National Geoscience Mapping Accord (NGMA) Cooper Eromanga Basins Project - Cooper Formation Depths

## **Abstract** \n\nThis dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.\n\n\n\nThis dataset includes sun shaded representations of Cooper and Eromanga Basins formation thickness grids generated from seismic interpretation grids for various depths in the Cooper and Eromanga Basin areas in the north-east of South Australia, south-west northern territory, south-east Queensland and north-east New South Wales.\n\n\n\nThese grids are part of a database of seismically mapped subsurface isopach, time and depth grids, contours, faults and polygons interpreted from Seismic mapping for the National Geoscience Mapping Accord (NGMA) Cooper and Eromanga Basins, Australia, Seismic Mapping Project.\n\n\n\nFull metadata for each grid can be viewed at: http://www.pir.sa.gov.au/minerals/sarig2/metadata/seismic_horizons_-_sun_shaded_timedepth_isopach_images/cooper\n\n## **Purpose** \n\nUsage\n\nPurpose:\n\n\n\nTo develop and promote new petroleum exploration and development opportunities in the Cooper and Eromanga Basins, Australia\n\n\n\nUse:\n\n\n\nGeological and prospectivity evaluation.\n\n## **Dataset History** \n\nThese data were derived from well tops, seismic sections and some open file industry interpretations.\n\n\n\nInterpretations over the South Australian sector derived from basic seismic data, with some reference to open file industry and other data.\n\n\n\nInterpreted, compiled and edited by Brent Jensen-Schmidt, (consulting geophysicist), Don Vinall and many PIRSA staff.\n\n\n\nOverall supervision by Dave Cockshell, Chief Petroleum Geophysicist, Petroleum Geophysics Branch, OFFICE OF MINERALS AND ENERGY RESOURCES, PRIMARY INDUSTRIES AND RESOURCES, SOUTH AUSTRALIA.\n\n\n\nInterpretations over the Queensland sector compiled and edited by Kinta Hoffman with Owen Dickson and Julie Dingwall.\n\n\n\nOverall supervision by John Draper, Project Leader, Hydrocarbon Geology Group, Geological Survey Office, QUEENSLAND DEPARTMENT OF MINES AND ENERGY.\n\n\n\nInterpretations over the Northern Territory sector derived from basic seismic data, with some reference to open file industry and other data.\n\n\n\nInterpreted, compiled and edited by Brent Jensen-Schmidt, supported by PIRSA staff.\n\n\n\nOverall supervision by Greg Ambrose, Senior Petroleum Geologist, NORTHERN TERRITORY DEPARTMENT OF MINES.\n\n\n\nInterpretations over the New South Wales sector derived from borehole data provided by the NSW DEPARTMENT OF MINERAL RESOURCES.\n\n\n\nInterpreted, compiled and edited by Brent Jensen-Schmidt, supported by PIRSA staff.\n\n\n\nMerging of data across state boundaries by Brent Jensen-Schmidt, and Don Vinall of PIRSA.\n\n\n\nCoordinated by Tony Hill, Acting Manager, Petroleum Geology Branch, OFFICE OF MINERALS AND ENERGY RESOURCES, PIRSA.\n\n\n\nPositional Accuracy:\n\n\n\nPixel size\n\n\n\nAttribute Accuracy:\n\n\n\nThe (P) to (Z) isopach accuracy is dependent on the Basement and Permian depth grids accuracies. Seismic interpretation of top Permian in the Cooper Basin area is reasonably straight forward. The interpreted depth value at wells that penetrate the Permian top used in the depth conversion is within 2 metres of the Permian well pick. Seismic interpretation of top Basement in the Eromanga Basin area is difficult. The interpreted depth value at wells that penetrate the Basement used in South Australia and Northern Territory is within 2 metres of the Basement well pick.\n\n\n\nLogical Consistency:\n\n\n\nHighly consistent\n\n\n\nCompleteness:\n\n\n\nComplete\n\n## **Dataset Citation** \n\n"SA Department for Manufacturing, Innovation, Trade, Resources and Energy" (2003) National Geoscience Mapping Accord (NGMA) Cooper Eromanga Basins Project - Cooper Formation Depths.

**摘要**
本数据集及其元数据声明由第三方提供给生物区域评估计划（Bioregional Assessment Programme），此处按原始提交内容呈现。

本数据集包含库珀盆地（Cooper Basin）与埃罗曼加盆地（Eromanga Basin）的日照晕渲地层厚度网格，此类网格基于南澳大利亚州东北部、北领地西南部、昆士兰州东南部以及新南威尔士州东北部的库珀与埃罗曼加盆地区域内不同深度的地震解释网格生成。

此类网格隶属于澳大利亚国家地球科学制图协定（National Geoscience Mapping Accord, NGMA）库珀与埃罗曼加盆地地震测绘项目所生成的地震制图地下等厚线（isopach）、时间与深度网格、等值线、断层及多边形数据库。

**数据集用途**
核心目的：
为澳大利亚库珀与埃罗曼加盆地开发并推广全新的石油勘探与开发机遇。
应用场景：
开展地质与勘探远景评价。

**数据集历史**
本数据集源自测井顶界、地震剖面以及部分公开的行业解释成果。

南澳大利亚州区域的解释成果基于基础地震数据，并参考了公开行业数据及其他相关资料。该部分成果由地球物理咨询专家Brent Jensen-Schmidt、Don Vinall以及多名南澳大利亚州初级产业与资源部（Primary Industries and Resources South Australia, 简称PIRSA）工作人员进行解释、编译与编辑，整体监督工作由南澳大利亚州矿产与能源资源办公室、初级产业与资源部石油地球物理部门首席石油地球物理学家Dave Cockshell负责。

昆士兰州区域的解释成果由Kinta Hoffman、Owen Dickson与Julie Dingwall编译编辑，整体监督工作由昆士兰州矿产与能源部地质调查局烃类地质组项目负责人John Draper负责。

北领地区域的解释成果基于基础地震数据，并参考了公开行业数据及其他相关资料，由Brent Jensen-Schmidt在PIRSA工作人员协助下完成解释、编译与编辑，整体监督工作由北领地矿产部高级石油地质学家Greg Ambrose负责。

新南威尔士州区域的解释成果源自新南威尔士州矿产部提供的钻孔数据，由Brent Jensen-Schmidt在PIRSA工作人员协助下完成解释、编译与编辑。

跨州界的数据合并工作由Brent Jensen-Schmidt与PIRSA的Don Vinall完成，协调工作由PIRSA矿产与能源资源办公室石油地质部门代理经理Tony Hill负责。

**位置精度**
像素尺寸
**属性精度**
（P）至（Z）等厚线精度取决于基底与二叠系深度网格的精度。库珀盆地区域的二叠系顶界地震解释工作相对直观，深度转换过程中所使用的钻穿二叠系顶界的井的解释深度值与二叠系井界选取值的误差在2米以内。埃罗曼加盆地区域的基底顶界地震解释难度较高，南澳大利亚州与北领地所使用的钻穿基底的井的解释深度值与基底井界选取值的误差在2米以内。

**逻辑一致性**：高度一致
**完整性**：完整
