Fracking Technology

Fracking Technology was first invented in 1947, but the modern Fracking technique has made the extraction of Shale Oil and Natural Gas economically feasible.
The modern Fracking technique for Natural Gas was first done in 1998, at the Barnett Shale formation in Texas and for Shale and Tight Oil it was done in 2008, at the Bakken Shale formation in North Dakota.

Fracking (Hydraulic Fracturing) in combination with Horizontal Drilling (Directional Drilling) is used for the extraction and revovery of unconventional Natural Gas, Shale Oil and Light Tight Oil, within Shale and Tight Rock formations.

Fracking is done by pumping fracking fluid into a wellbore at a rate sufficient to increase pressure downhole to exceed that of the fracture gradient of the rock and a fracture is formed. The rock cracks and the fracking fluid continues farther into the rock, extending the crack still farther, and so on. To keep this fracture open after the injection stops, a solid proppant, commonly a sieved round sand, is added to the fluid. The propped fracture is permeabile enough to allow the flow of formation fluids to the well.
