Hydraulic fracturing or fracking is one of the methods to intensify the work of oil and gas wells and increase the injectivity of injection wells. The method consists in creating a highly conductive fracture in the target formation to ensure the flow of the produced fluid (gas, water, condensate, oil or a mixture thereof) to the bottom of the well.
After hydraulic fracturing, the well flow rate, as a rule, increases sharply. The method makes it possible to "revive" idle wells, where oil or gas production by traditional methods is no longer possible or unprofitable. In addition, the method is currently used to develop new oil reservoirs, the extraction of oil from which by traditional methods is unprofitable due to low production rates. It is also used for the extraction of shale gas and tight sand gas.
Typically, oil service companies specialize in hydraulic fracturing and other methods of intensifying oil production.
