What is fracking? 


Best insight from top research papers

Fracking, or hydraulic fracturing, is a process used to increase the flow of oil or natural gas from low permeability rock formations such as shale. It involves pumping a mixture of water, proppants, and chemicals into the rock at high pressure, creating fractures that extend outward from the well bore. These fractures are held open by the proppants, allowing oil and gas to flow from the rock to the production well . Fracking is commonly used in combination with horizontal drilling to access natural vertical fractures in the shale, turning otherwise unproductive formations into major oil and gas fields . The process has been used in the United States since the 1940s and is essential for the economic recovery of hydrocarbons from unconventional reservoirs . However, the use of chemicals in fracking has raised environmental and public health concerns, leading to ongoing debates and legal battles .

What is Petroleum?4 answersPetroleum is a complex mixture of hydrocarbons found in various forms such as gas, liquid, and solid. It consists mainly of organic carbon and hydrogen compounds, with additional elements like nitrogen, sulfur, and oxygen, as well as traces of metals. This fossil fuel is utilized for various purposes, including as a major energy source for fuels, heating, and more, constituting a significant portion of the global energy supply. The physical properties and chemical compositions of petroleum are influenced by the organic matter in the source rock where it is generated, with processes like migration and remobilization affecting its composition in reservoirs. Despite its long history of use, efforts to standardize petroleum terminology have only emerged in recent decades to enhance understanding of its composition and properties.
What is petroleum?5 answersPetroleum is a naturally occurring complex mixture of hydrocarbons, organic compounds, and metals. It is a carbon-based fossil fuel that can exist in gaseous, liquid, or solid forms. Crude oil is the most common form of petroleum, which is obtained by drilling wells beneath the Earth's surface. It is composed of various hydrocarbon components with different chemical natures, including paraffin, cycloparaffinic, and aromatic hydrocarbons. Petroleum products derived from crude oil, such as gasoline, kerosene, and lubricating oils, are widely used as fuels and oil products. The composition and properties of petroleum are influenced by factors such as the type of organic matter in the source rock, generation in the source rock, migration to the reservoir, and possible subsequent alteration and migration in the reservoir.
Whate is shale oil reservoir3 answersShale oil reservoirs refer to the underground formations of shale rocks that contain liquid hydrocarbons, such as oil and gas. Shale, which is a type of sedimentary rock, can act as both a source and a reservoir for hydrocarbons. It is formed from the accumulation of organic-rich mud and clay particles over millions of years. Shale oil reservoirs are characterized by their tight storage space, low porosity, and ultra-low permeability, which make it difficult for the hydrocarbons to flow freely. As a result, hydraulic fracturing (fracking) is often required to extract the oil and gas from these reservoirs. The evaluation of shale oil reservoirs involves assessing factors such as organic matter content, mineral composition, porosity, and permeability.
Can extraction of natural gas through fracking be carbon neutral?5 answersFracking using CO2 instead of water has been proven to be technically feasible and environmentally friendly, making it a promising alternative approach for shale gas and oil withdrawal. CO2 fracturing technology has several advantages, such as low damage and easy flowback, making it suitable for complex rock strata with low pressure, low permeability, and strong water sensitivity. Additionally, CO2 fracturing can stimulate unconventional reservoirs more effectively than conventional hydraulic fracturing, making it a viable option for reservoir stimulation and reconstruction in the future. Furthermore, the extraction of natural gas through fracking can be carbon neutral if the technology replaces rather than adds to the consumption of dirtier fossil fuels. The potential for greenhouse gas reduction through sequestration of CO2 and avoidance of methane leakage from the natural gas system is also quantified.
What is coal?5 answersCoal is a complex and diverse material that is a familiar substance and an important natural resource. It has close links with peat, which can be considered a precursor, and also with other fossil fuels such as petroleum and natural gas. Coal represents the largest fraction of the resources and reserves among the readily available energy sources. It is a heterogeneous material composed of organic and inorganic constituents, with inorganic ingredients in the form of minerals and organo-bound inorganic elements. These elements have an impact on technological parameters, the environment, human health, and recycling processes. Coal is a readily combustible sedimentary rock primarily composed of carbon, along with variable quantities of other elements such as nitrogen, oxygen, and sulfur. It is formed from ancient vegetation and consolidated between other rock strata to form coal seams. The properties of coal, such as rank, type, and grade, are determined by its origin and burial history.
What is fossil fuels?4 answersFossil fuels are natural fuels formed from the remains of living organisms in the geological past. They can exist in solid, liquid, or gas form. Coal is a solid fossil fuel consisting mainly of carbonized plant matter and is used as fuel. Fossil fuels, such as coal, petroleum, shale oil, tar sands, and natural gas, contain hydrogen and carbon that react with oxygen to release energy. The combustion of fossil fuels poses major threats to the environment, including land damage, smog, acid rain, and changes in the atmosphere's composition. Fossil fuels release carbon dioxide into the atmosphere, contributing to global warming. Fossil fuels are complex compounds of carbon, hydrogen, oxygen, sulfur, and nitrogen, along with mineral matter and moisture. Hydrocarbon fuels, including petroleum-based fuels, coal, natural gas, and oil shale, are sources of fossil fuels.
