C-101 APD document
Permit signal derived from a New Mexico OCD C-101 / APD filing linked to a public well card.
What it means
A C-101 / APD is a New Mexico drilling-permit signal. It usually appears when an operator is asking for approval to drill, re-enter, deepen, plug back, or add a zone on a well.
Why it matters
This is one of the earliest public signals that a new well or major wellbore change may be moving forward.
