Curtailing Direct Emissions Services
In 2013, flaring of associated gas generated approximately 30% of our greenhouse gas emissions. In addition, our job is to produce energy, but we also use energy to do that. Because our energy use accounts for a large share of our greenhouse gas emissions and has a cost, it is important that we reduce it. We have a dual imperative: reducing our greenhouse gas emissions, notably by halving flaring between 2005 and 2014, and commoditizing a valuable energy source wherever possible.
Reducing the Flaring of Associated Gas
The Basics
Oil production is usually accompanied by the production of "associated gas".
Associated gas is often recovered as an energy source used directly by the production facilities or monetized (sold).
However, it is sometimes necessary to burn the gas in purpose-designed units called flares, particularly in the following cases:
- For safety reasons, gas can be flared to relief pressure on the system quickly in case of emergency or during maintenance. That`s why a a surveillance device allows flares, in case of problem or of excess, to fire the evacuated gas instantly. Without the flare and the flame, a hazardous gas build-up could occur.
- During specific, non-routine operations, such as well tests or start-ups of new installations, the gas is flared until gas with the required properties (for transportation or re-use) is obtained.
- Where, for technical or financial reasons, the gas cannot be commoditized. This has historically been the case when the volume and/or quality of the gas has not justified investing in infrastructure allowing it to be used locally or transported. It is this latter category of continuous flaring — which represents the largest quantity — that is the priority focus of our efforts today.
