320 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.

  • Worth asking

    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.
