When contacting Xterra about a revenue statement question, I was advised that they were holding revenue in suspense waiting for signed division orders that I had never received. They supplied the division orders via .pdf documents. Upon review I discovered part of the wells reflected royalty interest calculations based on a 1/8 royalty reserve and part based on a 3/16 royalty reserve. Since all the wells are covered by the same royalty deed and each group of 10 wells were in very close proximity and were covered by the same abstracts, I amended the lower royalty interests to match the higher reserve, initialed all changes, signed the division orders and submitted them via .pdf documents in May of this year. They removed me from suspense and began paying revenue, but the amendments have not been made and I have received no communication on the subject. How long should it take for a review and reply? What should be my next step?
