Thermal Recovery of Oil and Bitumen Roger M. Butler

, underground, devoid of mining—thermal recovery of bitumen and heavy oil: steam injection and combustion. To even access these deposits, the forest must first be drained of its water, and then clear D. There are currently two primary different types of processes for in situ—i. Grizzly's independent engineering firm, GLJ Petroleum Consultants, estimated the Thickwood Thermal Project will ultimately recover approximately 107 million barrels of bitumen in their report dated December 31, 2011. 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. Jaques – California heavy oil from thermal recovery is bad, unsustainable and is as well prohibited by the same legislation for use by the US government Mr. Ivanhoe Energy's goals for the initial wells in Pungarayacu were to add to its preliminary understanding of the reservoir, to carry out thermal recovery tests, and to extract heavy oil for characterization and upgrading tests using its proprietary HTL upgrading process. SAGD recovery involves drilling pairs of horizontal wells, one placed above the other in each pair. Steam is Another drilling technology being discussed is also a form of thermal recovery called cyclic steam stimulation (CSS). Ivanhoe Energy The crude gravity is similar to Athabasca bitumen, at approximately 8° API, however other characteristics are quite different and present specific upgrading challenges. 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. Trinidad and Tobago High Commission in Canada exploring Drilling Operations for Heavy Oil Resource. 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. SAGD extracts bitumen from underground by drilling wells into the reservoir, as with conventional oil and natural gas production. Raising the temperature of the host formation reduces the oil and bitumen viscosity, and, in environmental remediation, increases vapour pressure. Vast stretches of Canada's boreal forests cover a mixture of clay, sand, water, and bitumen – a heavy, black viscous oil.
