For instance, a commercially accessible ESP (similar to one of the REDA™ ESPs marketed by Schlumberger Limited, Houston, Tex.) could also be employed to pump fluid(s). As to the ESP 210, it's shown as together with one or more cables 211, a pump 212, gasoline dealing with options 213, a pump intake 214, a motor 215, one or more sensors 216 (e.g., temperature, stress, current leakage, vibration, and so forth.) and optionally a protector 217. The motor 215 could be a submersible electric motor that's operatively coupled to the pump 212 to drive the pump 212 for motion of fluid (e.g., low voltage armored power cable to pump fluid). For example, the UNICONN™ motor controller can interface with the PHOENIX™ monitoring system, for instance, to entry strain, temperature and vibration knowledge and numerous protection parameters in addition to to offer direct present power to downhole sensors. The UNICONN™ motor controller can embody management functionality for VSD models resembling goal speed, minimal and maximum speed and base speed (voltage divided by frequency); three leap frequencies and bandwidths; volts per hertz pattern and start-up boost; ability to start out an ESP whereas the motor is spinning; acceleration and deceleration charges, together with begin to minimum speed and minimum to target pace to keep up constant pressure/load (e.g., from about 0.01 Hz/10,000 s to about 1 Hz/s); cease mode with PWM service frequency; base speed voltage selection; rocking begin frequency, cycle and sample management; stall safety with computerized pace reduction; changing motor rotation direction without stopping; velocity force; speed follower mode; frequency management to keep up constant pace, pressure or load; current unbalance; voltage unbalance; overvoltage and undervoltage; ESP backspin; and leg-ground.

As an example, an atmosphere might have its pressure and/or temperature elevated, for instance, through use of tools, techniques, etc. For instance, a SAGD operation could elevate temperature of an setting (e.g., by a hundred degrees C. or extra). As such, lead (Pb) can creep at ambient temperature (e.g., 25 degrees C.) when pressure of several megapascals (MPa) is utilized. A so-called HPHT atmosphere might embrace pressures up to about 138 MPa (e.g., about 20,000 psi) and temperatures up to about 205 degrees C. (e.g., about 400 degrees F.), a so-referred to as ultra-HPHT surroundings may embody pressures up to about 241 MPa (e.g., about 35,000 psi) and temperatures as much as about 260 degrees C. (e.g., about 500 degrees F.) and a so-known as HPHT-hc surroundings may embody pressures greater than about 241 MPa (e.g., about 35,000 psi) and temperatures greater than about 260 levels C. (e.g., about 500 levels F.). Where gear is to endure in an environment over a considerable time period, uncertainty may arise in a number of factors that could affect integrity or anticipated lifetime of the tools. For instance, particulate matter in an surroundings could also be abrasive or otherwise damaging to gear.

FIG. 2 reveals an example of a system 200 that features an ESP 210 for instance of gear that could be placed in a geologic setting. In the instance of FIG. 2, the system 200 includes a network 201, a properly 203 disposed in a geologic setting, a energy provide 205, the ESP 210, a controller 230, a motor controller 250 and a variable speed drive (VSD) unit 270. The ability supply 205 may obtain energy from a power grid, an onsite generator (e.g., natural gas driven turbine), or other source. In the example of FIG. 2, the VSD unit 270 could also be a low voltage drive (LVD) unit, a medium voltage drive (MVD) unit or other type of unit (e.g., a excessive voltage drive, which may provide a voltage in excess of about 4.Sixteen kV). For instance, the VSD unit 270 might obtain power with a voltage of about 4.Sixteen kV and management a motor as a load with a voltage from about zero V to about 4.Sixteen kV.

For a LVD, a VSD unit can embody a step-up transformer, management circuitry and a step-up transformer while, for a MVD, a VSD unit can embody an built-in transformer and management circuitry. As an example, the UNICONN™ motor controller can carry out some control and data acquisition tasks for ESPs, surface pumps or different monitored wells. Further, the controller 230 may embrace features of a motor controller and optionally supplant the motor controller 250. For instance, the controller 230 could embrace the UNICONN™ motor controller 282 marketed by Schlumberger Limited (Houston, Tex.). In the instance of FIG. 2, the controller 230 may access a number of of the PIPESIM™ framework 284, the ECLIPSE™ framework 286 marketed by Schlumberger Limited (Houston, Tex.) and the PETREL™ framework 288 marketed by Schlumberger Limited (Houston, Tex.) (e.g., and optionally the OCEAN™ framework marketed by Schlumberger Limited (Houston, Tex.)). In the instance of FIG. 9, the armor 780 contains edges 782 and 784 the place the sting 782 could also be an exposed edge and where the sting 784 could also be a covered edge the place the armoring course of spirals the armor 780 with overlap. In the example of FIG. 2, the motor controller 250 consists of various options to handle, for instance, backspin of an ESP, sanding of an ESP, flux of an ESP and gas lock of an ESP.
