The deepwater/subsea market is in the early days of a long-duration upcycle, as operators seek to replenish baseload, low-decline-rate oil and gas production. In pursuing this goal, operators are seeking to further improve efficiencies and economics, so technical innovation remains crucial. This e-book collection of recent World Oil articles reflects advances in various deepwater/subsea categories, including tie-back engineering, casing drilling, well delivery, subsea umbilical installation, improved FPSO performance, deepwater MPD operations and riser life extension, among others.
