The rock in question is oil shale, from which aspirin, nylon, and perfume can be obtained as by-products through a process called retorting. Oil shale is heated to release kerogen, a precursor to oil, which can then be further processed to produce various products including aspirin, nylon, and perfume.
A bendable rock is a type of sedimentary rock called shale. Shale is composed of fine grains and is more prone to bending or breaking under pressure compared to other types of rocks. It is commonly used in construction and as a source of oil and natural gas.
Chainman Shale is a type of sedimentary rock that was formed from the accumulation of mud and silt in a marine environment. It is known for its characteristic gray to black color and its importance in providing insights into ancient environments and climates.

A material that contains hard-to-mine petroleum is oil shale. Oil shale is a sedimentary rock that contains kerogen, a solid organic material that can be converted into synthetic crude oil through processes like pyrolysis. Extracting petroleum from oil shale is more challenging and costly compared to conventional oil extraction due to the need for extensive heating and processing. As a result, while it represents a significant potential resource, its economic viability often depends on oil prices and technological advancements.
Oil shale is a type of rock that contains kerogen, a precursor to oil. When heated, the kerogen in oil shale can be converted into oil and gas. This process is known as pyrolysis.
Shale is a sedimentary rock that is structured in thin layers, like pages in a book. The oil is trapped between these "pages". Since the oil can't flow between the layers it only can be extracted at the broken edges of the shale deposit or by breaking the shale ip into tiny bits and washing the oil off for collection.

That would be "Oil shale" - shale is a kind of rock. Anyway, the oil shale is dug up and then hot, hot steam or other substance is run through it to make the oil runny enough to flow down and out, where it is then collected.
They are locked in shale rock.
Oil shale is a type of rock that contains a substance called kerogen, which can be converted into oil through a heating process called retorting. It is a potential unconventional source of oil, but extracting oil from oil shale can be expensive and environmentally challenging due to the energy-intensive process and potential environmental impacts.
The mining of oil shale requires conversion of the solid hydrocarbons in the rock to liquid form, so that they can pumped or processed.This is done by heating the rock to a high temperature, and separating and collecting of the resultant liquid. This heating process is called retorting.
Shale can be dissolved by using acidizing techniques, where acid is pumped into the shale reservoir to dissolve the rock and create channels for increased oil and gas flow. Hydraulic fracturing, or fracking, is another method where high-pressure fluids are injected into the shale to create fractures and release trapped oil and gas. These techniques are commonly used in the oil and gas industry to extract resources from shale formations.
Shale underneath, to provide the organic material, then the oil and gas are usually found within sandstone. Above you will find shale again, or possibly caly or slate
