Browse Basin Cretaceous and Cenozoic surface grids

Geoscience Australia completed a regional assessment of the geological carbon dioxide (CO2) storage potential and petroleum prospectivity of the Browse Basin, offshore northwest Australia. This dual-purpose basin analysis study provided a new understanding of the basin’s Cretaceous succession based on new information regarding basin evolution, sequence stratigraphy, structural architecture and petroleum systems. The basin’s tectonostratigraphic framework was updated, and the integration of revised and recalibrated biostratigraphic data with well log and seismic interpretations has enabled an improved understanding of variations in depositional facies and the spatial distribution of reservoir, seal, and source rock sections. The outputs include models and maps of environments of deposition, play fairways, common risk element maps for regional-scale assessment of CO2 storage potential and petroleum systems model

澳大利亚地球科学局（Geoscience Australia）完成了澳大利亚西北海域Browse盆地（Browse Basin）的地质二氧化碳（CO₂）封存潜力与油气勘探远景区域评估工作。这项兼具双重目标的盆地分析研究，依托盆地演化、层序地层学（sequence stratigraphy）、构造格架（structural architecture）与油气系统（petroleum systems）的全新资料，为该盆地的白垩系地层序列带来了全新认知。研究更新了该盆地的构造地层格架（tectonostratigraphic framework），并通过将修订并重新校准的生物地层数据（biostratigraphic data）与测井（well log）、地震解释（seismic interpretation）成果进行整合，进一步深化了对沉积相（depositional facies）变化规律，以及储集层（reservoir）、盖层（seal）和烃源岩（source rock）段空间展布特征的认知。本次研究的产出成果包括沉积环境模型与图件、勘探有利区带（play fairways），以及用于区域尺度二氧化碳封存潜力与油气系统评估的共同风险要素图件及油气系统模型。
