The main objective of this proposal is to determining the nature and kinetics of fluid-rock interactions between CO2-rich brines and rocks, in field settings as well as in laboratory experiments, in order to formulate and test models of the behaviour and fate of CO2 injected in geological strata. To do this we need to determine the processes which moderate the fluid-mineral reaction kinetics, particularly the nature of the processes which result in much more sluggish kinetics in field settings compared with the predictions from laboratory experiments. The ultimate objective is to creat a database and methodology that enables the results of this study to be used in risk assessments and performance modelling of geological carbon storage sites. To achieve these main objectives we will need to carry out the following: 1) Evaluate natural (CO2 natural gas reservoirs) and anthropogenic (CO2 injection EOR - Enhanced Oil Recovery) sites as analogues for geological CO2 storage. As necessary, determine the hydrology and the nature of the CO2-fluid to reservoir brine interactions in these sites and characterise the reservoir mineralogy, mineral characteristics that might control reaction rates (e.g. mineral surface areas and topologies) and fluid-mineral reactions by using a range of mineralogical, geochemical and isotopic analytical techniques. 2) Carry out laboratory experiments on reservoir materials, cap rocks and single minerals to investigate mineral-fluid reactions and reaction kinetics under controlled conditions and to test the reactions and reaction kinetics inferred from the field-scale studies. 3) Perform laboratory experiments to make detailed measurements of noble gas solubility in, and partitioning between, supercritical and liquid CO2 and brine and extend the data available for the natural analogues to include high precision noble-gas isotopic and concentration data. This data will inform modelling of the hydrology of the naturalCO2 reservoirs. 4) Utilise existing and develop improved thermodynamic modelling of both equilibrium and kinetically-rate limited mineral-fluid reactions to a) relate the results of field-based and laboratory experiments, b) enable more general application of the results from this and other studies to specific field sites and c) use the laboratory and field results to test the applicability of widely used thermodynamic models for mineral reaction rates.

本提案的主要目的是确定富CO2卤水和岩石之间的流体-岩石相互作用的性质和动力学，在现场设置以及在实验室实验中，以制定和测试模型的行为和命运的CO2注入地质地层。要做到这一点，我们需要确定的过程，缓和流体矿物反应动力学，特别是过程的性质，导致在现场设置的动力学更缓慢的实验室实验的预测相比。最终目标是建立一个数据库和方法，使这项研究的结果能够用于风险评估和地质碳储存地点的性能建模。为了实现这些主要目标，我们将需要开展以下工作：1）评估天然（CO2天然气藏）和人为（CO2注入EOR -提高石油采收率）场地作为CO2地质封存的类似物。必要时，确定这些地点的水文学和CO2-流体与储层盐水相互作用的性质，并通过使用一系列矿物学、地球化学和同位素分析技术，确定可能控制反应速率（例如矿物表面积和拓扑结构）和流体-矿物反应的储层矿物学、矿物特征。2)对储层材料、盖层和单一矿物进行实验室实验，以研究受控条件下的矿物-流体反应和反应动力学，并测试从实地规模研究中推断的反应和反应动力学。3)进行实验室实验，详细测量稀有气体在超临界和液态CO2和盐水中的溶解度以及它们之间的分配情况，并扩展天然类似物的可用数据，以包括高精度的稀有气体同位素和浓度数据。这些数据将为自然CO2水库的水文建模提供信息。4)利用现有的平衡和动力学速率受限的矿物-流体反应的热力学模型，并开发改进的热力学模型，以a）将基于现场的实验和实验室实验的结果联系起来，B）使本研究和其他研究的结果能够更普遍地应用于特定的现场，以及c）使用实验室和现场结果来测试广泛使用的矿物反应速率热力学模型的适用性。
