Flaring and venting

What is it? Where there’s oil, there’s gas, usually in large quantities. This associated gas (AG) is released when oil reservoirs are drilled and throughout oil extraction. Flaring is the controlled burning of AG; venting is the controlled release of unburned gases directly to the atmosphere. Why Does Flaring and Venting Happen? Most AG is re-injected back into the well; this can help to force out more oil. Having the facility to flare and vent AG is important in keeping wells safe during shut downs and emergencies. The decision to vent or flare will depend on local conditions and the nature of the gas. Flaring reduces methane emissions but venting
