Permission will be given only after an examination of current Repository holdings has been completed by respective staff and after the supply of a comprehensive list of material to be removed for analysis.

Approval is subject to the volumes of material available and a review of the results obtained from previous destructive analyses.

When sampling core for destructive analysis, the minimum sample amount required to complete the analysis should be taken. It is expected that the sample will be consumed in analysis; however, if the core is not destroyed, contaminated or consumed, it is to be returned to the core facility of origin within six months of the sampling date. Core sampling will be limited to a ¼ core section by volume and representative ¼ core section will be retained for archiving purposes.

When sampling cuttings for destructive analysis, the minimum sample amount required to complete the analysis should be taken. It is expected that the sample will be consumed in analysis; however, if the cuttings are not destroyed, contaminated or consumed, it is to be returned to the core facility of origin within six months of the sampling date. Cuttings will be limited to 10g per interval and 50g will be retained for archiving purposes. Samples from cuttings must be representative of the total sample (selective sampling of chips from a particular lithology is not permitted).

A detailed inventory of all samples and volumes taken from each well and the purpose for which they were taken is to be supplied at the completion of sampling.

For WA State wells one copy of the report with results and methods of all analyses must be submitted within six months of the sampling date, on digital media to:

For open file Commonwealth wells one copy of the report with results and methods of all analyses must be submitted within six months of the sampling date, on digital media to:

For confidential Commonwealth wells one copy of the report with results and methods of all analyses must be submitted within six months of the sampling date, on digital media to:

Requests for extensions to submission timeframes must be applied for in writing to:
petdata@dmirs.wa.gov.au for WA State wells
ausgeosamples@ga.gov.au for open file Commonwealth wells

Analysis reports created from confidential sample access will remain in confidence until after the relevant day of the activity(s) has passed.
Analysis reports created from open file samples will become publicly available shortly after receipt of the data.

All prepared slides (palynology/thin sections etc.) from both WA State and Commonwealth wells are to be submitted to the Department of Mines, Industry Regulation and Safety within six months of the sampling date.

All samples to be sent for analysis overseas must be approved for export prior to shipment.
Requests for approval to export, must be applied for in writing to:
