Working Interest Division Order Help

I think I have finally figured out how the Operator is billing for JIB statements and paying on revenue for my working interest. It looks like our WI is Unit wide and r the revenue department states they invoice by the well throughout the entire Unit. Then all revenue regardless of whether a working interest owner elects to participate in new wells or not goes in to one big bowl for the entire Unit and is distributed out according to Tract Participation and then further distributed by the working interest owners interest decimal in the specific Tract. In my opinion it doesn’t amount to much revenue even with numerous new long lateral wells drilled. It’s distributed so much through the Unit and then down to your specific interest that it almost seems like a bad deal but it is what it is for a reason. It’s an old Operating Agreement from 1959 for the Spraberry Unit in multiple counties with Pioneer as the Operator. So I’m guessing they possibly did working interest a bit differently way back then or I’m just not understanding it. Either is possible. But I was under the impression Working Interest gave gave the owner of the interest options to participate in wells and then receive a Net Revenue Interest of any potential revenue from those wells. I didn’t know it was distributed down throughout a very large unit and then your interest comes in to play only for the Tracts. But the Working Interest is contractual and invoiced by the well Unit Wide not by the Tract. Does that seem right to anyone? The way they have it now we basically pay right back out with our JIB statement what you make in our revenue statement no matter whether you participate in new wells or other types of AFEs wise.
