Wellsite Intelligence with the Electrical Submersible Pump (ESP) Solution

Intelligent ESP RTU

The intelligent controller provides 24 hour wellsite control and optimization. The intelligence is distributed to the wells. The controller interacts with downhole sensors and surface instruments to accurately measure conditions and control the well operation. The controller can operate in stand-alone mode and control the wells based on the parameters that are entered at the site. The controller comes programmed with templates that allow it to control the startup and speed of the ESP well based on the input received from the downhole sensors, motor controller and other equipment at the well site. Weatherford's intelligent RTU has built-in interfaces for the Vortex, Keltronics, CTI and GCS motor controllers available in the market today.

Vector Flux Drive (VFD)

The VFD uses data to adjust the speed of the ESP. It uses a startup control strategy to ramp well on production, consistent with other constraints by using a VFD or surface choke (backpressure) which eliminating hard starts that create excess stress on the pump and motor. By using a VFD, the operator has the ability to set the parameters so that the pump will react to changes in the well. This means that the pump will continue to operate efficiently. The VFD can be used as part of an Intelligent Wellsite ESP installation, in conjunction with the Software from the Intelligent Desktop ESP system or as a stand alone control system.
