Expro Excellence
Meters
Flowline integrity and leak detection surveillance
Objectives
  • Expro was approached to measure stablised crude oil and entrained water from eight flow stations
  • The customer previously experienced leaks on their pipelines and were now looking to monitor volumetric rates to detect or identify any leaks real time to avoid pollution to the environment
  • The project involved the monitoring of volumetric rates at point of export and volumetric rates at point of import at each successive flow station in the field
  • The customer was interested in using a non-intrusive clamp on metering to avoid any facility modifications or production shut downs
Expro Excellence
  • Expro provided a turnkey operation, where Expro undertook a site survey and operations planning and execution across the Nigeria delta, with limited access
  • Rapid mobilisation of SONAR meters to meet customers urgency in identifying leaks in system and minimise the environment impact
  • Meters left unattended for extended period of surveillance to ensure any discrepancies in instanteous rates were averaged across the desired period of investigation
  • Meters worked in process conditions not always single phase, with oil, water and at times free gas, identified in the SONAR meter on-board diagnostics
Value to client
  • SONAR meter installed without facility modifications or production shut downs
  • Mulitple lines surveyed simultaneously to get a field wide balance on the volumetric rates
  • Mulitiple flowline sizes and volumetric rates without dedicated meter sizes
  • Customer identified a discrepancy of 2000 bopd in a 5000 bopd line
