Operators have implemented a wide range of methods to improve these operating efficiencies, applying improved technologies, heat recycling equipment, and solvent assisted recovery. Than 20% with conventional techniques, Dhinsa says . In this article, I will look briefly at what the oil sands are, how Heat, pressure, and the activity of bacteria transformed the carbohydrates into hydrocarbons, and crude oil was formed. There are approximately 2.5 trillion barrels of the stuff, the largest on figuring out how to get the dirtiest possible oil out of the hardest-to-reach places. The University of Alberta, Canada, has inked an option agreement with Strata Oil & Gas Inc. For the exclusive Canadian license to its technology to extract bitumen from fractured carbonates. Albertans have always known that in the northern part of their province, there are vast deposits of bitumen--black, tarlike goo that is mixed with sand, clay, water and oil. Shell, for instance, is working on a "novel thermal recovery process"--embedding large electric heaters in the deposits and literally cooking the earth. A project's steam to oil ratio (SOR) measures the amount of steam that is required to be injected so as to produce one barrel of bitumen. Before we delve into various environmental issues including the social impact of the oil sands development, it is important to understand the properties of oil sands and how bitumen is recovered using different technologies. In situ projects heat steam to high temperature to inject into bitumen reservoirs that are too deep to mine. The technology can be implemented using established equipment and extraction materials while allowing for recycling of material and reduced thermal treatment.
