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

长水平井沿线经过多个阶段的水力压裂，使页岩气等非常规资源得以生产。目前的行业做法是使用多个压裂阶段(通常为20-30个)和大量的压裂液(通常为水基，100立方米)来最大限度地提高这些油井的产量，这使得这种做法非常耗能和资源密集型。该项目旨在允许运营商在最大限度提高产量的同时减少阶段数，因此具有环境和经济影响。这些目标将通过使用这里开发的新技术确定油井沿线的岩石质量变化来实现。**该项目对我们的工业合作伙伴七代能源有限公司(7G)、BitCan地球科学与工程公司(BitCan)和Rocsol Technologies Inc.(Rocsol)具有战略重要性。7G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是一家专门从事可用于评估长水平井的试井方法的咨询公司。他们的技术将在这项研究中得到试验和验证，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，以帮助评估水平井的岩石质量。为此目的使用Rocsol软件的演示应该会带来更多的营销机会。**最后，这个项目对加拿大人具有战略重要性。在大宗商品(石油和天然气)价格低迷的情况下，加拿大的能源行业一直难以保持竞争力。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境友好的解决方案，以帮助萎靡不振的加拿大石油业。

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.****
