GHG Emission Performance

MEG has taken measures to achieve one of the lowest GHG emissions intensities in the thermal heavy oil industry.
Between 2013 and 2018, our net greenhouse gas (GHG) emissions intensity reduced by 9% and in 2018 was more than 20% below the industry average. This outcome was achieved through a committed investment in energy efficiency through the application of cogeneration and innovative reservoir advancements including eMSAGP and eMVAPEX.

This approach has reduced emissions intensity while also minimizing financial impacts and helping us align with increasingly stringent carbon regulations.

Reducing GHGs with eMSAGP & eMVAPEX

When approximately one-third of the oil from a well has been recovered and the reservoir has been heated, MEG’s patented, proprietary enhanced Modified Steam and Gas Push (eMSAGP) technology can be introduced. eMSAGP involves injecting a non-condensable gas, like natural gas, into the reservoir to reduce the steam injection rate by approximately 50%, resulting in steam-oil ratios in the range of 1 to 1.25.

By applying the eMSAGP process to significant portions of the operation, MEG has achieved an average SOR of 2.19 in 2018 at its Christina Lake Project compared to the in situ industry average of 3.1.

Recently, MEG has further reduced the SOR through advanced solvent injection technology by piloting enhanced Modified VAPour Extraction (eMVAPEX). This proprietary technology, if proven successful, will further enhance our growth potential while minimizing GHG emissions, even beyond those from eMSAGP. MEG has been granted funding from Alberta Innovates, Natural Resources Canada, Emissions Reductions Alberta, and Sustainable Development Technology Canada for continued eMVAPEX work.

We will continue to explore additional recovery advancements that can further reduce our environmental impacts and improve performance.

 

Air Quality

MEG uses natural gas to generate steam used for bitumen production.

Nitrogen oxides (NOx as NO2 equivalent) and sulphur dioxide (SO2) are by-products of the natural gas combustion process which have the potential to affect air quality.

MEG regularly tracks air emissions and reports results both internally and externally. We use a variety of methods to monitor air quality, including continuous emission monitoring systems (CEMS), ambient monitoring, and stack testing among others to ensure limits and standards are met.
