10,849.31 acres on the newest permit

  • Good to know

    The wells on this lease state different acreage

  • Good to know

    A substandard-acreage flag is in the permit records

    The RRC permit records include a substandard-acreage flag. Ask which acreage applies to your well and how it was used in your decimal.

  • 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.
