EOR is the extraction of additional oil from fully developed fields, using a variety of methods beyond conventional waterflooding or gas injection, to maintain reservoir pressure. Laricina Energy points out in a presentation, Strategies for Cheaper Bitumen, the rate of oil recovery is a function of the (time averaged) reservoir temperature and that the optimal recovery temperature is in the range of 150oC. Is the THAI™ system (below) or any other process that comes along for economically recovering heavy oil and bitumen the answer to our dependence on oil for the majority of our transportation fuels? Steam is Another drilling technology being discussed is also a form of thermal recovery called cyclic steam stimulation (CSS). Trinidad and Tobago High Commission in Canada exploring Drilling Operations for Heavy Oil Resource. 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. SAGD recovery involves drilling pairs of horizontal wells, one placed above the other in each pair. (How much oil is lost in the burning process? This does not appear to be pie in the sky, as they The heat generated in the reservoir reduces the viscosity of the heavy oil, allowing it to drain into a second, horizontal well from where it rises to the surface. As they note the trade off the thermal inertia of the oceans. 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. SAGD extracts bitumen from underground by drilling wells into the reservoir, as with conventional oil and natural gas production. With today's technology there are roughly 170 billion barrels of oil to be recovered in the tar sands, and an additional 1.63 trillion barrels worth underground if every last bit of bitumen could be separated from sand. It will take a millennium to bring the atmosphere, the shallow waters and deeper ocean waters into thermal equilibrium on account of all of the energy the oceans have already stored. It won't add any more to GHG emission than other sources of Oil, or indeed actually less, IF AND ONLY IF they use Nuclear Electricity, Nuclear Steam & Process Heat and Nuclear Hydrogen to extract & refine the bitumen. I used to work on SAGD and other thermal recovery processes to recover heavy oil and bitumen from heavy oil and oil sand reservoirs in Alberta and Saskatchewan, Canada.
