Description of Technology

          Natural gas trapped in underground oil deposits is one of the major issues faced by the oil and gas industry. When an oil well is drilled, confined natural gas must be released before pumping oil from the well. A common way to deal with the natural gas is by flaring it off, or burning, it. Flaring off natural gas is not only bad for the environment, but is also a loss of profit for the oil company.

          FlareNitro is a technology that captures natural gas trapped in oil deposits. Liquid nitrogen charges a reaction vessel that the material flows through to cool and liquefy the natural gas. The natural gas can then be pumped onto a tanker truck and transported. This process creates a second revenue stream for oil companies that is usually wasted and is more environmentally friendly than flaring off the natural gas. Other technologies capture the trapped natural gas, but those methods are usually expensive and only worth implementing when there is a high production rate of natural gas. FlareNitro’s less expensive approach makes it usable for wells with lower production rates.


          FlareNitro can be used in many oil drilling projects all over the world because the process is done at the well site. It is also less expensive than many other similar technologies, making it more applicable to small sites with lower production rates.

Features & Benefits

  • Captures an otherwise wasted resource in a way that is less expensive than similar methods.

  • Better for the environment than flaring off natural gas

  • Usable for wells that have lower production rates
