  • Publication number: 20180171788
    Abstract: Methods and systems for measuring neutron sigma of downhole reservoir as a function of time for a predetermined testing volume are disclosed. The methods and systems of the present invention analyze the testing volume while maintaining the formation in the testing volume in an unchanged and undamaged state and while dynamically flowing fluids in and out of the testing volume. The systems and methods of the present invention are especially important in determining petrophysical information about the reservoir as well as the in-situ effect of substances on enhanced oil recovery.

  • Publication number: 20180142541
    Abstract: Permanent magnet motor (PMM) powered artificial lift apparatus and methods of practicing the same. The PMM artificial lift apparatus provides a method for the use of permanent magnet motors below perforations, and which may also be used in conditions of low flow rate or extremely high viscosity above perforations without any active cooling schemes.

  • Publication number: 20070293087
    Abstract: An electrical connector assembly for a cable having a plurality of insulated conductors comprises a body having a respective recess for receiving a terminating pin each of the conductors. A respective spigot sealingly engages within each of the recesses and has a passage for receiving an associated one of the terminating pins. Furthermore a seal is associated with each of the spigots for sealing the spigot relative to the associated terminating pin. The provision of a separate spigot for each of the conductors and for sealing engagement within a respective recess in the body enables the spigots to be sealingly fitted to the conductors prior to each spigot being introduced into its recess and sealingly engaged therein. This provides improved insulation of the conductor and increased creepage distance between the mating electrical parts and the outer surface of the housing of the assembly.

  • Publication number: 20070096571
    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(2206) in the stator. Each phase winding A, B, C incorporates a coil extending through a respective pair of adjacent stator slots (2206) and surrounds a respective portion of the stator between the slots (2206). Furthermore adjacent coils of each pair of phase windings A, B, C extend through opposite parts of a respective one of the slots (2206), 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 (3110), 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.

  • Publication number: 20070071612
    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.

  • Publication number: 20060175064
    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.

  • Patent number: 5367911
    Abstract: A device (30) for sensing fluid behavior, e.g. flow, in a conduit (34) such as downhole in a well, comprises a tool (36) having two or more spaced sensors (38,40) for interacting with a medium within the conduit to produce data signals. The sensor data signals may be compared to determine movement of the medium within the conduit and about the device. The device is particularly suited for determining movement of multi-phase fluid.
