With Above-ground Means For Handling Drilling Fluid Or Cutting Patents (Class 175/207)
  • Patent number: 9664027
    Abstract: Systems, apparatus and methods are described for purposes of initiating a response to detection of an adverse operational condition involving a system including a drill rig and an inground tool. The response can be based on an uphole sensed parameter in combination with a downhole sensed parameter. The adverse operational condition can involve cross-bore detection, frac-out detection, excessive downhole pressure, a plugged jet indication and drill string key-holing detection. A communication system includes an inground communication link that allows bidirectional communication between a walkover detector and the drill rig via the inground tool. Monitoring of inground tool depth and/or lateral movement can be performed using techniques that approach integrated values. Bit force based auto-carving is described in the context of an automated procedure.

  • Patent number: 8496063
    Abstract: A method and device for recovering drilling fluid used in connection with the provision of a subsea well, in which the drilling fluid is circulated from a vessel on a sea surface via a drill string and out through a drill bit into an annulus which is defined by a borehole and the drill string. The device includes a filtering device which is connected, in respect of fluid, to an annulus and which is arranged to contain drill cuttings and drilling fluid. A fluid line extends from a portion of the filtering device to the vessel, the fluid line being arranged to carry drilling fluid which has been separated from the drill cuttings back to the vessel.

  • Patent number: 8469116
    Abstract: Techniques for controlling drilling fluid cleaning apparatus that reclaim lost circulation material from spent drilling fluid are disclosed. In one embodiment, a system includes a tank, a density separation device, and a fluid density control system. The tank holds spent drilling fluid containing drilling fluid, lost circulation material, coarse solids and fine solids. The density separation device is coupled to an outlet of the tank. The density separation device provides an overflow stream and an underflow stream. The overflow stream contains less dense material than the underflow stream. The fluid density control system is configured to adjust the density of the spent drilling fluid provided to the density separation device by recirculating a portion of the underflow stream into the tank.

  • Patent number: 8453758
    Abstract: Systems and methods for lifting drilling fluid from a well bore in a subsea formation are disclosed. Some system embodiments include a drill string suspended within a drilling riser to form the well bore, and a drilling fluid source for supplying drilling fluid through the drill string during drilling. A diverter is coupled between the drilling riser and a return line, while a power riser coupled to the return line at an interface. A lift fluid source supplies lift fluid through the power riser into the return line. The lift fluid is intermittently injected from the power riser through the interface into the return line to form one or more slugs of lift fluid positioned between slugs of drilling fluid, such that the combined density of lift fluid and drilling fluid in the return line is less than the density of the drilling fluid alone.

  • Patent number: 8322464
    Abstract: A system for continuously feeding drill cuttings extracted from a cutting source into a liquid. The system has an open bottomed vacuum hood, means for positioning the open bottom of the vacuum hood in a liquid, means for creating a vacuum in the vacuum hood, a conduit for transporting the drill cuttings from the cutting source to the open bottomed vacuum hood, from which vacuum hood the drill cuttings fall, under the influence of gravity, through the open bottom of the vacuum hood and are thereby deposited into said liquid. Embodiments include means for removing and recovering residual drilling fluids extracted with the drill cuttings, reducing the size of the drill cuttings so they may be injected into a porous earth formation, relieving choke points and blockages.

  • Publication number: 20120292020
    Abstract: A vortex-controlled variable flow resistance device ideal for use in a backpressure tool for advancing drill string in extended reach downhole operations. The characteristics of the pressure waves generated by the device are controlled by the growth and decay of vortices in the vortex chamber(s) of a flow path. The flow path includes a switch, such as a bi-stable fluidic switch, for reversing the direction of the flow in the vortex chamber. The flow path may include multiple vortex chambers, and the device may include multiple flow paths. A hardened insert in the outlet of the vortex chamber resists erosion. This device generates backpressures of short duration and slower frequencies approaching the resonant frequency of the drill string, which maximizes axial motion in the drill sting and weight on the bit. Additionally, fluid pulses produced by the tool enhance debris removal ahead of the bit.
