Sending core overseas for analysis

You must obtain written approval prior to sending any core overseas for specialist analysis. Email your request to

The request should include details of the core to be transported, its destination and the type of analyses to be undertaken, as well as the expected date for its return to Australia and submission to the core facility. 

Core sent overseas must be shipped back to Australia and delivered to the NTGS core facilities after analysis is completed.

Fluid and gas samples

If you recover fluid or gas samples they must be analysed and kept for at least 6 months. 

If fluid or gas samples are collected please offer them to NTGS. If required they will need to be sent to Geoscience Australia in Canberra in an American Petroleum Institute (API) approved safety container.

You must submit palynological slides, slides and residues, palaentological material and petrological slides to NTGS when no longer required or prior to ceasing the permit or licence.
