Fracking - Simple English Wikipedia the free encyclopedia

The first use of hydraulic ,fracturing, to extract ,substances, from rock was in 1947. The modern ,fracturing, technique, called 'horizontal slickwater ,fracturing,', was first used in 1998. It made the extraction of shale gas economically practical. The energy from the injection of a highly pressurized ,fluid, creates new channels in the rock.
