Why does the gas have to be burned? Can it just be released? What is more polluting? The natural gas or the CO2?

Methane produces much more greenhouse warming than CO2. Also, releasing large amount of combustibles in a single place is asking for trouble, isn't it ?

Yes, I think it's just the controlled burning of flammable waste. This has been going on since the 19th century in oil fields all over the world so it cannot be out of concern for global warming.

The interesting thing is that natural gas used to just be a waste product until it became economical to recover it and use it for energy generation in its own right.

In many fieldsds, oil and gas can only be produced together. If you want the oil, you need to extract the associated gas alongside and, in places with no infrasturcture to collect that gas, it indeed has to be gotten rid of.

Flaring it is just the safest way to do it.

You have written about the difficulty and expense of LNG infrastructure, and pipelines are not cheap either.

So, until recently it wasn't just a matter of capturing it but of using it after capture.

Jerome, you say that the gas is often flared when there is no infrastructure to deal with it, but there must be infrastructure to handle the petroleum.  At today's energy prices is building the necessary infrastructure to utilize the gas really still too expensive?

The infrastructure for gas is completely different to that for oil, and needs to be invested into as a separate business decision, and that depends on how much gas there is. It's quite often the case that there is enough oil in a field to justify the exploitation and oil (with the requisite infrastructuree), but not enough gas to justify the parallel investment.

Oil infrastructure is generally simpler, and the contractual structure for oil a lot simpler than for gas. Plus, for a long time, there simply was no market for gas in many parts of the world. This is slowly changing.

For those reading Russian - here's a short article on problems with utilisation of gas in oil exploration. Easy enough, low internal gas prices is one of the reasons. As the gas prices are slated to increase, the burning is going to come down. Supply and demand in action.

Thanks for the link to the article. It was very interesting.

It is good that the domestic price of natural gas will rise. It appears from the article though that it's been a lack of coordination of supply and demand that has lead to 20% of Russian natural gas production being flared off. The author states that holding down the price for domestic consumption made it uneconomical to either process or transport the gas from its production site. Also, apparently there are accounting issues since the oil companies do not consider gas production costs as part of their already existing costs of production.

I wonder about the concluding paragraphs where the author states that the government has the authority to strip companies of their licenses if they fail to fully utilize the natural resources to which they have been granted access.  How likely a possibility do you consider that to be in reality?

Finally, I'd be interested in having your opinion on the following quote from a different article:

The Russian government has repeatedly pledged to reduce natural gas consumption in power generation and increase coal use, in order to maximize gas exports. Earlier this year, Russian President Vladimir Putin also suggested that coal be given a greater role. But this goal would require large-scale construction of coal-fired power generation facilities, totaling some 40 gigawatts by 2020.

Doesn't such a policy sacrifice the health of Russian citizens, given how polluting coal is, (or are there plans to install modern pollution control equipment as well?), and the health of the planet, due to increased CO2 output from replacing natural gas with coal, to the short term financial interests of the Russian state?

Have a look here. It doesn't seem that the forecast of huge additional coal generation is likely to happen.

Thanks.  I'll take a look at it.

if they would only make the choice to use it in this way.  The wastefulness is, well, convenient.

I was writing the same response when I noticed that you had beaten me to it.

Natural gas is 70-90 methane by weight. This makes it's short-term greenhouse effect very great.
