Which breaks the rock into small fragments. 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. We would have had the best oil reservoir in the world sitting right here.” As it is, the resource is heavy. In the middle of a keynote address to an audience of geologists, seismic specialists and heavy oil executives, he paused to make a wistful appeal. A CNOOC limited offshore project, and Sunshine Oilsands' research of the 'multi-component thermal fluid thermal recovery technology' gives a possible indication that it could work economically in bitumen reservoirs,” co-chairman Songning Shen said in a press release. A tiny Canadian oilsands company has struck a deal with a subsidiary of China's state-owned oil corporation, agreeing to trade information on oilsands technology and potential exploration efforts. All emissions are used in the process and are injected into the bitumen.” As Nikipelo tells the story, when he took his original concept to the Alberta Research Council, Dr. The successful projects were Imperial Oil is proposing an alternative to thermal recovery processes to reduce direct greenhouse gas emissions from production by more than 90%. As they note the trade off the thermal inertia of the oceans. 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. 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). 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. It describes a method of thermal bitumen recovery called wedge wells. 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. Alberta's Innovative Energy Technologies Program (IETP) is supporting 5 new pilot projects to reduce energy use, water use and CO2 emissions in oil sands processing as well as improving the recovery of crude oil and bitumen in reserves that were once unrecoverable.
