Oil companies are focused on asset value maximization with a view to augment overall hydrocarbon recovery. This goal remains a notable challenge to execute in mature fields which contribute to majority of the world's global oil production today. An integrated structured approach from the multidisciplinary skill set is the key for redeveloping mature fields.The present paper focus on the efforts spent on a brown oil field located approximately 35 km offshore in a water depth of 90 m with more than 35 years of production. To date the field is in production with 8,000 bopd and a 85% watercut.The concession License expiration and the facilities ageing/deterioration forced a technical reevaluation of the possible development scenarios for the field with the aim to maximize the recoverable reserves and minimize the capital expenses.Based on high level of synergy amongst the teams and thanks to the workflow adopted, the identification of "still recoverable" under-drained potential has resulted in leading to a new development phase in the mature asset.The paper will cover the full spectrum of static and dynamic review including well location placement/ trajectory/completion design, artificial lift requirements, reservoir pressure support needs, evaluation of tertiary recovery schemes while keeping into account economic feasibility together with Concession License expiration. Results and conclusions together with lessons learnt that can be applied to similar assets globally will also be presented.
