Production Optimisation for Second Stage Field Development Using ICD and Advanced Well Placement Technology (SPE-113577)

摘要

The paper covers the application of new technology drilling and completions equipment in horizontal wells to maximize production and recovery in a thin oil rim. The parallel process applied to the engineering design, drilling operations, real-time decisions, and results are presented. As part of the second stage development of a mature oil field offshore Malaysia, a shallow and previously un-produced target was identified. Initial engineering and reservoir studies identified two horizontal wells as the optimum development strategy. However, to ensure maximum production and recovery a 2,000ft lateral was required. Further detailed studies indicated that for the long lateral to be successful, well placement with respect to reservoir boundaries and fluid contacts, and open-hole sand screens of a high mechanical integrity would be critical.Additionally, in order to ensure even oil production and limit early water and gas production In-flow Control Devices would be required as part of the completion.
