System monitors flows in entire
reservoir
As well as monitoring the flow distribution in production and injection wells in real-time, the system also provides information often not accessible with traditional production logging technology.
Sensornet has developed a real-time digital flow profiling system which is set to aid increased production, reduce operating costs and improve recovery The company has developed the application with FloQuest, and it can accurately locate fluid entry points across an entire reservoir and identify fluids present
The system provides continuous PLT-type data in highly deviated and complex wells without the costs, risks and deferred production issues associated with conventional logging techniques.
As well as monitoring the flow distribution in production and injection wells in real-time, the system also provides information often not accessible with traditional production logging technology.
Traditional techniques often only provide a snapshot of what is really happening in the well and are potentially more expensive to run.
Zonal flow allocation is determined using Sensornet's Sentinel Distributed Temperature Sensing (DTS) technology.
With a resolution of 0.01C every 1m along the wellbore, the Sentinel system is suitable for wells where many other permanent monitoring solutions fail to identify thermal events.
The ability to provide updates every 10 seconds also allows transient events to be analysed.
The digital flow profiling system was recently deployed by a Middle East operator to understand flow distribution in a complex well.
By monitoring the well using the industry-leading Sentinel acquisition unit, Sensornet identified accurate flow distribution and delivered a system to achieve total coverage of the well with no further impact on installation and operation.
Within minutes of running the completion, the digital flow profiling solution provided real-time data gathering and interpretation and complete temperature profiles were captured, validated and delivered to the client in real-time.
Compared to the alternative of a horizontal well intervention on coiled tubing, the operator saved more than US $300,000 on service company charges.
Central to the digital flow profiling system are the advanced interpretation capabilities provided by the FloQuest software.
A highly efficient data management and visualisation front end enables rapid data analysis and processing.
With comprehensive flow and thermal simulation engines FloQuest enables the accurate inversion of DTS data to flow distributions, providing Virtual PLT information from temperature profiles.
Sensornet Chief Executive Officer Neale Carter said: "The correct analysis and interpretation of flow distribution and content in oil and gas wells can have a significant impact both financially and logistically on a well's production life and, ultimately, the success of an operation".
"With conventional technology there is a gap between what an operator believes is occurring along the well and what is actually happening".
"Our innovative technology and the digital flow profiling application close this gap and enable full understanding of flow contribution in real-time".
"Digital flow profiling provides a better understanding of the zonal properties of a well and a dramatic improvement in response to production or injection changes which can provide real benefits to the operator in terms of reduced downtime and optimised production and injection rates".
