The wellhead pressure of the subsea trees could be reduced dramatically by using subsea compressor technology, thereby increasing the production of the target gas field and achieving better economic benefits. The subsea compressor boosting technology has been increasingly valued and favored by domestic and foreign oil companies in recent years. This paper study on the development of the subsea compressor boosting technology and compare the technology roadmap of different subsea compressor to determine better solution for projects in Nanhai Sea in order to provide reference for future potential subsea compressor boosting project.
