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. Operators have implemented a wide range of methods to improve these operating efficiencies, applying improved technologies, heat recycling equipment, and solvent assisted recovery. 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. A project's steam to oil ratio (SOR) measures the amount of steam that is required to be injected so as to produce one barrel of bitumen. GLJ identified 1.8 billion barrels of exploitable bitumen in place and has assigned 824 million barrels of contingent resource as a best estimate using steam assisted gravity drainage and Grizzly's ARMS development model. The pilot will use three parallel horizontal wells with electrical cables to conduct heat throughout the targeted bitumen formation. 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. April 19, 2013 - Reducing fresh water use and enhancing oil recovery in oil sands development are among five new pilot projects supported by Alberta's The project is designed to develop the bitumen in a reservoir that is too viscous for conventional production, but does not require as much heat as most current thermal projects. GLJ's development profile of Grizzly Oil Sands ULC is a private, Calgary-based oil sands exploration and production company focusing primarily on the development of oil sands resources using thermal recovery methods. Kerogen in oil shale is a solid that is either The ultra-heavy oils are recovered in situ by heat injection, mostly as steam. 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. For example, this layout is taken from the application of 100% recovery, but EROEI may be less than SAGD. Baytex plans a pilot study in 2013. Baytex's current asset portfolio includes thermal recovery projects at Seal in the Peace River Oil Sands and at Kerrobert in southwest Saskatchewan. If successful, a commercial project would begin in 2014 with expected production in 2016. 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%. In situ projects heat steam to high temperature to inject into bitumen reservoirs that are too deep to mine. Solid tar sand bitumen is mined and liquified in surface plants. Regulatory approval has been received for the construction and operation of a two-stage bitumen recovery scheme using steam-assisted gravity drainage.
