The project will identify improved recovery opportunities in the early stages of field development planning, such that facility and well designs can be optimized to take advantage of those opportunities. Additionally, opportunities for improved recovery in producing fields will be assessed, as will current and near-future technologies for improved recovery. The project will include characterization of deepwater and ultra-deepwater reservoir assets and compile and categorize key causes of trapped and remaining hydrocarbons in such reservoirs. The prioritization of technology gaps in improved recovery methods will also be addressed as specifically related to deepwater and ultra-deepwater reservoirs, with the aim of identifying leading concepts for future research, investment, development, testing and deployment /application.
