This new real time digital flow profiling system is designed to aid increased production, reduce operating costs, and improve recovery.

The system is suited for these well types:

  • Conventional and complex.
  • Multilateral.
  • Intelligent oil or gas producer-injector.
  • Long horizontal.
  • Ones with infrequent or no production logging technology (PLT) deployment.
The firms says its system provides continuous PLT-type data in 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, the company notes. Zonal flow allocation is determined using Sentinel distributed temperature sensing (DTS) technology. With a resolution of 0.01° C. every 1 m along the wellbore, the Sentinel system is usable in wells where other permanent monitoring solutions fail to identify thermal events, the company points out. The ability to provide updates every 10 sec also allows transient events to be analyzed, providing a new dimension in DTS interpretation.
