KANFA Mator in cooperation with Institute for Energy Technology (IFE) has recently performed offshore testing of oil dehydration efficiency of three-phase separators. The separators had for some time experienced challenges with the separation of water from the oil phase resulting in problems in fulfilling the export oil specifications.
The following scope of work was performed:
- Injection and detection of gas, oil, water soluble radioactive tracers
- Gas / foam / oil / emulsion / water phase profile scanning
- Testing of oil / water fluid separability
- Measurement of possible slugging using a gamma densitometer
The findings were used as follows:
- Verify and eliminate reasons for the separation problems
- Identify possible short-term solutions, both stop and no-stop dependent
- Identify possible long-term solutions to meet the field life-time development
The main reason for selecting KANFA Mator and IFE for the study was our comprehensive process and radioactive tracer knowledge combined with operational experience. This combination secures best-for-purpose technical solutions, procedures and knowledge for optimal operation of the system.
