Understanding few Types of Explosion occuring in Oilfield

An explosion is a type of fire but one which combusts with such a rapid force that it causes an effect known as overpressure (explosion). Under certain conditions,
the speed of the front of the flame may move to a supersonic level, resulting in a significantly more powerful explosion.

There are three types of explosions that are associated with the oil and gas industry. These are:

Boiling Liquid Expanding Vapour Explosion (BLEVE)
Confined Vapour Cloud Explosion (CVCE)
Unconfined Vapour Cloud Explosion (UVCE)
