The WELL.DONE DTS system simultaneously monitors thousands of locations along the entire length of an onshore and offshore well.
Detection of well temperature profiles, reservoir monitoring, optimization of production and prevention of any unwanted operation conditions are examples of key functions of the temperature monitoring system. With its high optical budget and, it is virtually insensitive to high optical power losses associated with splice losses, subsea connectors and penetrators, and hydrogen darkening of optical fibers under the harsh conditions within a wellbore.
Applications
- Deep offshore wells
- Subsea wells
- Hydrogen darkened fibers
- Wet-mate connection wells
- Subsea Monitoring
- ROV umbilicals
- Risers
