integrated assessment UK Shale resource

项目摘要

Shale gas has the potential to transform the UK's future energy security. With imports currently accounting for 50% of its domestic gas requirements, projected to rise to roughly 80% by 2035, the big question is 'Are there enough shale gas resources to effectively replace the declining North Sea and Irish Sea gas production, and for how long?' The largest unknown is the potential gas reserves (i.e. recoverable resources) that would be commercially viable to be produced in the UK. There have been a number of differing in-place estimates for the Upper Bowland Shale in the northern England Carboniferous, ranging from 164-447 tcf suggested by Andrews (2013), to 8-19 tcf quoted by Uguna et al. (2017). In the absence of flow test data, reliable recoverable reserves estimates could not have been published. There has been a single well test carried out by Cuadrilla in Lancashire, the results of which have not yet been made public. The industry, the scientific community, the government, and environmental scientists, have been starved of modern borehole electric log, core and well test data with which to assess both resource potential and the associated environmental impact. This is about to change, with drilling planned to take place during the course of the proposed study in Cheshire, Lancashire, North Yorkshire, and North Nottinghamshire. This research project will focus on the Carboniferous (Bowland Shale) basins of the East Midlands, Lancashire, Cheshire, and Yorkshire. The vision is of a multidisciplinary approach to solving problems in the main research focus areas set out in Challenge 2 of the NERC call. We will bring together key researchers from several institutions around the UK, working on UK shale science from the micro-pore (<10 nm) to the basin scale. Key aspects of shale mineralogy, petrology, geochemistry, stratigraphy, rock mechanics, gas generation and adsorption and fluid flow in low porosity rocks will be combined into a holistic basin-scale model to generate a better scientifically-grounded set of estimates. Key sensitivities related to input parameters will be tested, and more importantly, compared/contrasted with available production data from the planned wells . The outcome of this 4-year project will be a more scientifically defendable assessment of the location and magnitude of UK shale resources, guided by an improved understanding of the shale properties and fluid flow through the shale, before, during and following hydraulic fracturing to ascertain whether shale gas has the potential to have a marked impact on energy security in the UK for several decades into the future. This project will critically inform the key stakeholders (Government, Industry, Academia, and the general public) of UK shale potential, and will provide input to discussions on future UK energy strategy. Collaboration with those projects funded within the other Challenges in this programme will allow us to assess whether or not this resource can be accessed in a commercially viable and environmentally responsible way.ReferencesAndrews, I.J. 2013.

页岩气有可能改变英国的未来能源安全。目前，进口量占其国内天然气需求的50％，预计到2035年将上升到约80％，最大的问题是“是否有足够的页岩气资源有效地取代北海和爱尔兰海气的下降，以及多长时间？”最大的未知是潜在的天然气储量（即可回收资源），这些资源将在英国生产在商业上可行。英格兰北部石炭纪的上鲍兰页岩有许多不同的地面估计值，范围从Andrews（2013）建议的164-447 TCF到Uguna等人的8-19 TCF。（2017）。在没有流程数据数据的情况下，可靠的可回收储量估计不可公开。库德里拉（Cuadrilla）在兰开夏郡（Lancashire）进行了一次井测试，其结果尚未公开。该行业，科学界，政府和环境科学家已经饿死了现代钻孔电气原木，核心和井测试数据，以评估资源潜力和相关的环境影响。这将要改变，计划在柴郡，兰开夏郡，北约克郡和北诺丁汉郡的拟议研究过程中进行钻探。该研究项目将集中于东米德兰兹，兰开夏郡，柴郡和约克郡的石炭纪（鲍兰页岩）盆地。该愿景是在NERC呼叫挑战2中规定的主要研究重点领域中解决问题的多学科方法。我们将汇集来自英国多个机构的主要研究人员，从事英国页岩科学从微孔（<10 nm）到盆地量表。页岩矿物学，岩石学，地球化学，地层，岩石力学，气体产生和吸附以及低孔隙岩石中的流体流的关键方面将结合成整体盆地尺度模型，以产生更好的科学基础估计值。将测试与输入参数相关的关键敏感性，更重要的是，与计划中的井中的可用生产数据进行了比较/对比。这项为期四年项目的结果将是对英国页岩资源位置和大小的更科学捍卫的评估，在对页岩特性和流体流过页岩的了解中，在液压液压破裂之前，之后和之后的液态破裂，以确定页岩气是否有可能对英国的能源安全产生明显的影响。该项目将严重告知英国页岩潜力的主要利益相关者（政府，行业，学术界和公众），并将为关于未来英国能源战略的讨论提供意见。与本计划其他挑战中资助的项目合作将使我们能够评估该资源是否可以以商业上可行且对环境负责的方式访问。 2013年。石炭纪的鲍兰页岩：地质和资源估计。英国能源与气候变化部的地质调查局，伦敦，英国，C。 2017年9月17日至22日在意大利佛罗伦萨举行的第28届国际有机地球化学会议。
