K & H Well Service performed oil and gas well services for Tcina, Inc. but wasn't paid. K & H filed lien statements to secure payment, but the liens referenced a production unit name rather than just the exact legal description. The Oklahoma Supreme Court ruled that K & H's liens were valid and enforceable even though the lien statement wasn't perfectly precise, because it substantially complied with legal requirements and gave the property owner enough information to know which wells were involved.
Your lien doesn't have to be perfect to be enforceable—it just needs to substantially comply with state requirements and give the owner reasonable notice of which property is affected.
Include detailed legal descriptions in your lien statements, but minor variations or references to production unit names won't kill your lien if the owner can figure out which wells you worked on.
