Who buys my oil Oil price check

18,829.09 acres on the newest permit

Good to know
A pooling certificate (P-12) was filed
Your tract may share its production with neighbors in a pooled unit. The unit acres the operator uses to divide production can differ from the acreage on one permit.
Good to know
The wells on this lease state different acreage
The permits state between 20 and 18,830 acres. Use the acres from your own division order for the well you are paid on.
Good to know
943 wells are listed on this lease
Each well can have its own unit. The decimal for one well does not have to equal the decimal for another.
Worth asking
A substandard-acreage flag is in the permit records
The RRC permit records include a substandard-acreage flag. Ask which acreage applies to your well and how it was used in your decimal.
Worth asking
A Rule 37 case is listed
The RRC permit records list a Rule 37 case. This does not establish your royalty share. Ask for the permit and unit plat for your well.
