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.****

已经沿其长度沿着在多个阶段中进行水力压裂的长水平威尔斯井已经能够生产非常规资源，例如页岩气。 目前的工业实践是使用许多压裂阶段（通常为20-30）和大量的压裂流体（通常为水基的，100 m3）来最大化来自这些威尔斯井的产量，使得这种实践是非常能量密集型和资源密集型的。 该项目旨在使运营商能够减少阶段数量，同时最大限度地提高产量，因此具有环境和经济影响。 这些目标将通过使用本文开发的新技术识别沿着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.（7 G），BitCan Geosciences & Engineering Inc.（BitCan）和Rocsol Technologies Inc.（Rocsol）. 7 G是一家运营公司，寻求提高其非常规资源开发的效率，同时减少其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是一家咨询公司，专门从事可用于评估长水平威尔斯井的试井方法。 他们的技术将在这项研究中得到试验和证明，这可能会增加未来的咨询机会。 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，以协助评估水平威尔斯的岩石质量。 为此目的使用Rocsol软件的示范应能增加销售机会。** 最后，该项目对加拿大人具有战略重要性。 面对大宗商品（石油和天然气）价格低迷，加拿大的能源部门一直在努力保持竞争力。 此外，该行业需要解决和减轻水力压裂作业的环境后果。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。
