A new pump design, a “smart” variable speed drive (VSD), and power monitoring capabilities now available to the oil field are designed to enhance the operating range and reliability of electrical submersible pumping (ESP) systems and to reduce operating expenses associated with ESPs.
The Centrilift FlexPump ESP design covers a wide operating range and delivers high efficiencies in challenging downhole applications, including wells producing gas-laden or solids-laden fluids. Patent-pending thrust balancing technology in the pump stage diffuser expands the FlexPump operating range by acting as a relief valve for high-pressure applications—forcing the impeller into downthrust at higher flow rates to decrease upthrust wear.
The Centrilift Electrospeed Advantage next-generation VSD features a smart software suite to constantly monitor the downhole ESP system and automatically make adjustments to its operating parameters to improve uptime, efficiency, and reliability. The new design also includes seamless integration with Vision monitoring and automation services as well as downhole sensors.
The Centrilift PowerMonitor module further enhances ESP system efficiency to lower producers’ power costs and maximize system run life. The module is installed on the input to the VSD and provides information on the quantity and quality of the power supply. The PowerMonitor device achieves better than 99% accuracy for measurements such as line voltage, phase voltage/current, and harmonics. The data are then used to optimize ESP system operating parameters to lower power costs.

New Ultralow Emission BurnerThe new XPO NOx burner offers optimal fuel usage and reliable ultralow emissions.
It produces single-digit NOx at minimal excess air without the complexities of flue gas recirculation, exotic materials, or restrictive metal fiber, while providing as high as a 6:1 turndown ratio, the maker notes. Its expanded range now offers five sizes, with capacities of as much as 8 Mbtu.
The indirect burner is designed for simple installation and retrofits easily into existing applications such as water bath heaters, thermal oil heaters, direct contact water heaters, solution heating/tanks, and snow melters.
The burner is available with your choice of parallel positioning control systems—Maxon or Honeywell Smart FARC—to enhance the built-in efficiency of XPO and provide the maximum in safety, reduced maintenance, and environmental assurance.

New Meter Prover InterfaceHere’s newly released version 2.07 of the liquid and gas flow computer for the Rockwell Automation ControlLogix platform (MVI56-AFC).
In oil applications, crude is extracted and transported through pipelines that often run hundreds of miles through varying climates, temperatures, and altitudes. As these elements vary, so do the properties of the petroleum, necessitating flow computers to validate the precise volume of product at designated points along the pipeline. Precise flow calculations require accurate data from properly calibrated flowmeters. Meter provers help validate proper flow meter operation, the firm points out.
This flow computer calculates a meter factor based on constants and variables affecting flow rates, accumulated volumes, and accumulated mass of the liquid petroleum product flowing through a prover with known volume. With the new meter proving feature, the module is now able to communicate meter prover test results directly to the control processor and SCADA control system. Operation of the prover interface feature can be completely automated, can be performed manually, can be scheduled, or can be triggered by events or operator intervention.

New Unit For Intrinsic Safety Fieldbus InstallationsThe new dynamic arc recognition and termination (DART) system is a dynamic power supply and control system for intrinsically safe fieldbus installations that helps increase the power available to field devices in explosion hazardous areas, while maintaining intrinsically safe energy levels.
The system supplies enough power to support nearly as many devices as is typically supplied in nonhazardous areas and can also power field instruments that previously required more power than intrinsically safe solutions could offer, the company says.
During normal operation, a DART power supply feeds full nominal power of 8-50 w—exponentially more power than the approximately 2 w that is normally permissible in intrinsic safety environments. Should a fault occur, the potential spark remains nonincendive, and DART detects the resulting change in current and immediately switches off the power supply.
