Report a petroleum discovery
- the presence of petroleum in a reservoir (an accumulation) is indicated during drilling
- and the petroleum is shown to be producible.
You must notify the Northern Territory Government when the petroleum discovered is:
- part of a new discrete accumulation
- outside the known limits of an existing pool
- a previously unknown phase of producible petroleum (such as an oil rim or new gas reservoir) in a known pool.

This report must include the:
- information in the initial report
