Thermal Recovery of Oil and Bitumen Roger M. Butler

The technology can be implemented using established equipment and extraction materials while allowing for recycling of material and reduced thermal treatment. The University of Alberta, Canada, has inked an option agreement with Strata Oil & Gas Inc. However, the random nature of the carbonate bed, which is neither uniform nor consistent, makes economical bitumen recovery a technological challenge. Regulatory approval has been received for the construction and operation of a two-stage bitumen recovery scheme using steam-assisted gravity drainage. ET Energy's Electro Thermal technology could be used to pump out 600 billion barrels of Alberta's oil sands bitumen. If successful, a commercial project would begin in 2014 with expected production in 2016. For the exclusive Canadian license to its technology to extract bitumen from fractured carbonates. Than 20% with conventional techniques, Dhinsa says . 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). Baytex's current asset portfolio includes thermal recovery projects at Seal in the Peace River Oil Sands and at Kerrobert in southwest Saskatchewan. Baytex plans a pilot study in 2013. In situ oil sands production means extracting bitumen from underground by drilling wells into the reservoir, as with conventional oil and natural gas production. Typically several sets of wells are laid out beside each other to provide an interaction between the wells and heat the intervening oil so that it can be recovered. Also, the reader should note that the hydrocarbon being obtained in the Alberta tar sands is "bitumen" which must be converted to a lower viscosity "oil" to be pumped in a pipeline and then refined. For example, this layout is taken from the application of 100% recovery, but EROEI may be less than SAGD.
