Crude Metering and Measurement Systems Course
Introduction:
Metering systems are implemented to improve the precision of crude oil measurements and mitigate losses resulting from measurement discrepancies or errors. It is crucial to understand the meters, calibration procedures, and measurement techniques in order to effectively study and manage these systems.
Course Objectives:
The course addresses the concepts of custody transfer metering, the principle of allocation in shared facilities, and the general operating principles of custody transfer instruments:
- Flow meters (orifice, turbine, ultrasonic, venture, corilis) Densitometers
- Pressure / temperature / differential transmitters
- Automatic samplers
- BS & W measurements
- Chromatography
- Meter proving and instrument verification / re-certification
- Calculation routines and verification of flow computers
- Implementation of international standards
- Generic operating and reporting procedures
- The function of the pipeline and regulatory auditors
- Review of typical fault conditions
Who Should Attend?
Maintenance technicians, Supervisors, and Engineers.
