Shale are findable in areas where organic material deposited under anoxic conditions, so that bacterias had not the chance to dissolve the organic matter. Most probably are paleo restricted basins, or even continental shelfs and lakes.

Marcellus Shale is named after the town of Marcellus in New York, where the rock formation was first described. It is a type of sedimentary rock that is rich in natural gas and is an important source of natural gas in the United States.
The Marcellus Shale was first discovered by geologists in 1839 in Marcellus, New York. The potential of the formation as a natural gas resource was later recognized, leading to its development as a major source of natural gas in the United States.
A sedimentary rock containing methane is known as shale. Shale is a fine-grained sedimentary rock formed from the accumulation of mud and clay with organic matter that can produce and store methane gas within its pores.
Pittsburgh, Pennsylvania is home to the largest natural gas field in the US, known as the Marcellus Shale field.

It can be. It is found in a rock type called shale and is produced in the shale form the original bio mater included in the deposition of the shale. If a unit of shale lithology is to be found on the continental shelf strata then it is likely that that shale will contain shale gas and it will be under the sea.
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
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.
No. Shale is not fuel in and of itself. However, some shale deposits have oil or natural gas trapped in pore spaces. This can be processed into fuel.

Natural gas extracted from shale rock could become a significant global energy source.
Shale is a sedimentary rock that is generally formed as particles of sediment settle out in calm water. Shale can be formed in shallow inland waters or deep ocean basins. Shale rock is generally high in organic content. Once covered up by other sediments and buried over millions of years, heat and pressure begin to work on these sediments and oil and gas are formed. Some of the oil and gas may begin to migrate upwards, to layers of sandstone and porous limestone where it becomes trapped. These are considered conventional oil and gas reservoirs and shale is often the "source rock" or original source of the hydrocarbons. Natural gas and oil that occur in shale are called "unconventional". Now with new horizontal drilling and hydraulic fracturing methods it is possible to extract that oil and gas. "Unconventional" gas is quickly becoming the new norm. We have over 100 years worth (and growing) of natural gas supply in North America. In a nutshell, shale gas is standard natural gas buried much deeper and complex to extract.

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.
