Oil sands, including the Athabasca Oil Sands in northern Alberta, are the second largest hydrocarbon resrouce on earth. In the last decade, engineering technology has evolved that can now economically produce the bitumen resource in the oil sands. This volume showcases the geology of oil sands from aroudn the world. It highlights the Athabasca Oil Sands of northern Alberta and the geochemistry of the associated bitumen resources, but points directionally for the development of other oil-sands deposits in the world. A novle feature is the 'case study' approach. Although much of the perspective is sedimentological and/or stratigraphic, the substance of the book should find wide appeal to Earth scientists working in all geoscience domains. The papers, from authors employed in the industry, academic researchers, and government scientists, provide new updates and insights into the regional geology, nuances of detailed depositional systems, reservior modeling, and emerging sustainability issues.
