The original Aune Federal well goes N-S with 32 & 29H. That spacing was 1280 since it was two sections. What was your original royalty and decimal amount on the first well? The lease may have said 40 acres, but that might be the tract gross acreage, not her actual mineral acres. Do you have exact wording from a deed or a will? Trying to work backwards here.
The new wells are going East West and go across three sections for the 1919.2 spacing acres. So whatever her net mineral acres are would be included in the new well spacings which are larger. Her decimal amount will be less, but the additional wells will be nice.
