Decommissioning Costs Can Be Reduced

摘要

Many offshore decommissioning costs are higher than necessary because of decisions made during the initial engineering and construction for an oil or gas field. Economics for a 60,000-BOPD oil field show that a reduction in decommissioning costs of 50% can increase the project net present value (NPV) by 13%. A 5-year range of decommissioning data collected from throughout the world has been studied. Key areas have been identified in which decisions made during design affected the eventual decommissioning costs.
