Thermal Recovery of Oil and Bitumen Roger M. Butler

(How much oil is lost in the burning process? 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. Which breaks the rock into small fragments. The 1800-bpd Saleski pilot began production in 2011 and is considered the world's first carbonate project using thermal horizontal well recovery for bitumen. 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. Taking just those that relate to oil sand production roughly 70% plan on using thermal methods to recover deeper oil (mainly SAGD, though there are small amounts of THAI, cyclic steam and electrothermal). 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? 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. These fragments (with waste rock largely removed) are then mixed with hot water and pumped to large tanks at the primary upgrader, where the sand, water, and bitumen are separated. 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.
