"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. Technology in the recovery of such reserves is advancing rapidly and suddenly this huge country with produced oil rates and reduced production costs. STEAM ASSISTED GRAVITY DRAINGE (SAGD) The most promising thermal recovery technology is the Steam Assisted Gravity Drainage (SAGD) process. Kerogen in oil shale is a solid that is either The ultra-heavy oils are recovered in situ by heat injection, mostly as steam. Alberta's vast oil sands — a mixture of sand, water and a semisolid form of petroleum called bitumen — account for 97 percent of Canada's proven crude oil reserves, making Canada the largest source of foreign oil for the world's According to a report by oil sands industry consulting firm Strategy West, “The primary disadvantage of steam-based thermal recovery techniques is the large amount of energy and water that must be consumed for the generation of steam. With some experts predicting peak oil as early as 2030, there is more and more interest in so called "unconventional resources" such as heavy oil and bitumen. Thermal recovery methods, as applied in heavy oil and oil sand deposits, and in environmental remediation, have the common objective of accelerating the hydrocarbon recovery process. 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. Raising the temperature of the host formation reduces the oil and bitumen viscosity, and, in environmental remediation, increases vapour pressure. 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. The 1800-bpd Saleski pilot began production in 2011 and is considered the world's first carbonate project using thermal horizontal well recovery for bitumen. 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). 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. EOR is the extraction of additional oil from fully developed fields, using a variety of methods beyond conventional waterflooding or gas injection, to maintain reservoir pressure. Solid tar sand bitumen is mined and liquified in surface plants. 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.
