Hydraulic fracturing Definition
An operation in which a specially blended liquid is pumped down a well and into a formation under pressure high enough to cause the formation to crack open, forming passages through which oil can flow into the wellbore. sand grains, aluminum pellets, glass beads, or similar materials are carried in suspension into the fractures. when the pressure is released at the surface, the fractures partially close on the proppants, leaving channels for oil to flow through to the well. compare explosive fracturing.

Formation fracturing
A method of stimulating production by opening new flow channels in the rock surrounding a production well. often call a frac job. under extremely high hydraulic pressure, a fluid (such as distillate, diesel fuel, crude oil, dilute hydrochloric acid, water, or kerosene) is pumped downward through production tubing or drill pipe and forced out below...
Propping agent
A granular substance (sand grains, aluminum pellets, or other material) that is carried in suspension by the fracturing fluid and that serves to keep the cracks open when fracturing fluid is withdrawn after a fracture treatment....
Explosive fracturing
When explosives are used to fracture a formation. at the moment of detonation, the explosion furnishes a source of high-pressure gas to force fluid into the formation. the rubble prevent fracture healing, making the use of proppants unnecessary. compare hydraulic fracturing....
Stimulation
Any process undertaken to enlarge old channels or to create new ones in the producing formation of a well (e.g., acidizing or formation fracturing)....
Fracturing
Application of hydraulic pressure to the reservoir formation to create fractures through which oil or gas may move to the well bore....
