Feasibility Study on Offshore Polymer Flooding, Forecasting Production Through Integrated Asset Modelling, A Technical and Economic Approach

摘要

Substantial percentage of current world oil production derives from mature fields and the rate of replacement of the produced reserves by new discoveries has been declining in the previous years. In order to sustain such upsurge in the demand for economical energy throughout the world, the recoverable oil resources in known reservoirs can be produced economically by applying EOR techniques. The following work is a comprehensive review of offshore polymer flooding through Integrated Asset Modelling (IAM). Polymer flooding has been one of the emerging EOR techniques in offshore environment in the recent decades. The pilot implementation of polymer flooding has proved to be challenging due to the difficulties associated with the operational facilities and the high Capital Expenditure (CAPEX) required to initiate the project. Coupling the IAM technique to such project would provide valuable insight to the current and future field production levels and expected operating conditions. IAM can add essential values in areas of field and well optimization, production forecasting, operational decision making and effect of extending field life on surface and subsurface facilities.
