491.05 acres on the newest permit
- Worth asking
An allocation well is on this lease
A well drilled across several tracts shares its production by an allocation formula, so the decimal is not always your acres over the unit acres. Ask the operator for the allocation formula and the tract factor for your land.
- Good to know
The wells on this lease state different acreage
The permits state between 491.05 and 639.49 acres. Use the acres from your own division order for the well you are paid on.
- Good to know
12 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 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.
