Wintershall Deploys Emerson Roxar System on Maria Field

Emerson’s latest Roxar downhole sensor system has been deployed on the Maria field offshore Norway, providing the field’s operator Wintershall with improved well integrity monitoring and offshore safety.

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 company explained.

The system, that has been tested at 225 degC/437 degF can withstand pressures of up to 1 380 Bar/20 000 Psi.

“After continued sales and further advances to the system, the Roxar downhole sensor solution has reached full maturity,” said Sturle Haaland, European sales director at Emerson Automation Solutions. “Operators will now have the information they need to make informed decisions on well integrity, adhere to regulatory requirements, ensure offshore safety, and enable their wells to produce at optimal levels.”

The Roxar downhole sensor system is powered using an inductive coupling system developed in-house. The sensor is installed externally to the steel casing and may be cemented in place in the well.

Continuous power and data to and from the sensor is then transmitted wirelessly through the steel casing to ensure maximum well integrity for the life of the well and enable any anomalies to be detected early and in real-time.
