FibreDip™ sensing cable
Sensornet's FibreDip™ temporary (or semi-permanent) cable range is based on a ruggedised cable construction providing the operator with a clear view of what is happening in the reservoir. The FibreDip™ cable has been designed to:
- Be easily deployed
- Be highly durable
- Withstand high temperatures (up to 300 deg C)
- Withstand re-deployment
- Not affect the temperature equilibrium of the well.
About the FibreDip™ deployment method
Sensornet's revolutionary FibreDip™ deployment method is a flexible well integrity monitoring solution of the entire thermal observation well without the need for tubing, or a service rig or a hoist. Sensornet’s FibreDip™ system is an extremely versatile Digital Monitoring solution. The easily deployed, self-supported system is used to understand the boundaries and communication layering of the steam front while condition monitoring the casing integrity of the surrounding production wells. To date FibreDip™ has been successfully installed by Sensornet in Alberta, Canada and Oman.
Vertical wells that benefit from Sensornet’s FibreDip™ monitoring solution include
- Thermal observation wells
- Limited rig / hoist availability / accessibility
- Remote well locations
The FibreDip™ system is an extremely effective, retro-fittable installation technique that eliminates the need for a tubing conveyed system. Once the completion is installed, the Sensornet team can install the FibreDip™ system at any time, without delay to operations. The FibreDip™ sensing cable is reeled into the well by itself using a sinker bar system in conjunction with a spooler unit and a sheave wheel (suspended on shear legs or wireline boom) and is a low-risk, quick installation method. Depending on customer requirement, the FibreDip™ system can be combined with a pressure gauge upon request.
Benefits of FibreDip™
The self-supporting FibreDip™ system has a number of key advantages over a tubing conveyed system or periodic intervention by wireline temperature
log namely:
- Permanent installation that can be retrieved months or years later and installed elsewhere
- Continuous condition monitoring of thermal process and well integrity
- Deployed without the need for a workover rig or hoist at well site
- Retro-fit into existing completions
- Production tubing is not necessary
- System can be deployed in any hole size – either cased or open hole
- No tubing hanger or bypass ports required for the sensing cable
- Simple and fast, one-time sensing cable installation
- System is retrievable and can be redeployed in other wells
- No modification to existing wellheads – with no requirement for by-pass ports to be drilled
