Abstract: With the increasingly discover of subsea oil and gas resources and the increasingly mature technology of subsea production systems， China National Offshore Oil Corporation （CNOOC） is rationally promoting development of newly discovered oil and gas field as well as the marginal oil and gas fields. It is very important to make sure the development design is technically feasible and the economic benefits which will determine whether the project could be implemented. Satellite well tieback to the original production system is cost saving plan for newly discovered oil and gas field. This paper studies the possible tieback scenarios and the key factors which will affect the feasibility of satellite well tieback. Solutions and suggestions are provide for future tieback project as reference.

Key words: subsea production system, satellite well, tieback, feasibility study
