使用生命周期评估 (LCA) 深入了解北海英国地区 Captain 油田重油开采的能源效率和环境绩效，该评估结合了能量-能量-投资回报率 (ERoEI) 的概念。LCA 允许将流程分为材料流和工作流，分别评估每个流的影响。在完整的论文中，作者将注水 (WF) 与聚合物驱 (PF) 作为主要开采策略进行了比较。
Captain 油田位于苏格兰阿伯丁东北约 145 公里处。油藏位于浅层，真实垂直深度约为 900 米，温度低至 31°C，压力低至 87 巴。主要挑战是 40-140 cp 的相对粘稠的石油。
Insights into the energy efficiency and environmental performance of the extraction of heavy oil from the Captain field in the UK sector of the North Sea are gained using life-cycle assessment (LCA), which incorporates the concept of exergy-return-on-exergy-investment (ERoEI). The LCA allows for separation of the process into material and work streams, assessing the effect of each separately. In the complete paper, the authors compare waterflooding (WF) to polymer flooding (PF) as primary extraction strategies.
The Captain field is approximately 145 km northeast of Aberdeen, Scotland. The reservoirs lie at shallow depths of approximately 900 m true vertical depth with correspondingly low temperatures of 31°C and low pressures of 87 bar. A primary challenge is the relatively viscous oil of 40–140 cp.
