Press Release Summary: Sensornet, the global provider of the most advanced
monitoring solutions, has developed a new high performance SureSightTM fibre-optic
distributed temperature cable range which can withstand extreme heat and operate in
the harshest downhole environments.

Press Release Body: Sensornet, the global provider of the most advanced monitoring
solutions, has developed a new high performance SureSightTM fibre-optic distributed
temperature cable range which can withstand extreme heat and operate in the harshest
downhole environments.

Used for high temperature wellbore monitoring, the SureSightTM cables withstand
temperatures up to 300ºC (572ºF), 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, SureSightTM
cables have been designed and optimised 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.

The unique cable construction provides a number of benefits over the use of standard
fibre optic technology. While multiple layers provide a pressure barrier to prevent
damaging hydrogen ingress, the latest generation of optical fibres minimise the
effects of hydrogen darkening with chemical composition and coatings. The rugged
cable design means the integrity of the DTS system can be monitored during
installation and information sourced on stimulant/frac fluid placement.

John Perrin, Sensornet VP North & South America, said: "The SureSightTM cable range
represents the latest offering in analysis systems for downhole technology. Our
engineers have developed a unique technology for the high temperature market and I
am confident it will have a major impact on the industry. High temperature methods
are increasingly being used to develop reservoirs and SureSightTM provides operators
with the ideal monitoring solution."
