Using sonar flow meters as part of an integrated well intervention strategy

In Brief
Using Expro’s sonar flow meters as part of an integrated well intervention strategy
Product Line
Meters
Objectives
  • Well intervention offers the potential to improve and/or extend the production profile of a well in production
  • Expro Meters aims to help operators increase safety and minimise the cost of intervention whilst improving well economics
  • Decisions on intervention programmes are often made with limited and outdated production data 
Expro Excellence
  • Technology used: SonarTest™; ActiveSONAR™ flow meter; PassiveSONAR™ flow meter; Well Test Studio™
  • Sonar meters deployed using Expro’s SONARTest service: small footprint of kit and ancillary equipment
  • Expro Meters field technicians deployed to install meters, obtain data, report preliminary rates at the well site and produce a full well test report pre and post intervention operations
  • Non-intrusive – clamp-on and requires no modification of the surface flow lines
  • Sonar meters have been successfully deployed in intervention campaigns employing the following intervention techniques:

–  Water wash halite removal

–  Batch foam treatment

–  Coiled tubing nitrogen lift gas well deliquification

–  Tubing plug zonal isolation

–  Cement squeeze zonal isolation 

Value to client
  • Cost-effective individual well surveillance
  • Data gives the wells team the opportunity to evaluate individual well performance and feed the preliminary data into the intervention planning process
  • Ability to avoid the unexpected and develop targeted campaigns for each well
  • Minimises the number of well intervention operations – reducing costs and NPT
  • Expro’s sonar meters have successfully diagnosed falling production associated with:

–  ESP failure

–  Storm choke failure

–  Halite build up

–  Liquification of gas wells

–  Packer failure – cross flow between zones
