Who buys my oilOil price check

642.70 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 642.7 and 805.84 acres. Use the acres from your own division order for the well you are paid on.

  • 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.
