beneficiary statement for EOG RESOURCES

I have absolutely no knowledge of these things but do know I’ve been given the run around by EOG RESOURCES. We signed a lease in 2011 to drill for 3 yrs with option to extend for 2. They are still drilling. Have.only received one check from them and when I ask about this they now say I need beneficiary statement and other paperwork. They didn’t require this to get me to sign nor to send the one check they sent 4 years ago.
