摘要： A jet drill coupled to a distal end of a flexible jet lance is lowered into a well casing and advanced through a curved passage formed in a deflection shoe oriented to direct the jet drill through an orifice milled in the well casing. The jet drill is actuated with a pressurized fluid produced by a pump on the surface that is conveyed through a high pressure hose that runs through the flexible jet lance. Force transmitted through a thrust liner of the jet lance advances the jet drill while the lateral bore is being drilled. The thrust liner comprises helical coils of steel wire providing a high elastic modulus and buckling resistance, even while passing through the curved passage. Tension cables in the jet lance maintain tension on the thrust liner and enable the assembly to be pulled from the lateral bore and well.

摘要： A drilling system has a drill string that is made up of tubular segments of coiled tubing joined together by connectors. The connectors can be selectively changed between locked and unlocked configurations. When in the unlocked configuration adjacent tubular segments rotate with respect to one another, and when in the locked configuration the tubular segments are rotationally affixed. The connectors include clutch members coupled to each tubular segment, that axially slide into a slot formed in an adjacent tubular segment to rotationally lock the adjacent segments. A Kelly bushing and rotary table rotate the drill string; and an injector head is used to insert the drill string through the Kelly bushing and rotary table and into a wellbore. While the drill string is inserted through the bushing and table, the connectors are set into the locked configuration so that all tubular segments from the rotary table downward are rotationally affixed.

摘要： A technique facilitates transmission of electric signals across well components which move relative to each other in a wellbore environment. The well components are movably, e.g. rotatably, coupled to each other via one or more conductive bearings. Each conductive bearing has a conductive rolling element which enables relative movement, e.g. rotation, between the well components while simultaneously facilitating transmission of electric signals through the bearing. Portions of the bearing are coupled to each of the well components, and those bearing portions may be connected with electric leads to enable flow of electric signals through the bearing during operation of the system downhole.
