The global economy is driven by energy. With increasing attention being focused on the negative environmental effects of coal burning, liquid and gaseous hydrocarbons are becoming the principal source for our ever-growing energy needs. For producers this requires maintaining the current volume of hydrocarbon production, which in turn requires replacing production with new reserves. Presently, however, the new "elephant" fields (i.e. those capable of high-volume conventional oil and gas production) occur in deep-marine turbidite systems situated in very deep water, commonly more than 2500 m, off modern continental margins, like the eastern and northern coasts of Canada. In these areas exploration and production costs are prohibitive, and as a consequence necessitates careful economic consideration and concern. In order to make these exploration and exploitation efforts economic, companies must increase their chance of success and the volumetric output from each well. The variable that most impacts these economically significant parameters is the geological framework and how it controls reservoir occurrence and performance. A detailed understanding of reservoir architecture and performance, however, requires an understanding of sub-seismic-scale features, which therefore requires field-based outcrop and experimental investigation. Based on the Neoproterozoic Windermere Supergroup, part of this research will study the facies composition and stratal geometry of a deep-marine basin floor to slope siliciclastic succession. In addition, a companion experimental program will investigate the influence of sediment concentration on the characteristics of deposition from the very flows that build-up the deep-marine sedimentary record.

全球经济是由能源驱动的。随着越来越多的注意力集中在燃煤燃烧的负面环境影响上，液体和气态烃已成为我们不断增长的能源需求的主要来源。对于生产商而言，这需要维持当前的碳氢化合物生产量，这又需要用新的储量代替生产。然而，目前，新的“大象”田（即能够高量的传统石油和天然气生产的象征）发生在位于非常深水的深海洋浊度系统中，通常超过2500 m，超过2500 m，在现代大陆边缘，例如加拿大东部和北部海岸。在这些领域，勘探和生产成本是过于刺激的，因此需要仔细的经济考虑和关注。为了进行这些探索和剥削工作，经济，公司必须增加成功的机会和每个井的体积产出。影响这些具有经济意义的参数的最大变量是地质框架以及它如何控制储层的发生和性能。然而，对储层架构和性能的详细理解需要对次要尺度的特征有了解，因此需要基于现场的露头和实验研究。基于新元古代温德米尔超级组，这项研究的一部分将研究深海盆底层的相的组成和层层几何形状，以倾斜硅质碎屑替代。此外，伴侣实验计划将研究沉积物浓度对沉积物特征的影响，从而积累了深陆沉积物记录。
