Characterization study for North Sea reservoir
Twelve different well streams from a North Sea reservoir were characterized to a unique set of 7-8 pseudo-components. The compositions covered gas condensates, near critical fluids and oil compositions. The reservoir pressures were of the order 900 bar. PVT data for each of the 12 fluids was matched and Eclipse Comp files generated for each stream.
Asphaltene precipitation study
The potential for asphaltene precipitation in a Venezuelan field was evaluated. Various production strategies were considered including natural depletion, natural gas injection and CO2 injection. It was found that each of these production strategies might lead to severe asphaltene precipitation problems.
QC of PVT reports
PVT reports for a field in Africa covering a period of around 25 years were evaluated and compared. In this evaluation the production from the field during the 25 years of production was to be taken into consideration. The purpose of the project was to provide a best estimate of the composition of the currently produced reservoir fluid and to generate corresponding Eclipse black oil input PVT tables.
Technical expert in arbitration
An Asian power plant claimed that the dewpoint of the natural gas delivered from a field offshore China did not meet the agreed specification. Too high dewpoints might cause severe damage on the gas turbines. The arbitration took place in London, UK. Compositional data for the gas delivered over a period of 7 months was evaluated and dewpoint simulations carried out to check whether the specification was met.
Evaluation of EOS model
An EOS model had been developed some years in advance for a field in the Middle East. The field was reach in H2S with large horizontal variations in H2S concentration. CO2 injection was planned to take place. The task was to evaluate the quality of the EOS model and to find out how well the EOS description matched more recent PVT data including CO2 swelling data.
