Thermal Recovery of Oil and Bitumen Roger M. Butler

, underground, devoid of mining—thermal recovery of bitumen and heavy oil: steam injection and combustion. If successful, a commercial project would begin in 2014 with expected production in 2016. Understanding how crude oil biodegrades into methane, or natural gas, opens the door to being able to recover the clean-burning methane directly from deeply buried, or in situ, oil sands deposits, says Steve Larter, U of C petroleum geologist in the The oil sands industry would no longer have to use costly and polluting thermal, or heat-based, processes (such as injecting steam into reservoirs) to loosen the tar-like bitumen so it flows into wells and can be pumped to the surface. Loading a truck, it will take 2 to 4 shovel 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). Pairs of parallel horizontal wells, one for steam and one for production, make it possible to recover bitumen continuously from oil sands. Baytex plans a pilot study in 2013. Patent #: Gaseous and solvent additives for steam injection for thermal recovery of bitumen from tar sands. This distinguishes in situ recovery from surface mining, which requires removing topsoil and other overburden and Another common form of thermal recovery is cyclic steam stimulation (CSS). Vast stretches of Canada's boreal forests cover a mixture of clay, sand, water, and bitumen – a heavy, black viscous oil. There are currently two primary different types of processes for in situ—i. 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. Regulatory approval has been received for the construction and operation of a two-stage bitumen recovery scheme using steam-assisted gravity drainage. Method of in-situ recovery of viscous oils or bitumen utilizing a thermal recovery fluid and carbon dioxide. Jaques – California heavy oil from thermal recovery is bad, unsustainable and is as well prohibited by the same legislation for use by the US government Mr. Baytex's current asset portfolio includes thermal recovery projects at Seal in the Peace River Oil Sands and at Kerrobert in southwest Saskatchewan. In situ oil sands production means extracting bitumen from underground by drilling wells into the reservoir, as with conventional oil and natural gas production. To even access these deposits, the forest must first be drained of its water, and then clear D.
