Shale oil extraction

Shale oil extraction is an industrial process for unconventional oil production. This process converts kerogen in oil shale into shale oil by pyrolysis, hydrogenation, or thermal dissolution. The resultant shale oil is used as fuel oil or upgraded to meet refinery feedstock specifications by adding hydrogen and removing sulfur and nitrogen impurities. Shale oil extraction is usually performed above ground (ex situ processing) by mining the oil shaShale oil processing is defined as an industrial process to which raw shale oil is subjected to extract oil from it—basically a process to produce unconventional oil Oil Shale Processing an overview ScienceDirect Topics

Oil shale Definition, Composition, Extraction, Production, & Facts

Oil shale, any sedimentary rock containing various amounts of solid organic material that yields petroleum products, along with a variety of solid by-products, when subjected to pyrolysis—a treatment that consists of heating the rock to above 300 °C (about 575 °F) in the absence of oxygen. The.Permeability of oil shale changes as it undergoes heating and compression [14,15]. The permeability-time curves for columns of conﬁned fragments prepared from different grades of Green River oil shales show that as compressive strain increases with time, the columns’ pore geometry, porosity, and permeability undergo Advancements and Environmental Implications in Oil Shale

The Products Formation and Flow During Underground Thermal

Shale is sedimentary rock formed by the accumulation of pelagic sediments, minerals and their further transformation. The pyrolysis of oil shale can yield liquid hydrocarbons and a combustible gas that can be used as energy sources. There are various methods of oil shale thermal processing. However, methods that do not require The above review demonstrates that by oil shale pyrolysis, the extraction of oil and gas through the pores and fractures formed by thermal cracking and kerogen pyrolysis can be realized without the need to crush the rock into small ore blocks artificially. 3.

Subcritical Water Extraction of Huadian Oil Shale at 300 °C

In this work, Huadian oil shale was extracted by subcritical water at 300 °C over different time periods to better characterize the underground mining of oil shale in situ. The results revealed that the kerogen in the oil shale mostly transformed into bitumen through extraction over a long time period by subcritical water at 300 °C; however, a 1975. 36. Abstract Oil-shale deposits at El-lajjun, a rich oil-shale area south of Jordan, were extracted with organic solvents.
