Subsea, or fully-submerged ocean oil & gas equipment, goes back to when “Shell completed its first subsea well in the Gulf of Mexico in 1961.” Given the difficulty in accessing this equipment, downhole measurements are essential in maintaining optimum production.

A quick, 2:18 video, Roxar Downhole Wireless PT Sensor System, shows how this pressure-temperature continuous monitoring solution provides oil & gas operators with a robust and proven system to validate well integrity.

This wireless pressure-temperature measurement monitors the B-annular space between the production casing and the next outer casing. This Roxar Downhole Wireless System technology has been proven in subsea production applications since 2013.

The system is installed directly onto the same cable as the Roxar downhole monitoring network. It transmits power and data inductively through the production casing to provide real-time pressure monitoring for the life of the well.

These measurements provide immediate alerts about well integrity issues such as casing pressure buildup. Early notifications help the operations staff mitigate the risk of collapse, loss of well control, or costly workovers.

Watch the video and visit the Roxar Downhole Wireless Systems page on Emerson.com for more on this technology and how it improves production and offshore safety, providing early high–pressures warnings, protecting casing integrity, and preventing pressure buildup.
