How shale can be dissolved?

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.


What is found on top of coal slate or shale?

== == == == == == The cap rock on a coal bed is usually a sedimentary rock, (i.e. shale sandstone etc.) but not always shale. Slate is a metamorphic rock, usually derived from shale that has been exposed to high pressures and temperatures over very long periods of time. Ways to tell the difference between slate and shale: Slate will have a smooth surface, and possible have light glare at a right angle. Shale will have a dull, sandy surface. Tap them against something hard. Slate will make a "clink" noise, almost like porcelain or ceramic, where shale will make a "thud" sound. Rub it against your teeth. Slate will be smooth, shale will be gritty. == == == ==


Is an wedge shattering a slab of shale a physical or chemical change?

The wedge shattering the slab of shale is a physical change. This is because the shale undergoes a change in shape and size without any new substances being formed.


What is a rock that yields oil when heated?

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.


What happens when oil shale burns?

When oil shale burns, it releases heat and produces carbon dioxide, water vapor, and other combustion byproducts. The heat generated can be harnessed for energy production through combustion or other thermal processes. Burning oil shale can also emit pollutants and greenhouse gases, which can have environmental and health impacts.
