The Libra Consortium, led by Brazil’s Petrobras, has developed a method of separating carbon dioxide from reservoir fluids at the seafloor rather than the FPSO topsides.
This paper outlines issues to be resolved during facility design and provides guidelines, calculations, and examples for sand-handling steps to be implemented after separation.
Over 1,000 hours of remotely monitored continuous production was achieved on an unmanned platform—a first for standalone offshore solids management in the North Sea.
