Question: Genie Energy and which other oil and gas company, considered one of the seven 'Supermajor' oil companies, owns American Shale Oil, the developers of in-situ shale oil extraction technology in Rifle, Colorado?
Context: The Union process was an above ground shale oil extraction technology for production of shale oil, a type of synthetic crude oil.  The process used a vertical retort where heating causes decomposition of oil shale into shale oil, oil shale gas and spent residue.  The particularity of this process is that oil shale in the retort moves from the bottom upward to the top, countercurrent to the descending hot gases, by a mechanism known as a rock pump.  The process technology was invented by the American oil company Unocal Corporation in late 1940s and was developed through several decades.  The largest oil shale retort ever built was the Union B type retort. The American Shale Oil, LLC (AMSO), originally known as EGL Oil Shale, LLC, was a developer of in-situ shale oil extraction technology based in Rifle, Colorado.  It was owned by Genie Energy and Total S.A..  In May 2016, Genie Energy announced that the AMSO project was closing. Spent shale or spent oil shale (also known as retorted shale) is a solid residue from the shale oil extraction process of producing synthetic shale oil from oil shale.  It consists of inorganic compounds (minerals) and remaining organic matter known as char—a carbonaceous residue formed from kerogen.  Depending on the extraction process and the amount of remaining organic matter, spent shale may be classified as oil shale coke, semi-coke or coke-ash residue, known also as oil shale ash.  According to the European Union waste list all these types of spent shale are classified as hazardous waste. The Nevada–Texas–Utah retort process (also known as NTU, Dundas–Howes or Rexco process) was an above-ground shale oil extraction technology to produce shale oil, a type of synthetic crude oil.  It heated oil shale in a sealed vessel (retort) causing its decomposition into shale oil, oil shale gas and spent residue.  The process was developed in the 1920s and used for shale oil production in the United States and in Australia.  The process was simple to operate; however, it was ceased from the operation because of a small capacity and labor extensiveness. Tight oil (also known as shale oil, shale-hosted oil or light tight oil, abbreviated LTO) is light crude oil contained in petroleum-bearing formations of low permeability, often shale or tight sandstone.  Economic production from tight oil formations requires the same hydraulic fracturing and often uses the same horizontal well technology used in the production of shale gas.  While sometimes called "shale oil", tight oil should not be confused with oil shale, which is shale rich in kerogen, or shale oil, which is oil produced from oil shales.  Therefore, the International Energy Agency recommends using the term "light tight oil" for oil produced from shales or other very low permeability formations, while the World Energy Resources 2013 report by the World Energy Council uses the terms "tight oil" and "shale-hosted oil". The Galoter process (also known as TSK, UTT, or SHC; its newest modifications are called Enefit and Petroter) is a shale oil extraction technology for a production of shale oil, a type of synthetic crude oil.  In this process, the oil shale is decomposed into shale oil, oil shale gas, and spent residue.  A decomposition is caused by mixing raw oil shale with a hot oil shale ash, generated by combustion of carbonaceous residue (semi-coke) in the spent residue.  The process was developed in 1950s and it is used commercially for the shale oil production in Estonia.  There are projects for further development of this technology and for expansion of its usage, e.g. in Jordan and USA. Total S.A. (] ; or ) is a French multinational integrated oil and gas company and one of the seven "Supermajor" oil companies in the world.  Its businesses cover the entire oil and gas chain, from crude oil and natural gas exploration and production to power generation, transportation, refining, petroleum product marketing, and international crude oil and product trading. The Superior multimineral process (also known as the McDowell–Wellman process or circular grate process) is an above ground shale oil extraction technology designed for production of shale oil, a type of synthetic crude oil.  The process heats oil shale in a sealed horizontal segmented vessel (retort) causing its decomposition into shale oil, oil shale gas and spent residue.  The particularities of this process is a recovery of saline minerals from the oil shale, and a doughnut-shape of the retort.  The process is suitable for processing of mineral-rich oil shales, such as in the Piceance Basin.  It has a relatively high reliability and high oil yield.  The technology was developed by the American oil company Superior Oil. Oil shale reserves refers to oil shale resources that are economically recoverable under current economic conditions and technological abilities.  Oil shale deposits range from small presently economically unrecoverable to large potentially recoverable resources.  Defining oil shale reserves is difficult, as the chemical composition of different oil shales, as well as their kerogen content and extraction technologies, vary significantly.  The economic feasibility of shale oil extraction is highly dependent on the price of conventional oil; if the price of crude oil per barrel is less than the production price per barrel of shale oil, it is uneconomic. Mountain West Energy, LLC is an American unconventional oil recovery technology research and development company based in Orem, Utah.  It is a developer of the In-situ Vapor Extraction Technology, an "in-situ" shale oil extraction technology.  The company owns 880 acre oil shale leases in the Uintah Basin, Uintah County, Utah.
