Apparently, it's free. I see a lot of them with pipes venting the gas and it's just being set on fire. It's mostly methane and needs very little processing. I would imagine that the oil companies have invokes legislation that requires them to burn it.

Landfill gas is essentially Methane and CO2 in about a 50/50 mixture. It is flamable so in the U.S. landfills must collect the gas to prevent it from leaking out and causing fires and explosions in nearby buildings (this has happened in the past). In most cases, the collected gas is just burned in a flare. In some cases, people have made deals with the landfill to purchase the gas (or maybe to just collect it at their cost). It must then be treated to remove the CO2, water and trace impurities before it is sold to natural gas distributors. The collected CO2 is usually just vented, but it could be either sequestered or treated and sold.

Most gases like that have all kinds of gas. Methane and CO2 is not a good combination to burn so it must be treated to separate the good gas from the bad.
