Schlumberger said that the WellWatcher BriteBlue harsh environment multimode fiber can be used as a distributed sensor for applications such as distributed temperature sensing or for high-speed communication between downhole sensors and a surface acquisition unit.
The firm said that the new generation fiber was designed especially for use in extreme heat and hydrogen environments. The new design and technology reportedly makes WellWatcher BriteBlue particularly suitable for thermal heavy oil recovery applications.
The WellWatcher Ultra distributed temperature system surface unit can acquire downhole temperature profiles. The versatile new system can reportedly measure up to 15km of fiber at a meter’s resolution, update data in just a few seconds, resolve temperatures to 0.01 degrees, and interrogate numerous fibers from one surface system.
Gabriel Tirado, business development manager-monitoring of Schlumberger Completions, said: Permanent in-well reservoir monitoring with WellWatcher is crucial for operators to improve production management and recovery, and identify and resolve problems quickly to reduce downtime and related costs.
