Courtesy: EmersonEmerson's Roxar Downhole Sensor System has been deployed on the Maria field in offshore Norway, providing the field's operator Wintershall with improved well integrity monitoring and offshore safety. The latest deployment of the system provides crucial integrity data and measures online and real-time pressure and temperature information from behind the casing in subsea production wells to offshore operators on the status of their well barriers and casing. The pressure and temperature monitoring system allows Wintershall to verify that the predicted pressure buildup falls within the design criteria, and an alarm trigger point is implemented in case pressures that are potentially outside the system design are reached.

The Roxar Downhole Sensor System also comes with new advances that enable operators to access online displays and trending of previously unreachable temperature and pressure subsurface data behind the well casing and achieve online integrity verification without any impact on production. The added knowledge on pressure and temperature dynamics delivered by the Roxar Downhole Sensor System's highly accurate quartz gauges in previously unreachable parts of the completion has also led to a better understanding and confidence in operators' well integrity strategies. The system helps ensure wells meet integrity monitoring standards, such as API RP90 and NORSOK D-010.
