Permit records can indicate requested drilling, recompletion, deepening, or related work, but do not guarantee drilling or production.

Directional surveys, plats, and L-1 records can be important for understanding horizontal wells beyond the surface point.

Completion filings can show that a well moved from permitted or drilled status into a completed well record.

Production signals help identify wells with linked monthly production or derived producing status.

P-4 activity can indicate operator, lease, gatherer, purchaser, or responsibility changes tied to the record.

Plugging notices and plugging records help distinguish planned plugging from wells already reported as plugged.
