Production from offshore fields has been dominating in the past and will continue to dominate in the future. It is expected that more than 50% of the production will come from the deeper, waters. Most of the new discoveries in the Indian offshore have been marginal in nature, where economics dictate selection and application of production systems. As a part of the development, many wells are being completed subsea. Due to the marginal nature of the fields, the self flow tram these wells has been minimal, necessitatinq application of artificial lift at the earliest and in many cases right from the begining. In the present study, an attempt has been made to evaluate the suitability of the available lift systems with special reference to its application in marginal fields of Indian Offshore. Also, some case histories of applications of different artificial lift modes have been reviewed which provide important parameters to evaluate their suitability and the field proven technology.
