Oil Sands And Heavy Oils

Companion to 'Oil and Natural gas resources of Canada, 1976'. Describes resources at Lloydminster, Cold Lake, Athabasca, Peace River, Wabasca and Buffalo Head, including recovery technologies and estimates of recoverable oil.

Reservoir characterization requires integration of engineering, geology, and geophysics, with rock physics supplying a key link. In this volume, geophysical methods, especially time-lapse 3D seismic, are emphasized, and a range of enhanced oil-recovery methods (EOR) are discussed, showing the need to accurately describe a reservoir before and after production.

When it comes to future reliable oil supplies, Canada¿s oil sands will likely account for a greater share of U.S. oil imports. In 2008 oil sands accounted for 46% of Canada¿s total oil production and oil sands production is increasing as conventional oil production declines. Since 2004, when a substantial portion of Canada¿s oil sands were deemed economic, Canada has ranked second behind Saudi Arabia in oil reserves. As oil sands production in Canada is predicted to increase to 2.8 million barrels per day by 2015, environ. issues are a cause for concern. Contents of this report: (1) Intro.; (2) World Oil Sands Reserves and Resources: What Are Oil Sands?; U.S. and Canada Oil Sand Resources; (3) History of Development. Charts and tables.

Heavy oils, extra-heavy oils and tar sands are major players for the future of energy.They represent a massive world resource, at least the size of conventional oils. They are found all over the world but Canada and Venezuela together account, by themselves, for more than half of world deposits. They share the same origin as the lighter conventional oils, but their geological fate drove them into thick, viscous tar-like crude oils. Most of them result from alteration processes mediated by microbial degradation. They are characterized by a low content of lighter cuts and a high content of impurities such as sulfur and nitrogen compounds and metals ; so, their production is difficult and deployment of specific processes is required in order to enhance their transportability and to upgrade them into valuable products meeting market needs, and honouring environmental requirements.Although these resources are increasingly becoming commercially producible, less than 1% of total heavy crude oil deposits worldwide are under active development. The voluntarily wide scope of this volume encompasses geology, production, transportation, upgrading, economics and environmental issues of heavy oils. It does not pretend to be exhaustive, but to provide an authoritative view of this very important energy resource.
