Customer challenges
- Expro was approached to measure stabilised 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
- Multiple lines surveyed simultaneously to get a field wide balance on the volumetric rates
- Multiple flowline sizes and volumetric rates without dedicated meter sizes
- Customer identified a discrepancy of 2000 bopd in a 5000 bopd line
