Thermal Recovery of Oil and Bitumen Roger M. Butler
Publisher:

For example, this layout is taken from the application of 100% recovery, but EROEI may be less than SAGD. 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. Energy conservation and non-thermal production. 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). 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. Bitumen extraction and froth treatment. The pilot will use three parallel horizontal wells with electrical cables to conduct heat throughout the targeted bitumen formation. Raising the temperature of the host formation reduces the oil and bitumen viscosity, and, in environmental remediation, increases vapour pressure. "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. The objective of this book is to present to the reader the current methods of recovery for heavy oil and tar sand bitumen technology by nonthermal and thermal methods. Because of “reserve growth,” a country or a company may increase its oil reserves without tapping new areas if it can recover more oil from its known fields. 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. In situ oil sands production means extracting bitumen from underground by drilling wells into the reservoir, as with conventional oil and natural gas production. However, the random nature of the carbonate bed, which is neither uniform nor consistent, makes economical bitumen recovery a technological challenge. 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. Carbon capture, storage and sequestration. 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. 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. In the 1960s, introduction of thermal recovery technologies (application of steam technology) caused abrupt and substantial additions to reserves in fields that contain heavy oil (American Petroleum Institute (API) gravity less than .
