  • 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.

  • 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.
