merson Process Management has launched the latest version of its production management system, Roxar Fieldwatch 3.0. It comes with a number of new


intelligent reservoir management features in the areas of sand erosion control and will provide important operational data to production and reservoir engineers as they look to increase production performance. Operators receive thousands of false alarms from erosion probes each year, with changes in temperatures, production regimes and other noise such as electromagnetic interference being the main causes. Roxar Fieldwatch 3.0 comes with


innovative smart alarm software consisting of a new filtering and temperature compensation algorithm as well as signal stability and trend analysis software that assesses how trustworthy each sand erosion measurement is. Te result will be a dramatic reduction in the number of false alarms from erosion probes. Testing of the smart alarm software on historical data from a North Sea field has seen the suppression of 99 per cent of false alarms, while retaining 100 per cent of the genuine alarms.


Virtual erosion sensors Fieldwatch 3.0 will also enable operators to install virtual erosion sensors within their production system – particularly to monitor bends, T-bends and reducers in areas where it is difficult to deploy physical sensors. With the virtual sensors, users can


configure the geometry and input pressure and temperature values that best represent the virtual sensor’s position and analyse in Fieldwatch 3.0, as they would with physical sensors.


While not as accurate as real sensors, the virtual erosion models can calculate

important production information by inputting flow information, pressure and temperature data. “Fieldwatch 3.0 is all about building


greater intelligence into production management and giving production and reservoir engineers the tools and data to make better informed decisions,” said Rune Sorhus, md of Roxar Fieldwatch at Emerson Process Management. “Te new features we are announcing today will not only help operators confront the age-old threats of sand and corrosion but also generate crucial improved information for reservoir and production engineers in relation to metering, production allocation, and choke settings. Te end result will be more intelligent management of the reservoir and its processes, the transformation of data into intelligent and easy to use information, and increased production.”


Filtering functions Roxar Fieldwatch 3.0 also comes with a number of improved usability features including new filtering and search functions where users can filter out pressures and well structures, for example, and faster access to recently viewed items. Different production systems can also be grouped together more intuitively in terms of how they relate to groups of wells and instruments. Roxar Fieldwatch collects, monitors, visualises and analyses data from a range of sensors and instruments for operators to have a more complete picture of the reservoir and production system, and provides data input to reservoir and production engineers when making reservoir management decisions relating to metering, production allocation or choke settings. It includes a series of custom-built modules in the areas of flow assurance,
