Hydrocarbon Migration and Seepage in the Timor Sea and Browse Basin North West Shelf Australia: An Integrated SAR, Geological and Geochemical Study

AGSO and in collaboration with Nigel Press and Associates, AUSLIG and Radarsat International (RSI) have undertaken an interpretative study of hydrocarbon migration and seepage in the offshore Bonaparte and Browse Basins, North-Western Australia. The study used Radarsat images, detailed water column Geochemical Sniffer and Airborne Laser Fluorosensor data, acquired over a number of many years. The intrepertations derived from these seepage technologies were compared and contrasted, and then intergrated with a wide variety of petroleum geological information, including regional seismic data, isopach maps, key reservoirs, source and sealing units and fault maps. All the data and many more have been placed into a 'regional' ArcView GIS associated with the final reports, Acrobat and Powerpoint files.

澳大利亚地质科学局（AGSO）与奈杰尔·普莱斯联合事务所（Nigel Press and Associates）、澳大利亚土地信息局（AUSLIG）及雷达卫星国际公司（Radarsat International，简称RSI）合作开展了澳大利亚西北部近海波拿巴盆地与布劳斯盆地的油气运移与渗漏解释研究。本研究采用了多年采集的雷达卫星影像、高精度水柱地球化学嗅探仪（Geochemical Sniffer）与机载激光荧光传感器（Airborne Laser Fluorosensor）数据。基于上述渗漏探测技术得到的解释结果经对比分析后，与多类石油地质资料完成融合整合，这些资料包括区域地震数据、等厚图、重点储层、烃源岩与盖层单元以及断裂分布图。所有数据及更多相关资料均已整合至配套最终报告、Acrobat文档与Powerpoint文件的“区域级”ArcView地理信息系统（ArcView GIS）中。
