Permission will be given only after an examination of current holdings within the Core Library/ Core Repository by respective staff and 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 achieve the analysis should be taken, and it is expected that the sample will be consumed in the analysis. Core sampling will be limited to a 1/4 core section by volume and a representative 1/4 core section will be retained for archiving purposes. If the core is not destroyed, contaminated or consumed in analysis it is to be returned to the core facility of origin within 6 months of the sampling date.

When sampling cuttings for destructive analysis, the minimum sample amount required to achieve the analysis should be taken, and it is expected that the sample will be consumed in the analysis. Cuttings sampling 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). If the cuttings are not destroyed, contaminated or consumed in analysis it is to be returned to the core facility of origin within 6 months of the sampling date.

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

For WA State wells one copy of the report with results and methods of all analyses must be submitted to the WA " + Department of Mines, Industry Regulation and Safety + " on digital media to the Manager or alternatively via email (10Mb limit) to petdata@dmirs.wa.gov.au within 6 months of the sampling date.

For Commonwealth wells one copy of the report with results and methods of all analyses must be submitted to the NOPDCR on digital media to the Manager or alternatively via email (15Mb limit) to ausgeosamples@ga.gov.au within 6 months of the sampling date.

The report(s) will be made open file data, for public inspection, 6 months after the sampling date. Extensions to this timeframe must be applied for in writing to:

All prepared slides (palynology / thin sections etc.) from both WA State and Commonwealth wells are to be submitted to the WA " + Department of Mines, Industry Regulation and Safety + " within 6 months of the sampling date.
