摘要

页岩具有低至超低的孔隙度和渗透率,这使其成为CO2强化采油(CO2 EOR)或地质CO2储存(GCS)过程中CO2利用的有吸引力的候选者。页岩是烃源岩,因此,存在一个连续的诱导成岩过程,当它们在更高的原位温度下达到成熟度时,会改变它们的性质。然而,在该成岩过程(热成熟)中利用CO2以实现长期CO2储存的可能性方面存在重大知识差距。本实验研究调查了由于在原位条件下诱导热成熟而在页岩中利用CO2的潜力,以及在页岩中注入成熟前CO2对GCS和CO2提高采收率的影响。在这里,我们使用了暴露在CO2中一段特定时期的地下富烃Bakken和Green River页岩。然后将未暴露和暴露于CO2的页岩诱导至热成熟期。随后,我们评估了总有机碳(TOC)、释放的碳氢化合物(S2)以及成熟页岩和暴露于CO2的成熟页岩的矿物学和力学性质。我们进一步评估了热成熟Bakken和Green River页岩中CO2利用和储存对长期储存或CO2 EOR的影响。结果表明,如果在达到成熟度之前将CO2注入页岩,那么当巴肯页岩(+30%释放的碳氢化合物;−31%杨氏模量;−34%硬度)和格林河页岩(+8%释放的烃;−40%杨氏模量;–30%硬度)达到成熟度时,预计会有更高的碳氢化合物产量和更显著的机械弱点,这是相对于在达到热成熟度之前没有注入CO2的Bakken和Green River页岩而言的。此外,暴露于CO2的成熟Bakken和Green River页岩可以通过白云石的溶解和方解石的沉淀改变页岩中的矿物,从而促进矿物捕获并实现较低的TOC(Bakken页岩=−24%;Green River页岩=−26%),这与成熟前未注入CO2的Bakken或Green River页岩有关。对结果的分析表明,在未成熟页岩中应用这种拟议的CO2注入和利用可以在Bakken和Green River页岩中获得更优秀的CO2储存储层,而无需等待更长的时间使页岩变得可行和成熟,这就是目前全球页岩储层的GCS和CO2 EOR操作的情况。此外,我们提出的预成熟CO2注入可以通过CO2 EOR使成熟页岩恢复活力,增加碳氢化合物产量,提高密封效率,并降低长期CO2储存的泄漏风险。这项研究的结果提供了新的见解,可以促进未成熟Bakken和Green River页岩未来GCS和/或CO2 EOR的CO2利用,同时通过消耗大气中的CO2来提供一个即时可行的储存选择,以在2050年前实现全球净零排放。©2023化学工业协会和John Wiley&Sons,有限公司。

CO2-Induced alterations due to thermal maturation in shale: Implications for CO2 utilization and storage

Shales have low to ultra-low porosity and permeability, which makes them an attractive candidate for CO2 utilization during CO2-enhanced oil recovery (CO2-EOR) or for geologic CO2 storage (GCS). Shale are source rocks, and thus, there is a continuous induced diagenetic process that can alter their properties as they reaches maturity at greater in situ temperature. However, there are significant knowledge gaps in the possibility of CO2 utilization during this diagenetic process (thermal maturation) to achieve long-term CO2 storage. This experimental study investigates the potential for CO2 utilization in shale due to induced thermal maturation at in situ conditions, and the implications of pre-maturation CO2 injection in shale for GCS and CO2-EOR. Here, we used subsurface hydrocarbon-rich Bakken and Green River shales exposed to CO2 for a specific period. This is followed by inducing the unexposed and CO2-exposed shales to thermal maturity. Subsequently, we evaluated the total organic carbon (TOC), liberated hydrocarbons (S2), and the mineralogical and mechanical properties of the mature and CO2-exposed mature shales. We further assessed the implications of CO2 utilization and storage in thermally matured Bakken and Green River shales for long-term storage or CO2-EOR. The results indicate that if CO2 is injected into shales before attaining maturity, higher hydrocarbon production and more significant mechanical weakness can be expected when they attain maturity in Bakken shales (+30% liberated hydrocarbons; −31% Young's modulus; −34% hardness) and Green Rivers shales (+8% liberated hydrocarbons; −40% Young's modulus; −30% hardness), and this is relative to Bakken and Green River shales without CO2 injection before attaining thermal maturity. Further, CO2-exposed mature Bakken and Green River shales can alter the minerals in shales with the dissolution of dolomite and precipitation of calcite, which promotes mineral trapping and achieve a lower TOC (Bakken shale = −24%; Green River shale = −26%), and this is relative to Bakken and Green River shales without CO2 injection before attaining maturity. Analyses of the results suggest that the application of this proposed CO2 injection and utilization in immature shales could access more excellent CO2-storage reservoirs in Bakken and Green River shales without waiting for a more extended period for the shales to become viable and mature, which is the case with the present GCS and CO2-EOR operations in shale reservoirs globally. Also, our proposed pre-maturation CO2 injection could rejuvenate mature shales for increased hydrocarbon production through CO2-EOR, yield a greater sealing efficiency, and mitigate leakage risks for long-term CO2 storage. The results from this study provide novel insights that can advance CO2 utilization for future GCS and/or CO2-EOR in immature Bakken and Green River shales while at the same time providing an immediate and viable option for storage by depleting atmospheric CO2 to meet the global net-zero by 2050. © 2023 Society of Chemical Industry and John Wiley & Sons, Ltd.

期刊介绍: Greenhouse Gases: Science and Technology is a new online-only scientific journal dedicated to the management of greenhouse gases. The journal will focus on methods for carbon capture and storage (CCS), as well as utilization of carbon dioxide (CO2) as a feedstock for fuels and chemicals. GHG will also provide insight into strategies to mitigate emissions of other greenhouse gases. Significant advances will be explored in critical reviews, commentary articles and short communications of broad interest. In addition, the journal will offer analyses of relevant economic and political issues, industry developments and case studies. Greenhouse Gases: Science and Technology is an exciting new online-only journal published as a co-operative venture of the SCI (Society of Chemical Industry) and John Wiley & Sons, Ltd
