.... The economic viability of these fields needs to be demonstrated or else they will be left stranded. Gas field developments entail numerous multifaceted issues related to the transported fluid such as: pressure drop, liquid hold-up, hydrates, corrosion and sand. The recent subsea technology development, Pseudo...
