My royalty check production dose not match the RRC production records?

Could some one please explain why

Make sure the date of production matches. RRC site should be one month in front of your current check.

Also make sure that you are looking at the disposition to match to your check. Production is not what you check will be based on, its only based on what was sold the month that your check is for. Should have beginning storage and ending storage. I am talking about oil. My gas numbers are all over the board on MCF BTU charges and such but all in total my well is 98% oil so never pay much attention to gas numbers
