264 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 264 and 344.25 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.
