Definition
Meaning and Definition
A technique to extract oil or natural gas from underground rock formations by injecting high-pressure fluid to create fractures.
The industrial process, often called fracking, involving drilling and injecting fluid (water, sand, chemicals) under high pressure to fracture shale rocks and release hydrocarbons; also refers to the associated technology, industry, and environmental debates.
Dialectal Variation
British vs American Usage
Differences
No major difference in definition. 'Hydraulic fracturing' is the formal term in both. The abbreviation 'fracking' (or 'fracing' in some industry writing) is equally common in both varieties. Regional differences exist in public and political discourse due to varying levels of industry presence.
Connotations
In the UK, the term is strongly associated with environmental protests and political controversy, with limited commercial application. In the US, it has stronger associations with energy independence, economic booms in regions like Pennsylvania and Texas, and a more polarized public debate.
Frequency
Higher frequency in American English due to the scale of the industry. In British English, it appears frequently in environmental and political reporting but less in general business contexts.

FAQ
Frequently Asked Questions
Yes, 'fracking' is the common abbreviation for 'hydraulic fracturing'. It carries the same technical meaning but is more prevalent in public and media discourse, often with stronger connotations.
Controversies centre on potential environmental impacts, including groundwater contamination, induced seismicity (earthquakes), high water usage, methane emissions, and the disposal of chemical-laden wastewater.
Yes, the basic principle is also used in geothermal energy projects to create fractures in hot rock, and sometimes in groundwater well enhancement, though the latter is less common.
The first experimental use was in 1947, and it became commercially widespread in the 1970s for conventional wells. Its combination with horizontal drilling for shale formations led to a major boom in the 2000s, which is when it entered widespread public awareness.
