Bulk Oils Database Table

The bulk oils database table contains publicly available results from Geoscience Australia's organic geochemistry (ORGCHEM) schema and supporting oracle databases for the bulk properties of petroleum liquids (e.g., condensate, crude oil, bitumen) sampled from boreholes and field sites. The analyses are performed by various laboratories in service and exploration companies, Australian government institutions, and universities using a range of instruments. Petroleum is composed primarily of hydrocarbons (carbon and hydrogen) with minor quantities of heterocyclic compounds containing either nitrogen, oxygen or sulfur. Data includes the borehole or field site location, sample depth, shows and tests, stratigraphy, analytical methods, other relevant metadata, and various data types including; API gravity, elemental composition and photographs of the samples. The stable carbon (13C/12C) and hydrogen (2H/1H) isotopic ratios of crude oil and derivative saturated and aromatic hydrocarbon fractions are presented in parts per mil (‰) and in delta notation as δ13C and δ2H, respectively. Results are also included from methods that separate crude oils into bulk components, such as the quantification of saturated hydrocarbon, aromatic hydrocarbon, resin, and asphaltene (SARA) fractions according to their polarity.These data provide information about the petroleum fluid’s composition, source, thermal maturity, secondary alteration, and fluid migration pathways. They are also useful for enhanced oil recovery assessments, petroleum systems mapping and basin modelling. Hence, these sample-based datasets are used for the discovery and evaluation of sediment-hosted resources. Some data are generated in Geoscience Australia’s laboratory and released in Geoscience Australia records. Data are also collated from destructive analysis reports (DARs), well completion reports (WCRs), and literature. The bulk oils data are delivered in the Petroleum Bulk Properties and Stable Isotopes web services on the Geoscience Australia Data Discovery Portal at https://portal.ga.gov.au which will be periodically updated.

全量石油数据库表收录了澳大利亚地质调查局（Geoscience Australia）有机地球化学（ORGCHEM）数据模型及其配套Oracle数据库中公开的石油流体体相性质分析结果，这些流体包括从钻孔和野外现场采集的凝析油、原油、沥青等。该分析由多家服务与勘探企业、澳大利亚政府机构及高校的实验室借助各类仪器设备完成。石油主要由烃类（碳和氢组成）构成，同时含有少量含氮、氧或硫的杂环化合物。数据集包含钻孔或野外现场位置、样品埋深、油气显示与测试结果、地层、分析方法及其他相关元数据，同时涵盖多种数据类型：API比重、元素组成以及样品照片。原油及其衍生的饱和烃、芳烃馏分的稳定碳（13C/12C）与氢（2H/1H）同位素比值，以千分比（‰）及δ标记法分别表示为δ13C与δ2H。此外还收录了基于极性分离原油体相组分的分析结果，例如按照极性分级对饱和烃、芳烃、树脂及沥青质（SARA）馏分进行定量检测的数据。这些数据可用于解析石油流体的组成、来源、热成熟度、次生蚀变以及运移路径，同时可用于强化采油评估、石油系统制图及盆地模拟。因此，这批基于样品的数据集可用于沉积型矿产资源的勘探与评价。部分数据由澳大利亚地质调查局实验室生成，并收录于其官方公开记录中。数据集还整合了破坏性分析报告（DARs）、完井报告（WCRs）及公开文献中的相关数据。全量石油数据集通过澳大利亚地质调查局数据发现门户（https://portal.ga.gov.au）的"Petroleum Bulk Properties and Stable Isotopes"网络服务进行发布，该数据集将定期更新。
