Caveats

  • ⚠ The upstream layer is named AbandonedWell but contains licences across all published licence statuses.
  • ⚠ Licensee is the legal licence holder and must not automatically be interpreted as the current well operator.
  • ⚠ AER blocks LIKE/IN/UPPER expressions, so licensee, status, and fluid filters are exact matches.

    • ⚠ Exact-match string filters follow AER WAF restrictions.
    • ⚠ truncated=true means call again with nextOffset; complete=false until all pages are collected.
    • ⚠ Licensee identifies the legal licence holder, not necessarily the current operator.
