  • Patent number: 9284811
    Abstract: A rotating flow head has a lubricated bearing pack for isolating bearing elements from wellbore fluids under pressure. The bearing pack, having a rotating cylindrical sleeve, bearing elements and two seal assemblies, is secured within an assembly bore of a stationary housing by a retainer plate accepting a plurality of lag bolts circumferentially spaced around a top portion of the stationary housing. Each of the seal assemblies have at least one sealing element having a body, an annular cavity, an inner sealing surface, and a flange that distends radially outwardly when axially compressed. A loading ring fit to the annular cavity urges the inner sealing surface radially inwardly to sealingly engage the rotating cylindrical sleeve. The inner sealing surface further comprises a first and second sealing surface and a debris channel therebetween.

  • Patent number: 8988030
    Abstract: This disclosure is drawn to methods, systems, devices and/or apparatus related to power control in applications over long cables. Specifically, the disclosed methods, systems, devices and/or apparatus relate to power control that considers the maximum power available at the end of a long cable (or from a battery) to a load over a broad range of load conditions. Some example systems may include a power supply located at the Earth's surface and a power converter coupled to the power supply via a cable having a first end coupled to the power supply and a second end coupled to the power converter. Some example power converters may be configured to measure the power being consumed by the electrical load in the well, and adjust operating parameter(s) of the electrical load based, at least in part, on the maximum power available at the second end of the cable.

  • Patent number: 8047306
    Abstract: A low speed alternating current motor having motor shaft speeds of about 300 is provided, and such motor has application in numerous industries and devices, such as, for example, in top drive drilling systems. Because of the low shaft speed, mechanical speed reduction equipment may not be necessary. In addition, the motor shaft may be hollow to facilitate the flow of fluid, such as, for example, drilling mud.

  • Publication number: 20110224859
    Abstract: A method for using a mining vehicle, arrangement in a mine, rock drilling rig, and mining vehicle. Tasks according to a work cycle are performed at work sites with a mining work device in a mining vehicle. At the work site, the vehicle is connected to an external electrical network. An energy storage of the vehicle is charged during the work cycle defined by a excavation plan, when the vehicle is at a work site. After the work cycle is done, electricity obtained from the energy storage is used in a transfer drive.

  • Publication number: 20110180326
    Abstract: An apparatus for cutting a wellbore includes a motor with a stator and a rotor. The rotor includes an output shaft connected to a cutting structure to drive the cutting structure in use. The stator and rotor are spaced radially outwardly of the axis of the rotor such that at least one of the stator and the rotor has an access bore that extends through the motor to a position adjacent the cutting structure and through which a further object can pass without obstruction from the stator and rotor. The further object includes a further cutting structure. The motor workings are radially outward of the output shaft and the further cutting structure so as not to obstruct passage of the further cutting structure toward the cutting structure, such that the motor workings do not require drilling or removal to allow the further cutting structure access to the cutting structure.

    Abstract: A well drilling head comprises a housing and a bearing assembly. The housing has a sidewall structure defining a central bore. The bearing assembly includes an outer barrel, an inner barrel, bearing units and a preload force exerting member. The outer barrel has a central bore and the inner barrel is removably seated within the housing central bore. The bearing units are coupled between the barrels for providing concentric alignment of the barrels and allowing rotation therebetween. A first one of the bearing units is configured for carrying loads exerted radially between the barrels and a second one of the bearing units is configured for carrying loads exerted longitudinally between the barrels. The preload force exerting member maintains force on the longitudinal load carrying bearing unit and said barrels thereby preloading the longitudinal load carrying bearing unit.
