Gazprom confesses to several big methane leaks this year
bne IntelliNews
Russia’s gas giant Gazprom has admitted to several
large methane leaks this year, the company said. Methane is one of the most environmentally harmful gases.
Gazprom has taken responsibility for the leaks from its pipelines that include one of 2.7mn cubic metres on June
4 due to an emergency pipeline shutdown in Tatarstan, the biggest methane leak in two years. That has roughly the same short-term planet-warming impact of 40,000 internal combustion engined cars driving for a year, according to the Environmental Defence Fund.
Gazprom said the gas was released after it detected a problem with its Urengoy-Centre 1 pipeline in Russia's Tatarstan region. The company said that “given the urgency”, it wasn’t able
to use a mobile compressor station to reduce the methane released by the repairs, though it claimed still to have cut
22% of potential emissions.
The company also admitted to several smaller leaks around planned pipeline maintenance. The climate warming effect of methane is judged to be 86-times more powerful than carbon dioxide.
The satellite detected another giant methane plume on May 24 with an estimated emissions rate of 214 tonnes per hour. Gazprom said this leak had resulted from two days of planned maintenance on the Urengoy-Petrovsk pipeline in Russia's Bashkortostan region. The emissions amounted to about 900,000 cubic metres, it said, which the company described as “in line with the industrial safety regulations.”
The leaks were detected by a new international satellite capable of detecting emissions from individual sites. The same satellite uncovered similarly large methane leaks earlier
this year from gas pipelines in Turkmenistan, another major gas producer.
A satellite reportedly looked down on central Turkmenistan in early February and detected methane leaks from at least eight natural gas pipelines and unlit flares in the Galkynysh gas field, releasing as much as 10,000 kilograms per hour of the supercharged greenhouse gas (GHG).

Russian gas company Gazprom admitted to releasing 1,800 tonnes of methane into the atmosphere this year, in the biggest leakage in two years and the equivalent of driving 40,000 cars around for a year.
That amount of methane would have a planet-warming impact equivalent to driving 250,000 cars around in circles for a similar amount of time.
Turkmenistan was also caught with leaky pipelines in 2019 and has remained a headache in the global fight against climate change.
Gazprom, along with most of Russia’s blue chip companies, has been striving to improve its environmental, social and governance (ESG) scores; however, analysts say while the leaks are a smudge on its reputation the leak is unlikely
to cause much damage to its business or stock price, even though the company will incur a fine in line with Russia’s environmental regulations.
“While gas companies generally score better on environmental issues than do oil companies, they are still closely watched
by activists as producers of hydrocarbons,” analysts with BCS GM said in a note. “The issue here for Gazprom is twofold.
“The leak has roughly the same short-term planet-warming impact of 40,000 internal combustion engined cars driving for a year”
First, methane is a very powerful – if relatively short-lived
– greenhouse gas. Second, ESG (environmental, social and governance) issues have become a key investment screen for institutional investors, especially for funds based in Europe, while methane emissions by the oil & gas industry have come under increased scrutiny by environmentalists worried about global warming. In the end, this particular event will prove transitory for Gazprom, but we would expect the company
to boost maintenance capex at least somewhat in the coming years to address pipeline leaks.”
Under Russian regulations, methane is a pollutant; hence its release into the atmosphere is regulated. Every gas
