When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants (either sand or aluminium oxide) hold the fractures open. Hydraulic fracturing began as an experiment in 1947, and the first commercially successful application followed in 1950.
Hydraulic fracturing was first used to recover natural gas and oil in 1947. Halliburton was the first company to use it commercially in 1949.
