Excessive amounts past what is needed for local heat and electricity. North Dakota did recently pass legislation requiring more efficient/environmentally friendly storage/processing/usage of natural gas that would've previously been flared, regardless of how economically viable it is.

EDIT: I'm mistaken. North Dakota gave the industry an extra 10 months to meet these requirements.

> Governor Jack Dalrymple and the two other members of the North Dakota Industrial Commission (NDIC) voted unanimously to change the date when companies must capture 85 percent of natural gas produced from their wells to Nov. 1, 2016.

Classy North Dakota.

Because it's a massive safety risk, and believe it or not, the cost is not with doing that. There is a lot of the gas. You must control it.

Methane is heavier than air and it will pool down and make a potential FOOOOM!!! event. Unscheduled release of energy bad. Asphyxiation by methane bad. There's no odorant and you can't smell it.

It can be controlled though, you just need to be willing to pay for the infrastructure to do so.

Agreed. I'd love to see it myself.

Methane is lighter than air.

Nat. Gas may or may not be just methane. You are absolutely correct for what's called "dry gas".

This is a drill rig and does not have any oil/gas production facilities. The pressure in a well can be very unpredictable and is very dangerous to connect directly to generators/heaters. I's much safer to flare it off for the short period when plugging the well.
