Standards according to demands

APT is registered with the Achilles database for suppliers to the oil and gas industry (JQS ID: 24956). Through this service, our clients are able to obtain statements about our financial situation, HSE procedures and QMS.

APT complies with the guidelines for use of the Norwegian standards NSO-1, JR-1 and SR-1. Through this our samples are checked to ensure high quality and consistency; at least every 10th sample, plus 1 sample immediately prior to and immediately after each batch of analyses / project.

Regular testing is also undertaken through the “Norwegian Geochemical Standard Sample Project" which utilises a set of reference samples to ensure continued high quality. If any results fall outside the permissible range, our instruments are recalibrated and the batch reanalysed.

We are also proud to meet the preferred standards of each of our clients and will work with you to ensure you are satisfied with the outcome. If results from a standard at the end of a batch do not fall within your "permissible range", then the results for the whole batch will be discarded and the samples will be re-run.

In addition to following well established and documented procedures, the geochemical analyses follow guidelines as described in the internationally approved and applied standard “The Norwegian Industry Guide to Geochemical Analyses” (NIGOGA), 4th Edition (2000), and references therein. NIGOGA can be downloaded free of charge from the Norwegian Petroleum Directorate’s web site for references.

For most geochemical analyses the set of Norwegian Geochemical Standard (NGS) are used in order to verify accuracy and reproducibility of the analysis. These standards, two source rocks and one oil sample, were established by the Norwegian oil industry in the late 1990’s and approved as reference samples among oil companies and service companies, not only in Norway, but also throughout Europe and in other parts of the world. Permissible range and most likely values for these standards have been established through an extensive inter-laboratory comparison managed by the NPD. The standards are:

NGS Svalbard Rock -1 (SR-1) was collected from the southern side of Teistenberget Hill, Eastern Spitsbergen, Svalbard. About 400 kg was taken from a horizon with relatively low TOC content in the Anisian Middle Triassic Botneheia Fm. and homogenised. The sample has a mean vitrinite reflectance of 0.41 % and a mean TOC content of 2.17 %.

NGS Jet Rock-1 (JR-1) About 200 kg of the organic rich, black shale was collected from the Port Mullgrave area, Yorkshire, NE England and homogenised. The Jet Rock is classified as a member of the Toracian Whitby Mudstone Formation. The sample has a mean vitrinite reflectance of 0.47 % and a mean TOC content of 12.4 %.

NGS North Sea Oil-1 (NSO-1) is an oil (1000 litres) collected from the Oseberg Field located in block 30/9 in the Norwegian North Sea. The oil was homogenised and tapped into 12.5 litre aluminium flasks and stored at -20°C. The oil has a mean API gravity of 32.9°, a mean C15+ fraction of 77 % and a total asphaltene content of 1.9 % of the total crude.
