FAQ
Frequently Asked Questions
Casinghead gas is a type of natural gas, specifically the kind that is produced alongside crude oil ('associated gas'). Not all natural gas is casinghead gas.
It is named for the 'casing head', which is the top of the well's casing (the large pipe lining the wellbore) where the gas is captured as it separates from the oil.
It can be processed to remove valuable liquids (NGLs), injected back into the reservoir to maintain pressure, used to power equipment, sold to a pipeline, or, unfortunately, flared (burned off) if no infrastructure exists to handle it.
Yes, economically and environmentally. It represents a significant energy resource. Flaring it wastes fuel and releases CO2, making its capture and use a key industry and environmental focus.
