Methods for Early-Phase Planning of Offshore Fields Considering Environmental Performance

Extraction and processing of oil gas with current technologies is energy- carbon-intensive as well the manufacture, transport installation facilities needed for production. Nowadays, there an emphasis on reducing emissions energy usage to help mitigate climate change. In this work we demonstrate test methods decision-support in early-phase field planning based proxy modeling optimization. An optimization model developed determine drilling production schedules, capacities that maximize a key performance indicator. The indicator linear combination NPV environmental variables, such carbon footprint CO2 emissions. weight each variable objective function adjusted by varying value constants. offshore Norwegian Continental Shelf used case study. Results show clear trade-off between economic performance. There are cases, however, where modest improvement can be achieved without significantly decreasing its value. paper offers comments observations about implementation inclusion constraints into early-field development planning.
