/engineering/taxonomy/term/802/all en /engineering/article/methane-emissions-abandoned-oil-and-gas-wells-underestimated <p>A recent Æ»¹ûÒùÔº study published in Environmental Science and Technology finds that annual methane emissions from abandoned oil and gas (AOG) wells in Canada and the US have been greatly underestimated – by as much as 150% in Canada, and by 20% in the US. Indeed, the research suggests that methane gas emissions from AOG wells are currently the 10th and 11th largest sources of anthropogenic methane emission in the US and Canada, respectively.</p> Tue, 26 Jan 2021 21:06:05 +0000 Katherine Gombay 8513 at /engineering
