The unprecedented rapid growth of hydrocarbon production from shales over the last decade has resulting in a paradigm shift in the energy sector that has immediate and long term global implications. This growth in production has, however, markedly outpaced our understanding of geological processes that determine reservoir properties, how to measure these properties, how to predict and design for optimum development of the resource, and how to recognize and mitigate environmental impact of development. The proposed research will address these issues, and in particular, develop predictive models of hydrocarbon source and reservoir quality based on detailed geological and engineering studies that will include lithological, petrophysical and geomechanical analyses of major gas and oil producing shales. The research includes development of better methods of reservoir characterisation, establishment of important effective stress laws for fine grained strata and understanding impact of geomechanical stratigraphic on hydraulic fracturing. Engineering aspects and environmental consequences of hydraulic fracturing will be explored including chemistry of flow back water. The research involves integration of field studies of ancient strata, laboratory analyses, experiments, and numerical modeling. The proposed research will involve collaboration with industry, university colleagues and government agencies and provides the opportunity for training of highly qualified personnel in a field in which there is currently a critical shortage.

过去十年，页岩碳氢化合物产量空前快速增长，导致能源部门发生了具有直接和长期全球影响的范式转变。然而，产量的增长速度远远超过了我们对决定储集层性质的地质过程、如何测量这些性质、如何预测和设计资源的最佳开发以及如何认识和减轻开发对环境的影响的理解。拟议的研究将解决这些问题，特别是在详细的地质和工程研究的基础上开发碳氢化合物来源和储集层质量的预测模型，这些研究将包括对主要产气和产油页岩的岩性、岩石物理和地质力学分析。研究内容包括开发更好的储层特征描述方法，建立细粒岩层的重要有效应力定律，以及了解地质力学地层对水力压裂的影响。将探讨水力压裂的工程方面和环境后果，包括回流水的化学作用。这项研究综合了对古地层的实地考察、实验室分析、实验和数值模拟。拟议的研究将涉及与工业界、大学同事和政府机构的合作，并为培训目前严重短缺的领域中的高素质人员提供机会。
