480.28 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 480.28 and 480.31 acres. Use the acres from your own division order for the well you are paid on.
