Note : Excludes savings with less than 1 kt CO₂ e. The IEA estimates of Canadian oil and gas methane emissions (58,600 kt CO₂e) are 67.5 per cent higher than emissions reported in the 2022 NIR. Install new devices, in order of cost, includes vapor recovery units, blowdown capture, flares, and plunger lifts. Leak detection and repair (LDAR) includes upstream and downstream. Replace existing devices, in order of cost, includes early replacement of devices (high-bleed for low-bleed), replace pneumatic pumps with electric pumps, replace compressor seals or rods, replace pumps and controllers with instrument air systems, and replacing gas pneumatic devices with electric. Other includes methane-reducing catalysts, use of associated gas in remote locations, better maintenance practices, and “green” well completions.
