Topside Multiphase Meter
(Formerly MPM High Performance Flowmeters)
The topside multiphase meter is intended for production monitoring, well testing and allocation metering purposes. It can be supplied as a Multiphase meter, a Wetgas meter, or as a combined Wetgas and Multiphase meter.
Topside multiphase meter are installed permanently at onshore and offshore sites. They measure continuously and real-time the production from any well. The measurements help increasing the knowledge of the reservoar and how wells behave, and how well artificial lift and other production stimuli systems work. MPM meters can give significant contributions to optimizing production, recovery and revenue. It will also help reducing the size and complexity of metering systems. They can be used to increase capacity of, and in some cases instead of, test separators.
The topside multiphase meter can be equipped with all of the special features. The topside multiphase meter is built with all parts in one unit with minimum need for final assembly on site. The electronics are designed and built to survive in severe and violent conditions and the transmitters are fixed to the sensor body.
• Dual Mode (multiphase & wetgas) - Meter works equally well over full GVF range and for different .. flow conditions. At slug .. flow it switches automatically between modes.
• Unparalleled Accuracy and Sensitivity - Accuracy demonstrated during quali.. cation testing approaching the level of single phase metering, on accumulated (allocation) basis.
• Remote Access and Operation - Internet access to Graphical User Interface and full functionality via web-interface in MPM .. flow computer at site.
• Easy Field Configuration - Meter is factory calibrated. The user friendly field configuration can even be fully completed at factory prior to delivery.
• Water Salinity Measurement - Eliminates the need for water sampling. Automatic update of water configuration data and elimination of potential errors caused by incorrect input data.
• Self Diagnostics Functionality - Meter includes a large series of self diagnostics features. These are based on raw data analysis, redundancy and statistical analyses.
• In-Situ Verification - Responding to the obvious question: Are meter readings correct? Covers sensor parts as well as configuration data.
• HP/HT Qualified - Mechanical integrity verified for pressures of up to 1000 bar (15,000 psi) and temperatures of up to 250°C (480°F). Statement of Compliance issued by DNV.
One Meter Covers It All
The topside multiphase meter performs measurements over the full Gas Volume Fraction (GVF) range, from 0 to 100%. For GVF's up to 90-95% GVF, the Meter typical operates in Multiphase mode. For GVF's above 95%, the Meters Wetgas mode should be used. The hardware is identical; however, the metrology applied and the associated software is different for the two modes.
For all GVF's, the topside multiphase meter covers the full range of watercuts, from 0 to 100%. One of the Meters really unique properties is the ability to measure the watercut equally well at high watercuts (water continuous flow) and lower watercuts (oil continuous). As a consequence, the MPM Meter performs reliable oil flow rate measurements even at high watercuts and high GVF's. This has until now been perceived a weakness by the users of all of the multiphase meters on the market.
High Quality ElectronicsThe electronics system in the topside multiphase meter is a ruggedized design, consisting of high quality components only.
The same high-grade electronics is used in topside and subsea meters. For subsea meters, a back -up system is offered to increase redundancy, and the subsea electronics has a number of housekeeping sensors to measure the conditions inside the electronics box:
• Humidity
• Water Ingress
• Temperature
• Pressure
• Shock / Vibration,
The electronics has an internal memory of 2 GB for raw data storage
