Suncor Energy Inc (Suncor) is a leading international energy company and a major player in Canada's oil sands, carbon capture and storage, and alternative energy (wind and solar power). Over the next 3 decades, as Canada's oil sands transition to net-zero solutions and meet Canada's climate goals, they're expected to contribute $3 trillion to the GDP and $1.7 trillion in royalties. These revenues contribute to government spending on infrastructure, social services, medical, educational, cultural and other important programs for all Canadians. Suncor is partnering with the Southern Alberta Institute of Technology's (SAIT) Centre for Energy Research and Clean Unconventional Technology Solutions (CERCUTS) research group to develop a novel analytical method and laboratory procedures to characterize diluent mixtures and fluids recovered by Expanding Solvent Steam Assisted Gravity Drainage (ES-SAGD). ES-SAGD involves a small volume of solvents co-injected with steam to increase bitumen recovery, but for it to be economically- and environmentally-efficient, it is critical to reduce energy and steam requirements and minimize diluent loss to the oil sands and surrounding formations.A primary challenge is current measurement methods assume produced diluent has the same compositional distribution as injected diluent, creating inaccuracies. The key objective is to develop a novel analytical method which includes validation with associated laboratory procedures to characterize diluent mixtures and fluids recovered by ES-SAGD. The outcome will be a specialized methodology for the accurate and reproducible solvent determination of produced fluids for recycle. With this system, the commercial viability of in-situ bitumen recovery using solvent technologies, such as ES-SAGD, will become more verifiable, reliable, energy- and environmentally- efficient and marketable. This unique in-situ technological know-how, if transferred for other applications such as harnessing geo-thermal energy, will promote Canada's position as a technology leader.

森科尔能源公司（Suncor Energy Inc）是一家领先的国际能源公司，也是加拿大油砂、碳捕获和储存以及替代能源（风能和太阳能）的主要参与者。在接下来的30年里，随着加拿大的油砂过渡到净零解决方案并实现加拿大的气候目标，预计它们将为国内生产总值贡献3万亿美元和1.7万亿美元的特许权使用费。这些收入有助于政府在基础设施、社会服务、医疗、教育、文化和其他重要项目上的支出。森科尔是与南阿尔伯塔理工学院（SAIT）能源研究中心和清洁非常规技术解决方案（CERCUTS）研究小组合作，开发一种新的分析方法和实验室程序，以表征稀释剂混合物和液体回收膨胀溶剂蒸汽辅助重力泄油（ES-SAGD）。ES-SAGD涉及与蒸汽共注入少量溶剂以提高沥青采收率，但要使其具有经济和环保效益，降低能源和蒸汽需求并最大限度地减少稀释剂对油砂和周围地层的损失至关重要。主要挑战是当前的测量方法假设产出的稀释剂与注入的稀释剂具有相同的成分分布，从而产生不准确性。主要目标是开发一种新的分析方法，包括验证相关的实验室程序，以表征稀释剂混合物和ES-SAGD回收的液体。其结果将是一个专门的方法，用于准确和可重复的溶剂测定回收生产的流体。有了这个系统，使用溶剂技术（如ES-SAGD）进行现场沥青回收的商业可行性将变得更加可验证、可靠、节能和环保，并且更有市场。这种独特的现场技术专门知识如果转让给其他应用，如利用地热能，将提高加拿大作为技术领先者的地位。
