One of the most innovative and effective technologies developed in recent decades for reducing carbon dioxide emissions to the atmosphere is carbon capture and storage (CCS). It consists of capture, transport and injection of CO₂ produced by energy production plants or other industries. The injection takes place in deep geological formations with the suitable geometrical and petrophysical characteristics to trap CO₂ permanently in the subsurface, which is called geological storage. In the development process of a potential geological storage site, correct capacity estimation of the injectable volumes of CO₂ is one of the most important aspects. There are various approaches to estimate CO₂ storage capacities for potential traps, including geometrical equations, dynamic modelling, numerical modelling and 3D modelling. In this work, the generation of 3D petrophysical models and equations for calculation of the storage volumes are used to estimate the effective storage capacity of four potential saline aquifers in the Adriatic Sea offshore. The results show how different saline aquifers, with different lithologies at favourable depths, can host a reasonable amount of CO₂, which will require further and more detailed feasibility studies for each of these structures. A detailed analysis is carried out for each saline aquifer identified, varying the parameters of each structure identified and adapting them for a realistic estimate of potential geological storage capacity.

近几十年来，用于减少向大气中排放二氧化碳的最具创新性和最有效的技术之一是碳捕获和储存 (CCS)。它由能源生产厂或其他行业产生的 CO ₂的捕获、运输和注入组成。注入发生在具有合适几何和岩石物理特性的深层地质层中，以将 CO ₂永久地捕获在地下，这称为地质封存。在潜在地质封存场址的开发过程中，正确估算可注入 CO _{2 的}容量是最重要的方面之一。有多种估算 CO _{2 的方法}潜在陷阱的存储能力，包括几何方程、动态建模、数值建模和 3D 建模。在这项工作中，用于计算存储量的 3D 岩石物理模型和方程的生成用于估计亚得里亚海近海四个潜在盐水含水层的有效存储容量。结果表明，在有利深度具有不同岩性的不同咸水含水层如何能够容纳合理数量的 CO ₂，这将需要对这些结构中的每一个进行进一步和更详细的可行性研究。对每个识别出的咸水层进行详细分析，改变每个识别出的结构的参数，并使它们适应潜在地质存储容量的现实估计。
