Genalta Power and Shell Canada have agreed to build a produced-gas-to-power plant that will make use of the gas associated with Shell's bitumen production in an effort to reduce gas flaring at its Peace River oil sands leases. "Once developed, thermal The petroleum and natural gas company also noted it received regulatory approval to construct a two-stage bitumen recovery scheme using steam-assisted gravity drainage. Numerical modeling of biodegradation and most importantly our “know-how” are some of the tools that we utilize at Gushor to predict fluid properties and distribution of oil quality , de-convolute oil mixtures, allocate production, and monitor thermal recovery operations for heavy oil and bitumen accumulations, among other applications for the characterization of biodegraded petroleum systems. 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. A summary report of the study, conducted by Jacobs Consultancy, was publicly released on May 16, 2012 and provides insight for sustainable oil sands development in Alberta. 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 pilot will use three parallel horizontal wells with electrical cables to conduct heat throughout the targeted bitumen formation. 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. Geosolutions for Unconventional Systems & Heavy Oil Recovery. The onset that the 'tar sands' classification is scientifically incorrect , as he explains that “[tar sands] terminology should be avoided because oil sands are neither tar nor sands…tar is not a raw material; instead, it is a residual product that remains after severe thermal cracking of heavy oil”. This apparently paradoxical situation is occurring because supplies of conventional crude oil have peaked while growing economies in South America have increased demand for refined fuel. Facilities on its Peace River oil sands leases: the Cliffdale Battery, which uses cold or primary recovery methods, and the Peace River Complex which uses thermal or enhanced oil recovery techniques to extract bitumen from underground. Thermal Projects Wabiskaw - Recognized the potential for cost-effective thermal recovery of a 2.0 billion barrel bitumen deposit in the Grand Rapids Formation within the Woodenhouse area. Can oil sands/heavy oil/bitumen be mined or recovered through steam injection in an environmentally sustainable way that does not compromise valuable freshwater supplies? The company noted the acquisition adds an approved steam-assisted gravity drainage project to its asset portfolio, which currently includes thermal recovery projects at Seal in Peace River oil sands and at Kerrobert in southwest Saskatchewan. 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). 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.
