Sensornet and Ziebel sign agreement for wellbore DTS systems

Sensornet, provider of the world’s most advanced monitoring solutions, is pleased to announce a supply and cooperation agreement for Distributed Temperature Sensing (DTS) technology with Ziebel.

The supply agreement will allow further expansion of Ziebel's current fibre optic permanent downhole monitoring solutions as well as intervention services, and will strengthen Sensornet’s position as the industry leading supplier of fibre optic monitoring products and services.

The partnership enables Ziebel's intervention technologies and competencies to be combined with the industry’s most advanced DTS products and services from Sensornet. This allows for the provision of data management and interpretation services by FloQuest, enabling advanced analysis of DTS and other sensors for flow allocation, injection profiling, and well integrity monitoring.

Sensornet and Ziebel have also signed a new three year exclusive agreement to cooperate on the commercialization of the patented ZipLogTM wellbore optic surveying method. This game-changing well intervention methodology involves a semi-stiff carbon "rod" being pushed into live wellbores across production or injection intervals. This is a cost-effective and powerful alternative to logging with coiled tubing or well "tractors". The system logs downhole distributed temperature, point pressure and vibration in real time.

Neale Carter, CEO Sensornet, said: “I am delighted by these exciting developments and we look forward to further enhancing our disruptive technology offering to our clients in the oil and gas industry.

“The correct analysis and interpretation of flow distribution and content can have a significant impact both financially and logistically on a well’s production life and, ultimately, the success of an operation. This agreement will ensure that our technically advanced range of solutions ensures that every monitoring requirement is met.”

Henning Hansen, Corporate VP - Technology, Marketing and Business Development, Ziebel, said: “Having followed Sensornet closely for many years, I am very pleased to see Sensornet and Ziebel now forming this cooperation.

"Further strengthening the cooperation with Sensornet is a significant reinforcement of Ziebel’s vision to become a leading provider of systems improving reservoir drainage.
This technology cooperation, where Ziebel's leading edge wellbore technologies and competencies are merged together with Sensornet's industry leading fibre optic DTS products, will for Ziebel be a significant step forward in advanced wellbore monitoring and interpretation.“

Sensornet installs world’s first distributed fibre optic monitoring system in MRC well

Sensornet, the global provider of the most advanced monitoring solutions, has successfully installed the world’s first distributed fibre optic monitoring system in a Maximum Reservoir Contact (MRC) well for a major operator in the Middle East.

Regarded as the most complex well type ever monitored by a fibre optic DTS system, the system allows continuous monitoring of flow contribution from two side-tracks as well as the mother bore in the multilateral well.

Deployment in the 14,500ft well was achieved in less than two days, with the Sensornet SureSightTM cable passing through three permanent production packers and three Inflow Control Valves (ICV). Three field testable fibre optic splice assemblies were installed with no degrading effects on the measurement performance.

The DTS system also allowed each of the ICVs to be individually tested, confirming the correct sequence of operation as well as circulation and isolation. The safe, smooth and trouble free installation is testament to Sensornet’s field engineering experience, project management and design capabilities.

The system was continuously monitored, allowing testing and confirmation of completion accessories during all phases of the installation. During well clean-up, fluid displacement could be easily monitored, reducing rig standby time while providing a high degree of confidence in the downhole conditions before moving off location.

Neale Carter, Sensornet CEO commented: “The integration of our high performance instrumentation with practical oilfield expertise and advanced interpretation capabilities is now delivering our vision of virtual production logging. Client feedback, even during these early stages of the installation, has been fantastic and we are confident of massive growth in deployments as a result.

“Monitoring of zonal and lateral contribution is a key issue for the operator and by providing a permanently installed system the operator is now able to instantly act on phase breakthrough and rate changes. Sensornet’s permanent monitoring system provides the operator with continuous, real time information at a fraction of the intervention costs. The ability to have constant access to this production information enables reservoir and production engineers to make significant improvements in field recovery, production rates and reductions in produced water.”

DTS Monitoring in Plants and Refineries

The thermal and chemical processes that occur within reactor vessels and columns can slowly erode and weaken the structure of the vessel. This effect can be very localised and as this weakening occurs the skin of the vessel is reduced causing a potential point of weakness/failure. This weak spot will have a temperature signature which differs from the rest of the vessel and will result in a hotspot (or cold spot depending on the process). By detecting this hotspot early on, action can be taken to prevent any accidents and minimise any downtime for the plant.

Detect hotspots in reactor vessels early to prevent any potential failures

The Sensornet distributed temperature sensor can provide such an early warning system, thus improving overall safety of the plant. The Sensornet DTS will interrogate the fibre optic sensing cable which can be attached to the outside of the vessel thus providing a full temperature profile of the vessel. Typically this cable will be installed in a helical configuration on the outside of the vessel to provide maximum coverage. Sensornet offers a number of visualisation and communication options so that the operator can easily interpret the data and also integrate the DTS into their control system. Thus in the event of an alarm the Sensornet DTS can automatically activate the control system to take action.
