Understanding inter-aquifer connectivity or leakage of greenhouse gases and groundwater to aquifers overlying gas reservoirs is important for environmental protection and social licence to operate. Australia's Great Artesian Basin (GAB) is the largest artesian groundwater system in the world with groundwater extracted for agriculture, livestock, mines, energy, private or town water supply. Microbial coal seam gas (CSG) and production water are also extracted from the GAB. Here a range of groundwater tracers is used to investigate the potential for gas and groundwater connectivity between the CSG reservoir and aquifers.

与煤层气藏上方含水层中甲烷相关的地球化学示踪剂


了解含水层间的连通性或温室气体和地下水向气藏上方含水层的泄漏对于环境保护和社会运营许可非常重要。澳大利亚大自流盆地 (GAB) 是世界上最大的自流地下水系统，提取的地下水用于农业、畜牧业、矿山、能源、私人或城镇供水。微生物煤层气 (CSG) 和生产水也从 GAB 中提取。这里使用一系列地下水示踪剂来研究 CSG 储层和含水层之间天然气和地下水连通的潜力。
