247.32 acres on the newest permit

  • Good to know

    A pooling certificate (P-12) was filed

    Your tract may share its production with neighbors in a pooled unit. The unit acres the operator uses to divide production can differ from the acreage on one permit.

  • Good to know

    The wells on this lease state different acreage

    The permits state between 247.32 and 20,172 acres. Use the acres from your own division order for the well you are paid on.

  • Good to know

    509 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.
