Price of Gas at Well

One of my wells produced 355 mcf of gas in March of this year. Problem is I am unable to convert that into dollars! Can someone give me a little guidance on doing that?

With the limited amount of information given, you can consider that somewhere in the $2.50 to $3.00/mcf is about what gas at the wellhead sells for, absent any applicable post production deductions. If you’re in an area where gas is constrained or stranded to any degree, it could be considerably less.

What is generally the difference between the wellhead price and the Henry Hub price?

It will vary a great deal, depending on where you are located and the quality of the gas. If you can provide some additional information, maybe someone can give you a more detailed answer.
