Extracting oil from oil shale using internal distillation (in situ retorting)

Abstract The method of internal distillation (in situ retorting) and internal treatment for extracting shale oil is one of the modern methods developed with good economic quality but at a higher cost. Therefore, the net of fossil oil can be considered alternative energy. Hydrocarbon-rich hydrogen turns into oily shale, which distills by heat and turns into gases and petroleum liquids suitable for use as fuel. The fumes from burning oil shale are considered cancer-causing, so advanced treatment is required before extraction. As the temperature increases, the speed of oil extraction increases dramatically, but at 510°C, the production rate begins to decline. Oil extraction produces more than gas; the highest production peak is around 550 h. The permeability is closely proportional to the oil producers, and the permeability is inversely proportional to the highest temperature in the case of high heat through the combustion of coal with oxygen internally. The type of oil shale is affected by the surrounding environment and the temperature of the earth’s crust.
