What is flaring?

Flaring, in the context of oil and gas operations, refers to the controlled burning of natural gas that is associated with oil extraction. Here's a breakdown of what that means:

• Why it happens:
  • Often, natural gas is found alongside crude oil deposits. When oil is extracted, this associated gas comes up to the surface as well.
  • In situations where there isn't infrastructure to capture, process, and transport this gas (like pipelines), or when it's not economically viable to do so, it's often burned off.
  • Flaring is also used for safety reasons, to relieve pressure in equipment and prevent dangerous gas releases.
• The process:
  • The gas is directed through a pipe to a flare stack, where it's ignited and burned.
  • This results in the visible flame that's characteristic of flaring.
• Environmental impact:
  • While flaring converts methane (a potent greenhouse gas) into carbon dioxide (a less potent, but still significant, greenhouse gas), it still contributes to climate change.
  • It also releases other pollutants, including:
    • Nitrogen oxides
    • Sulfur dioxide
    • Particulate matter
• Key considerations:
  • There are efforts to reduce flaring worldwide, both to minimize environmental impact and to utilize the valuable natural gas that's being wasted.
  • There are different types of flaring, routine flaring, and non routine flaring. Routine flaring is done during normal operations, and non routine flaring is done during emergencies, or upsets in the system.

In essence, flaring is a method of disposing of excess natural gas, but it has significant environmental consequences.
