Delivering a new water injection solution in the North Sea

摘要

Shell UK's efforts to reduce oil-to-sea discharge at Nelson field,120 km offshore Aberdeen in the Central North Sea,to comply with OSPAR regulations,have been complicated by the heavily corroded state of the Nelson water injectors.The state of these injectors posed a major challenge to successfully recovering the slot and executing a workover,which would allow produced water to be re-injected into the reservoir instead of being discharged to the sea.
