项目摘要

The increasing global energy demand and decreasing hydrocarbon production from conventional resources have motivated the industry to produce hydrocarbons from unconventional resources. As hydraulic fracturing operations in Canada increase, it is becoming important to enhance the efficiency of these operations. Canada has massive unconventional resources with an estimated 425 billion barrels of shale and tight oil in-place in Alberta alone. Although horizontal drilling and multi-stage hydraulic fracturing have boosted hydrocarbon production, primary oil recovery factors from unconventional resources is very low (5-10% of the original oil in-place). The oil industry needs to apply enhanced oil recovery (EOR) techniques to improve this recovery factor. Surfactant solutions and natural gas have been considered as potential EOR fluids to improve oil recovery factors from unconventional reservoirs The proposed research aims to conduct systematic laboratory experiments for evaluating two different approaches to improve oil recovery factors from unconventional reservoirs. First is adding surfactants to fracturing fluids for EOR while fracturing. Second is cyclic injection of natural gas (Huff-n-Puff) after fracturing operations. One post-doctoral fellow, one PhD student, and one MSc student will conduct the three phases of this research, namely wetttability evaluation, surfactant EOR, and natural gas EOR. These phases involve systematic laboratory experiments on rock and fluid samples from East Duvernay and Eagle Ford Formations which are both carbonate-rich source rocks. The University of Alberta team will collaborate with industry experts in CNOOC International and Outlier Resources to: i) develop optimal formulations for fracturing and EOR fluids scenarios and ii) optimize operational parameters. The research team will acquire critical technical expertise to be well-poised to join the Canadian oil and gas industry, and continue the responsible development of the nation's unconventional oil and gas resources.

全球能源需求不断增长并减少传统资源的碳氢化合物生产，促使该行业从非常规资源中生产碳氢化合物。随着加拿大的液压压裂操作的增加，提高这些操作的效率变得越来越重要。加拿大拥有大量的非常规资源，仅在艾伯塔省就有4250亿桶页岩和紧密的石油。尽管水平钻孔和多阶段的液压压裂促进了烃的产生，但非常规资源中的原油回收因子非常低（占原始油的5-10％）。石油行业需要采用增强的石油回收（EOR）技术来提高这种恢复因素。表面活性剂溶液和天然气被认为是从非常规储层改善石油回收因子的潜在EOR流体。拟议的研究旨在进行系统的实验室实验，以评估两种不同的方法，以改善非常规储层中的油回收率。首先是在破裂时将表面活性剂添加到破裂的液体中。其次是破裂操作后自然气体（Huff-n-Puff）的循环注入。一名博士后研究员，一名博士生和一名MSC学生将进行这项研究的三个阶段，即Wettttability评估，表面活性剂EOR和天然气EOR。这些阶段涉及来自East Duvernay和Eagle Ford地层的岩石和流体样品的系统实验室实验，它们都是富含碳酸盐的源岩。艾伯塔大学（University of Alberta）团队将与CNOOC International和Outier Fluser Resources的行业专家合作：i）开发针对破裂和EOR流体方案的最佳配方，ii）优化操作参数。研究团队将获得关键的技术专长，以备付良好，以加入加拿大的石油和天然气行业，并继续对美国非常规石油和天然气资源负责发展。
