Liquid nitrogen (LN 2) is considered as one of the potential water-free fracturing fluids. Due to its unique low-temperature characteristics, severe thermal stress will be created in the rock under down-hole conditions during the LN 2 fracturing process. As a result, not only several primary fractures, but also secondary cracks perpendicular …Web

Liquid nitrogen is very cold! At normal atmospheric pressure, nitrogen is a liquid between 63 K and 77.2 K (-346°F and -320.44°F). Over this temperature range, liquid nitrogen looks much like boiling water. Below 63 K, it freezes into solid nitrogen. Because liquid nitrogen in a usual setting is boiling, its usual temperature is 77 K.Web

Cryogenic liquids are liquefied gases that are kept in their liquid state at very low temperatures (i.e. boiling points below -150°C). For example, liquid nitrogen is inert, colourless, odourless, non-corrosive, and non-flammable liquid with a boiling point at -195.8°C at atmospheric pressure. It has a similar appearance to water.Web
