GUILDFORD, UK -- Opus has completed a solids characterization project for Wood Group on behalf of Hess in the UK North Sea.
The £30,000 ($49,000) contract involved assessing the quality of fluids within the water treatment system onboard the Triton FPSO. The main aim was to characterize the solids passing through the entire plant.
Opus was asked to identify the levels, source and distribution of any solids, as the operator suspected that very fine solids were having a negative impact on separation performance.
Another task was to investigate whether a primary flocculent would help reduce the quantity of oil-covered solids discharged as part of the produced water stream.
Opus uncovered complexities in chemical reactions between the fluids and the produced chemicals, which may have led to varying types of solids being generated in the process system.
The operator will use the resultant data to provide baseline criteria for design of future solids-handling equipment on the platform, and to determine whether changes can be implemented to improve the current processing situation.
