Sensornet develops fiber-optic distributed temperature cable range

ABERDEEN, UK -- Sensornet has developed a new high performance SureSight fiber-optic distributed temperature cable range that can withstand extreme heat and operate in the harshest downhole environments, according to the company.

Used for high temperature wellbore monitoring, the SureSight cables withstand temperatures up to 300º C (572º F), which are often experienced in steam assisted gravity drainage (SAGD) and cyclic steam injection (CSS) wells in steamflood reservoirs. By providing real-time permanent monitoring for enhanced recovery and proactive management, the technology marks a step change in performance from traditional technologies.

As an increasing number of wells are developed in hostile conditions, SureSight cables have been designed and optimized with double ended measurement capabilities. This is particularly important in hydrogen rich, high temperature installations as single-ended measurements become susceptible to changes in temperature caused by hydrogen ingress. This can present significant problems for operators as incorrect temperature readings can be produced.
