Petroleum exploration and development activity in western Canada has undergone a major revival in recent years as the result of significant advances in drilling and completion technology. Many formations that have large oil-in-place reserves in low permeability reservoir rocks, such as the Mississippian-age Pekisko Formation in Alberta, are being re-examined for their potential to be developed using "state-of-the-art" horizontal drilling and multi-stage hydraulic fracturing. These resource plays require a thorough understanding of the stratigraphy and sedimentology of the formation and detailed reservoir characterization in order to be economically successful. The proposed project will contribute to the development of Pekisko resource plays by investigating the formation in the Hawk Hills and Swan Hills areas in Alberta. The project is a partnership with ARC Resources Ltd. in Calgary, Alberta. A multi-disciplinary approach will be used which includes (1) characterizing and interpreting the sedimentation pattern of the carbonate platform deposits, (2) describing the post-depositional features and interpreting their sequence of formation, (3) using geochemical techniques to assess the influence of biological processes, paleotemperature and rock-water interactions on post-depositional alteration, and (4) evaluating the factors that control porosity and permeability in reservoir rocks. The results of the project will help refine geological models for the evolution of the vast Pekisko carbonate platform and for the origin of Mississippian petroleum reservoir rocks. These results may be used by ARC Resources and other companies to more effectively and economically develop their resource plays in the Pekisko Formation. New exploration and development activities will have a positive effect for Canada through job creation and economic growth. The project will help to address the trend of decreasing numbers of geoscientists working in the Canadian petroleum industry by providing career-related training of highly qualified personnel.

近年来，由于钻井和完井技术的重大进步，加拿大西部的石油勘探和开发活动经历了重大复苏。 许多在低渗透性储层岩石中拥有大量石油地质储量的地层，例如阿尔伯塔省密西西比时代的 Pekisko 地层，正在重新审查其利用“最先进”水平钻井和多级水力压裂进行开发的潜力。 这些资源区需要对地层的地层学和沉积学以及详细的储层特征有透彻的了解，才能在经济上取得成功。 拟议项目将通过调查艾伯塔省 Hawk Hills 和 Swan Hills 地区的地层，为 Pekisko 资源区的开发做出贡献。 该项目是与艾伯塔省卡尔加里的 ARC Resources Ltd. 合作的。 将使用多学科方法，包括（1）表征和解释碳酸盐台地沉积物的沉积模式，（2）描述沉积后特征并解释其形成顺序，（3）使用地球化学技术评估生物过程、古温度和岩水相互作用对沉积后蚀变的影响，以及（4）评估控制沉积后孔隙度和渗透率的因素。 储层岩石。 该项目的结果将有助于完善巨大佩基斯科碳酸盐台地演化和密西西比石油储层岩石起源的地质模型。 ARC Resources 和其他公司可以利用这些结果更有效、更经济地开发其 Pekisko 地层的资源区。 新的勘探和开发活动将通过创造就业和经济增长对加拿大产生积极影响。 该项目将通过为高素质人员提供与职业相关的培训，帮助解决加拿大石油行业地球科学家数量减少的趋势。
