Hydraulic ,fracturing, in the United Kingdom started in the late 1970s with ,fracturing, of the conventional ,oil, and gas fields near the North Sea.It has been used in about 200 British onshore ,oil, and gas wells since the early 1980s. [1] The technique did not attract attention until licences use were awarded for onshore shale gas exploration in 2008. [2] [3]

The SAGD process of heavy ,oil, or bitumen production is an enhancement on the steam injection ,techniques, originally developed to produce heavy ,oil, from the Kern River ,Oil Field, of California. The key to all steam flooding processes is to deliver heat to the producing formation to reduce the viscosity of the heavy ,oil, and enable it to move toward the producing well.
