完整的论文讨论了旨在提高阿拉斯加北坡重油采收率的第一个聚合物驱试验。经过 2.5 年多的聚合物注入，项目生产商的含水率下降了，从 65% 下降到了 15% 以下，带来了显着的效益。该研究的主要目标是开发一个稳健的历史匹配油藏模拟模型，能够预测未来的聚合物驱性能。
该试点计划的目标是 Schrader Bluff NB 砂岩中的一个孤立断层，配有两个水平注入井（J-23A 和 J-24A）和两个水平生产井（J-27 和 J-28）。水平井生产长度为4,200至5,500英尺，平均井距约为1,100英尺。项目井于2016年6月开始注水，累计注水采收率约7.6% 0.09 孔体积 (PV)。2018年8月，聚合物溶液注入开始。
The complete paper discusses the first polymerflooding pilot to enhance heavy oil recovery on the Alaskan North Slope. After more than 2.5 years of polymer injection, significant benefit has been observed from the decrease in water cut, from 65% to less than 15% in project producers. The primary objective of the study was to develop a robust history-matched reservoir simulation model capable of predicting future polymerflooding performance.
The pilot program targets an isolated fault block in the Schrader Bluff NB sands with two horizontal injectors (J-23A and J-24A) and two horizontal producers (J-27 and J-28). The producing lengths of the horizontal wells range from 4,200 to 5,500 ft, and the average interwell distance is approximately 1,100 ft. The project wells were put on waterflooding in June 2016, recovering approximately 7.6% of the original oil in place with a cumulative water injection of 0.09 pore volumes (PV). In August 2018, polymer solution injection commenced.
