I was just wondering what is customary. A unit a family member is in seemed to have that kind of structure but a year into the arrangement the operator petitioned and was apparently granted the ability to change the structure to where the wells had to be in their sub-unit for members of that sub-unit to participate in the royalty allocation. And, they no longer participated in the royalties of wells drilled in other parts of the larger unitization. Seems a little sketch.
