Thermal Recovery of Oil and Bitumen Roger M. Butler

Crude oil is currently a primary source of energy globally, but the decline of light oil reserves has shifted attention to large deposits of untapped heavy oil and bitumen energy resources (~70 % of the World’s 9-13trillion barrel oil resource). Baytex's current asset portfolio includes thermal recovery projects at Seal in the Peace River Oil Sands and at Kerrobert in southwest Saskatchewan. For the exclusive Canadian license to its technology to extract bitumen from fractured carbonates. If successful, a commercial project would begin in 2014 with expected production in 2016. Baytex plans a pilot study in 2013. 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. 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. 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. Than 20% with conventional techniques, Dhinsa says . 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. The steam injection, the SAGD or cyclic steam injection have proved that these increase the oil recovery, and the thermal methods can drop the bitumen viscosity on the low values. Regulatory approval has been received for the construction and operation of a two-stage bitumen recovery scheme using steam-assisted gravity drainage. For example, this layout is taken from the application of 100% recovery, but EROEI may be less than SAGD. During the process of oil extraction from oil sands, bitumen, a semi-solid oxidized form of oil, is removed using thermal recovery techniques that consume about 3.1 barrels of water per single barrel of oil 1.
