Origin and reservoir characteristics of gas shales and coalbed methane

我正在进行的研究的目的是确定影响沉积岩中有机质的分布、丰度和组成的因素，以及富有机层（煤层气和页岩气）中天然气储存和生产的潜力。 我的研究计划整合和应用新的实验室和分析方法，并研究最近的有机丰富的矿床，以解释古老的地层。 在接下来的五年里，我正在进行的研究计划的总体主题将继续，但将进一步结合地质力学研究，我们认识到，非常规气藏的储气和流动特性与岩石的力学地层学密切相关。在接下来的五年里，我的研究计划将包括：1）实验室研究将量化压力，温度，应力和应变对成岩作用，结构，渗透率和扩散速率以及有机质和泥岩中气体储存的影响。2）正在进行的黑色页岩沉积学研究将扩大到包括天然气页岩资源的评估以及影响温室气体和其他气体（即烟道气，硫化氢和硫氧化物）的气体容量，含量和封存潜力的因素。3）页岩和煤的有机成熟。 将继续记录和解释加拿大西部盆地的有机成熟水平。 本研究旨在利用成熟度数据和数值模型更好地了解地层的构造史和热史以及油气生成史。4）将对气页岩和煤的地质力学性质进行调查，以了解页岩和煤的组构、成分和力学性质以及渗透性和/或扩散性之间的相互关系。 这些研究将调查矿物学、组构和孔隙结构与不同有效应力的储层特征之间的复杂相互作用。 这项工作的部分目标是将岩石地层学与地层的机械地层学结合起来。

The objective of my ongoing research is to establish factors that affect the distribution, abundance and composition of organic matter in sedimentary rocks and the potential for  storage and production of gas in organic rich strata (coalbed methane and gas shales).  My research program integrates and applies novel experimental laboratory and analytical methodologies and study of recent organic rich deposits to the interpretation of ancient strata.   During the next five years the overall theme of my ongoing research program will continue but will further incorporate geomechanical studies with our recognition that the gas storage and flow properties of unconventional gas reservoirs is closely linked to the mechanical stratigraphy of the rocks. During the next five years my research program will comprise:1) experimental laboratory studies will quantify the effects of pressure, temperature, stress and strain on diagenesis, fabric, permeability and diffusion rates and storage of gas in organic matter and mudrocks.2) ongoing studies of  the sedimentology of black shales will expand to include evaluation of gas shale resources and those factors that effect gas capacity, content and sequestration potential for greenhouse and other gases (i.e. flue gas, hydrogen sulphide and oxides of sulphur).3)organic maturation of shales and coals.  Documenting and interpreting the levels of organic maturation in Western Canadian Basin will be continued.  This research is directed toward using maturation data and numerical models to better understand the tectonic and thermal history of strata and oil/gas generative history.4)investigation of the geomechanical properties of gas shales and coals will be undertaken in order to understand the interrelationship between shale and coal fabric, composition and mechanical properties and permeability and/diffusion.  These studies will investigate the complex interplay between mineralogy, fabric and pore structure and reservoir characteristics with varying effective stress.  Part of the goal of this work in to marry the lithostratigraphy with mechanical stratigraphy of the strata.
