Abstract: Embodiments of the present invention generally relate to a method for controlling the torque applied to a tubular connection. In one embodiment, a method of connecting a first threaded tubular to a second threaded tubular supported by a spider on a drilling rig includes engaging the first threaded tubular with the second threaded tubular; making up the connection by rotating the first tubular using a top drive; and controlling unwinding of the first tubular after the connection is made up.

Abstract: Apparatus and methods are provided to prevent an operator from inadvertently dropping a string into a wellbore during assembling and disassembling of tubulars. In one embodiment, an interlock system is used to control the operations of a gripping apparatus connected to the top drive and a spider such that at least one of the top drive or the spider retains the tubular. The interlock system allows the spider to open when the gripping apparatus is supporting a load of the tubular or is in position to support a load of the tubular.

Abstract: Methods and apparatus enable monitoring a hydrocarbon well for water within a flow stream of the well. A water detector includes a light source for emitting into a flow stream infrared light that includes a water absorbent wavelength band. A detector detects attenuation of the water absorbent wavelength band upon the infrared radiation passing through at least a portion of the flow stream. The water detector outputs a presence of water and/or a phase fraction or quantification of water as determined based on the attenuation. Detecting attenuation of a substantially transmissive wavelength band with respect to water simultaneously with detection of the attenuation of the water absorbent wavelength band can enable correction for non-wavelength dependent attenuation.

Abstract: A method for logging a downhole formation in a wellbore. The method comprises drilling a wellbore with a drill bit coupled to a disconnect device (20). The disconnect device is then actuated to detach the drill bit from a portion of a conveyance (40). A logging operation is then performed between two portions of the disconnect device. The disconnect device may then be reattached.

Abstract: Methods and apparatus for reducing the impact of guided (or "tube") waves in permanently installed seismic systems are provided. By utilizing passive acoustic absorbers, the impact of tube waves may be reduced, leading to improved performance of permanently installed seismic systems that are installed onto production tubing when the well is completed.

IPC: H02P6/08

Abstract: An electric submersible pump contains an AC permanent magnet motor having three or more phases A, B, C and has a drive circuit for supplying varying drive signals to all the phases of the motor at the same time. Each drive signal is constituted by a cyclically smoothly varying voltage applied to the corresponding motor phase during driving of the motor. The circuit comprises switches (902, 903) for each motor phase, a control arrangement for turning the switches (902, 903) on and off at a frequency greater than the frequency of the cyclically smoothly varying voltages, and a filter (907, 908) for filtering the output voltages of the switches (902, 903) to produce the cyclically smoothly varying voltages. Such a drive circuit drives all the phases of the motor continuously such that damaging transients will not arise and without requiring the motor emf or drive signals to be sinusoidal.

Abstract: A downhole electric motor for a submersible pump has at least three phases and comprises a permanent magnet rotor and a stator bearing phase windings (A, B and C) in slots in the stator. Each phase winding (A, B, C) incorporates a coil extending through a respective pair of adjacent stator slots and surrounds a respective portion of the stator between the slots. Furthermore adjacent coils of each pair of phase windings (A, B, C) extend through opposite parts of a respective one of the slots, so that these coils extend alongside one another in the slot, either being separated by a gap through which cooling fluid may be pumped to cool the coils, or being separated by a thermally conductive projection, with which the coils are in thermal contact, extending at least part of the way across the slot. Such a winding arrangement is advantageous in ensuring that the motor has a long life.

Abstract: A method of pumping wellbore fluid, comprising the steps of: installing an electric submersible pump in a wellbore; and operating the pump at more than 4,500 rpm to pump the wellbore fluid. Pumping in this manner provides a number of advantages in use in that the required high-speed motor and pump is shorter for a given power than existing arrangements, and provides increased reliability due to reduced complexity. A much shorter motor/pump combination also allows such equipment to be used in deviated boreholes with a reduction in damage due to mishandling and bending, as well as facilitating assembly and testing in the manufacturer's plant.
