Innovative riser solutions for problematic well fluids

摘要

As deepwater exploration expands to new provinces, operators are finding increasing numbers of heavy oil res-ervoirs. Flow assurance challenges can be tough for conventional deep-water fields, but with heavy and waxy oils this issue becomes more complex. The industry continues to devise solutions such as improved insulation material for flow-lines and risers, gas lift techniques or low dosage hydrate inhibitors. Not all, however, can be applied to situations where heavy and waxy oil is present.
