Are you a non-operating working interest owner or a royalty owner?
If you are a royalty owner, you might take a look at N.D. Century Code 38-08-06.4. Generally speaking, an operator cannot flare gas produced after a one-year period from the date of first production from the well. With that said, there are several exceptions to this statutory requirement.
If your operator is in violation of this statute (and you are a royalty owner), then the operator shall pay royalties to royalty owners upon the value of the flared gas. N.D.C.C. § 38-08-06.4 (4).
