Advanced characterization of multi-fractured horizontal wells completed in western canadian tight formations

长水平井在其长度上进行多级水力压裂，使得页岩气等非常规资源得以开采。目前的行业做法是使用多个压裂段（通常为20-30段）和大量压裂液（通常为水基，100立方米）来最大限度地提高这些井的产量，这使得这种做法非常耗费能源和资源。该项目旨在帮助作业者在最大限度地提高产量的同时减少压裂段的数量，从而实现环境和经济效益的双赢。这些目标将通过使用本文开发的新技术识别沿井的岩石质量变化来实现。该项目对我们的工业合作伙伴Seven Generations Energy Ltd （7G）、BitCan Geosciences & Engineering Inc （BitCan）和Rocsol Technologies Inc （Rocsol）具有战略意义。7G是一家寻求提高非常规资源开发效率的运营公司，同时减少水力压裂作业对环境的影响，目前的提案满足了这些需求。BitCan是一家专门从事测试方法的咨询公司，可用于评估长水平井。他们的技术将在这项研究中得到试验和证明，这可能会在未来带来更多的咨询机会。最后，Rocsol是一家专门从事钻井优化软件的数据分析公司，该软件将在本研究中实施，以协助评估水平井的岩石质量。演示使用Rocsol的软件用于此目的应导致增加的营销机会。最后，这个项目对加拿大人来说具有战略意义。面对低油价（石油和天然气），加拿大的能源部门一直在努力保持竞争力。此外，油气行业需要解决和减轻水力压裂作业对环境的影响。目前的提案提供了一个环保的解决方案，以帮助萎靡不振的加拿大石油工业。

Long horizontal wells that have been hydraulically-fractured in multiple stages along their length have enabled production of unconventional resources such as shale gas. Current industry practice is to use many fracturing stages (typically 20-30) and large volumes of fracture fluid (typically water-based, 100s of m3) to maximize production from these wells, making this practice both very energy- and resource-intensive. This project aims to allow operators to reduce the number of stages while maximizing production, and hence has both environmental and economic implications. These goals will be achieved by identifying rock quality variation along the well using new techniques developed herein. This project is of strategic importance to our industrial partners Seven Generations Energy Ltd. (7G), BitCan Geosciences & Engineering Inc. (BitCan), and Rocsol Technologies Inc. (Rocsol). 7G is an operating company seeking to improve efficiency in the development of their unconventional resources while reducing the environmental impact of their hydraulic fracturing operations - the current proposal addresses these needs. BitCan is a consulting company specializing in well-testing methods that can be used to evaluate long horizontal wells. Their technologies will be trialed and proved in this research, potentially leading to increased consulting opportunities in the future. Lastly, Rocsol is a data analytics company specializing in drilling optimization software that will be implemented in this study to assist with evaluation of rock quality in horizontal wells. Demonstration of the use of Rocsol's software for this purpose should lead to increased marketing opportunities. Finally, this project is of strategic importance to Canadians. Canada's energy sector has struggled to be competitive in the face of low commodity (oil and natural gas) prices. Further, the industry needs to address and mitigate the environmental consequences of hydraulic fracturing operations. The current proposal offers an environmentally-friendly solution to aid the flagging Canadian oil industry.
