    Abstract: Systems and methods for drilling a wellbore include delivering electrical energy to a downhole end of the wellbore. A tapered drill string, with larger drill pipes connected in an up-hole portion with a turbine and an electrical generator and a smaller drill pipes coupled in downhole portion may be used to deliver the electrical power. A turbine and generator may be sufficiently sized to harvest the necessary hydraulic energy and safely operated in a subterranean environment. A lower portion system carried by the downhole portion of the drill string is electrically coupled to the generator through the downhole portion of the drill string to utilize the electric power provided by the electrical generator.

    Abstract: Methods, devices and systems are disclosed for magnetically ranging while drilling with a coiled tubing unit or drill pipe by way of a an electrically conducive but environmentally electrically insulated wire installed through a coiled tubing spool or drill pipe complete with electrically insulative subs in the coiled tubing bottom hole assembly or drill pipe. The method and systems allow for the injection of excitation current into the formation by way of selectively electrifying various drill stem components, thereby facilitating current collection on a target tubular which radially emanates a magnetic field about the target well tubular(s). The method and devices allow for the construction of complex downhole current injection configurations which allow for modification of the bottom hole assembly to maximize target well signal generation in the presence of adverse environmental conditions.

    Abstract: A drilling system includes a drill string extendable into a borehole from a drilling platform and conveying a drilling fluid to a drill bit arranged at a distal end of the drill string, an annulus defined between the drill string and an inner wall of the borehole and in which spent drilling fluid ejected from the drill bit flows back to the drilling platform, and a plurality of nozzle assemblies installed on the drill string, each nozzle assembly providing a fluid flow path between an interior of the drill string and the annulus. Each nozzle assembly is transitionable between a closed state, where the drilling fluid within the interior is prevented from passing through the fluid flow path, and an open state, where the drilling fluid traverses the fluid flow path and is discharged into the annulus to combine with the spent fluid.

    Abstract: The present invention is directed to a method of cleaning and inspection of drilling mud carrying flow lines, each flow line having an inner surface. The method includes affixing a fitting to the flow line, the fitting having a main flow channel and a branch flow channel extending at an angle from said main flow channel. A first end portion of the fitting can have an attachment that enables connection of the fitting to the flow line at one flow line end portion. A second end portion of the fitting can have one or more doors that can be moved between opened and closed positions, the door or doors providing an opening that is not closed when the doors are in the closed position. A suction line can be connected to the branch flow channel. A cleaning tool can be guided first into the fitting and then into the flow line using a fluid carrying cable. The cleaning tool and jetting fluid can be used to clean drilling mud and debris from the inner surface of the flow line. The jetting fluid can be removed via the branch flow channel using the suction line. The cable can extend through the door opening or openings when the door or doors are in the closed position. A camera can be guided into the flow line using a camera cable wherein the camera cable extends through the door opening or openings. The cleaning tool is preferably too small to fit through the door opening.
