Robust Methane Reduction Campaigns for Strengthened Greenhouse Gas Management

Methane is one of the E&P products with a Global Warming Potential about 25 times greater than carbon dioxide, any company that is able to reduce the methane emissions will gain environmental benefits and strengthen its reputation. For PTTEP, it has annually disclosed its greenhouse gas (GHG) emission performances to relevant parties. In 2016 the direct emissions disclosed were 4.6 million tonnesCO
₂
e, of which about 5% were contributed by methane. PTTEP had initiated the methane survey campaigns for emphasizing the emission reduction. The campaign used an infrared camera and a high volume sampler for effectively identifying and quantifying the emission volumes, which in 2016 about 11,000 tonnesCO
₂
e per year were detected. PTTEP has adopted the results for improving the GHG performance reporting. Normally, the methane emissions were obtained from a calculation; thus, with the survey results PTTEP was able to improve the methane emission performances by 60%.
