A method of mapping the flowing temperature profile of a zone.


  • TCP gun fire and performance verification
  • Flow allocation during DST
  • Cross flow detection and monitoring, especially during build-ups
  • Production and injection profiles for completed wells
  • Frac performance observation/gravel pack deployment


  • Wireless system with no wellhead or packer penetrations
  • Deployable on perforating guns
  • Autonomous tools permit tool redundancy at each location
  • Duplex communication for data collection from multiple devices


  • Reservoir profiling below obstructions such as artificial lift pumps
  • Continuous flow profiling throughout operation
  • Combinable with FLOW-SURE devices to manage your well
  • Deployable beneath permanent packers without failure prone wet-connects
