OIL & GAS TECHNICAL TERMS GLOSSARY
If you are looking for a definition of any technical terms in oil & gas field, then this site is yours.
Until now, we've collected around 2000 technical terms, but if this still not enough, and you've found any term that is not in our database, please contact us, and we will happily find it for you, or you can just check it again later, because every unsuccessful search will be recorded by our system for later update.
Thanks and happy searching ^^.
Search Result for Fracture
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.
fracture pressure
The pressure at which a formation will break down, or fracture.
fracture gradient
The pressure gradient (psi/ft) at which the formation accepts whole fluid from the wellbore.
matrix acidizing
The procedure by which acid flow is confined to the natural permeability and porosity of the formation. Compare fracture acidizing.
inhibited acid
An acid that has been chemically treated before the acidizing or acid fracturing of a well to lessen its corrosive effect on the tubular goods and yet maintain its effectiveness. See acid fracture, acidize.
formation competency test
A test used to determine the amount of pressure required to cause a formation to fracture.
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that is carried in suspension by the fracturing fluid and that serves to keep the cracks open when fracturing fluid is withdrawn after a fracture treatment.
formation fracture pressure
The point at which a formation will crack from pressure in the wellbore.
fracture acidizing
A procedure by which acid is forced into a formation under pressure high enough to cause the formation to crack. The acid acts on certain kinds of rocks, usually carbonates, to increase the permeability of the formation. Compare matrix acidizing.
nitro shooting
A formation-stimulation process first used about a hundred years ago in Pennsylvania. Nitroglycerine is placed in a well and exploded to fracture the rock. Sand and gravel or cement is usually placed above the explosive charge to improve the efficiency of the shot. Nitro shooting has been largely replaced by formation fracturing.
