of the members and a bore is drilled by advancing the drill bit through the earth formation and advancing the members through the bore.

  • Patent number: 6405812
    Abstract: A drilling tool for drilling bore holes into the ground and for removing the drilled material using an air-lifting process. The drilling tool has a drilling head equipped at its lower surface with curing elements, whose upper surface is connected to hollow drilling rods having an inner conveying channel and from whose lower surface boring material mixed with a rinsing liquid is removed via the conveying channel. At the lower surface of the drilling tool head, inside a radial channel connected to the conveying channel, a cross-flow of the rinsing liquid, flowing radially inwards and having a high flow velocity, is produced for the purpose of carrying along the boring material.

  • Patent number: 6371223
    Abstract: A drill head for an apparatus for directional boring includes a bit having a cutting portion for use in steering, such as a gage tower mounted with carbide studs, suitable for cutting both hard and soft rock, a holder for a device for detecting angular orientation of the bit, and a pneumatic hammer connected head to tail with the bit at the front end. The valve in the hammer initiates reciprocation of the hammer in response to rearward movement of the bit, such as in response to a pushing force exerted by the drill string. The drill string components are preferably keyed to one another so that the orientation of the cutting portion of the bit used for steering is automatically matched to the position of the sonde. The sonde may project laterally so that its mass centroid is on the opposite side of the cutting portion of the bit used for steering to provide better cutting action. Such a drill head is suited for drilling in soil, soft rock and hard rock conditions.

  • Patent number: 6367566
    Abstract: The system and method of the present invention permits control of down hole fluid pressures during under balanced drilling, tripping of the drill string, and well completion to substantially avoid “killing” of the well and thereby damaging the producing formations in the well bore. The system and method utilizes separate and interconnected fluid pathways for introducing a downwardly flowing hydrodynamic control fluid through one fluid pathway and for removing through the other fluid pathway a commingled fluid formed by mixing of the hydrodynamic control fluid and the well bore fluids flowing upwardly in the well bore.
