Offshore/subsea systems
This paper discusses waterflooding and field-development implications of subsea seawater treatment for improved oil recovery.
This paper presents an engineering solution tailored for shallow-water oilfield development in Bohai Bay, addressing the confluence of spatial constraints, marginal economics, and environmental conditions that have rendered such reserves stranded.
This paper details the design and implementation of a subsea multiphase pump solution deployed in the Atlanta field designed to maximize reuse of existing subsea and topside equipment.

In the fourth development phase, a planned tieback would connect resources from two North Sea discoveries to existing infrastructure at the Johan Sverdrup field, pending project sanction.
-
Production delivered by the subsea artificial lift system will equal that obtained by drilling two new wells, according to BP.
-
This paper describes the use of encapsulated polymer technology to address the issues of shear degradation and injectivity integrity faced in the application of polymer flooding in an offshore development context.
-
This paper describes the successful deployment of flexible coiled tubing technology in an oil-producing well of the offshore Frade field in Brazil’s Campos Basin.
-
New technical papers suggest advanced robotic systems may not be far away from broad adoption for a large share of offshore inspection and intervention.
-
While often associated with smaller discoveries, subsea tiebacks are playing a growing role in contributing to the broader energy mix.
