Optimizing Gas Condensate Subsea Tiebacks: Lessons Learned from Unload to Host Operations
J. Zhang,
A. G. Shepherd
Abstract:Gas condensate subsea tiebacks increasingly favor Unload to Host (U2H) operations over traditional Unload to Rig for enhanced execution efficiency and cost reduction. They further eliminate the need for temporary floating production units to partially unload wellbore liquids/solids and introduce first gas with flaring. While U2H brings significant benefits like HSE risk mitigation, it also poses integrity and operability challenges to new and existing facilities. This paper will present case studies and lesson… Show more
