Who buys my oilOil price check

1,471.43 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 1,309.5 and 1,471.43 acres. Use the acres from your own division order for the well you are paid on.

  • Good to know

    17 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.
