Previous studies of the lower Palaeozoic in the Eagle Plain & Richardson Mountain area of north-west mainland Canada in the Yukon & Northwest Territories have dealt either with outcrop or surface sections, or with subsurface well sections, but did not integrate these data. This has led to the development of inconsistent stratigraphic nomenclatures and an inability to form a consistent sequence stratigraphic model for the lower Palaeozoic in this area. This bulletin presents a stratigraphic synthesis based on data from surface exposures in the mountains surrounding Eagle Plain and on subsurface borehole data from beneath Eagle Plain and from the interior plain bordering the east flank of the Richardson Mountains. An internally consistent stratigraphic framework is developed, including reaffirmation of some previous nomenclature, restriction to certain areas of others, and definition of new stratigraphic units. The positions of carbonate-to-shale transitions which commonly exert a strong control on structural evolution and on the occurrence of sedimentary mineral deposits & hydrocarbons are more accurately delineated. A detailed sedimentological analysis of the Ogilvie Formation, the most prospective lower Palaeozoic unit for the occurrence of hydrocarbon reservoirs, is also included, along with a map of thermal maturity at the top of the unit.

Natural gas, especially unconventional gas, has an increasingly important role in meeting the world's energy needs. Experts estimate that it has the potential to add anywhere from 60-250% to the global proven gas reserve in the next two decades. To maintain pace with increasing global demand, Unconventional Gas Reservoirs provides the necessary bridge into the newer processes, approaches and designs to help identify these more uncommon reservoirs available and how to maximize its unconventional potential. Loaded with reservoir development and characterization strategies, this book will show you how to: - Recognize the challenges and opportunities surrounding unconventional gas reservoirs - Distinguish among the various types of unconventional reservoirs, such as shale gas, coalbed methane, and tight gas formations - Drill down and quantify the reservoir's economic potential and other critical considerations - Gain practical insights and tools to efficiently identify, appraise, and develop unconventional gas reservoirs - Understand various techniques used to analyze reservoir parameters and performance as well as how they were applied to numerous real-world case studies - Upgrade to the latest information on perspectives and insights with discussion of key differences used for today's unconventional gas characterization versus original conventional methods that failed in the past

Sediment Provenance: Influences on Compositional Change from Source to Sink provides a thorough and inclusive overview that features data-based case studies on a broad range of dynamic aspects in sedimentary rock structure and deposition. Provenance data plays a critical role in a number of aspects of sedimentary rocks, including the assessment of palaeogeographic reconstructions, the constraints of lateral displacements in orogens, the characterization of crust which is no longer exposed, the mapping of depositional systems, sub-surface correlation, and in predicting reservoir quality. The provenance of fine-grained sediments—on a global scale—has been used to monitor crustal evolution, and sediment transport is paramount in considering restoration techniques for both watershed and river restoration. Transport is responsible for erosion, bank undercutting, sandbar formation, aggradation, gullying, and plugging, as well as bed form migration and generation of primary sedimentary structures. Additionally, the quest for reservoir quality in contemporary hydrocarbon exploration and extraction necessitates a deliberate focus on diagenesis. This book addresses all of these challenges and arms geoscientists with an all-in-one reference to sedimentary rocks, from source to deposition. - Provides the latest data available on various aspects of sedimentary rocks from their source to deposition - Features case studies throughout that illustrate new data and critical analyses of published data by some of the world's most pre-eminent sedimentologists - Includes more than 150 illustrations, photos, figures, and diagrams that underscore key concepts
