Do American oil refineries process shale oil?
Output from American shale oil fields has pushed U.S. crude production to all-time highs. Most American refineries are configured to process heavier crude grades, creating a mismatch with the growing supply of light shale oil being extracted in places like the Permian Basin in Texas.
Which process is involved conventional oil shale production?
The most common method of extracting shale oil is by surface mining. The in situ combustion process is used for extracting shale oil from far below the surface. The extracted shale oil then undergoes pyrolysis at 842 to 932°F (450 to 500°C) to produce oil shale (synthetic crude oil), shale gas and residue (solid).
How is shale oil made?
Shale oil is an unconventional oil produced from oil shale rock fragments by pyrolysis, hydrogenation, or thermal dissolution. These processes convert the organic matter within the rock (kerogen) into synthetic oil and gas.
What is the difference between shale oil and oil shale?
Oil shale is different than shale oil in that oil shale is essentially rock that contains a compound called kerogen, which is used to make oil. Shale oil refers to hydrocarbons that are trapped in formations of shale rock.
Who owns U.S. oil refineries?
Largest petroleum refineries in the United States
| Rank | Refinery | Owner |

How is shale oil transported?
Shale oil is primarily transported via pipeline, utilizing existing and new pipeline infrastructure.
What is the biggest oil refinery in the US?

How is shale oil processed?
The processing of shale oil is essentially done by retorting, which consists of heating crushed shale in a closed vessel up to a temperature (~ 500 °C) at which the matter releases crude oil, gases, char, and steam. The fraction of extractable oil is 10–20% by volume with respect to the solid shale material.
How does shale oil affect refinery economics?
The characteristics of shale oil impact refinery economics While shale oil composition varies from basin to basin throughout the United States, some of its common characteristics can lead to significant disruptions across the refining supply chain – from transportation from the production site to shipment from the refinery.
How long does it take for shale gas to decompose?
The ratio of oil shale gas to shale oil generally increases along with retorting temperatures. For a modern in situ process, which might take several months of heating, decomposition may be conducted at temperatures as low as 250 °C (480 °F).
How to convert kerogen in oil shale to shale oil?
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.
