A Brief Study on Subsea Oil Storage Mode

In order to cut the cost of offshore marginal fields development, a new programme of subsea oil storage with CALM was put forward based on the actual demand of offshore oil field development. The basic working process of traditional oil & seawater replacement as well as separate replacement of oil & seawater was described. Besides, the feasibility and advantages for the subsea oil storage method were also mentioned, which can provide reference to the development of shallow marginal fields.
