We describe a geological assessment for the development of a Carbon Capture and Storage (CCS) project in the atmospherically polluted area of Tula de Allende, State of Hidalgo in Central México. This study targets a deep saline reservoir system (Soyatal and El Abra formations of Cretaceous age) by performing the first detailed analysis of the geological structure and petrophysical properties of the subsurface rocks in the study area. A comprehensive study of the stratigraphy and mineralogy was conducted with rocks from México's geologic repository (Litoteca Nacional). which included petrography, permeability, and CT scanning. The results were correlated with wireline logs and drilling reports of a dry well (Jasso-1) previously drilled for petroleum prospecting in the area. The integrated data identified a potential set of carbonaceous reservoir and caprock formations, with a preliminary storage capacity of 1.1 GTCO₂.

The industrial corridor in Tula de Allende includes a 300 KBPD refinery, an 1800 MW high-sulfur fuel oil- power plant, and cement factories, which contribute to air pollution that exceeds international limits of air quality of carbon dioxide (CO₂), nitrogen oxides (NO_x), sulphur oxides (SO_x), and particulates. A CCS project would not only improve the environmental quality for local inhabitants, reducing the atmospheric pollution in the immediate area but additionally have the same effects in Mexico City. The latter is noted to have a population of over 20 million where the winds are key in transporting these pollutants from the source area of Tula de Allende.

我们描述了在墨西哥中部伊达尔戈州图拉德阿连德大气污染区开发碳捕集和封存 (CCS) 项目的地质评估。本研究通过对研究区地下岩石的地质结构和岩石物理特性进行首次详细分析，以深部咸水储层系统（白垩纪的 Soyatal 和 El Abra 地层）为目标。对来自墨西哥地质资源库 (Litoteca Nacional) 的岩石进行了地层学和矿物学的综合研究。其中包括岩相学、渗透性和 CT 扫描。结果与之前为该地区石油勘探而钻探的干井 (Jasso-1) 的电缆测井和钻井报告相关联。₂ .

图拉德阿连德的工业走廊包括一座 300 KBPD 炼油厂、一座 1800 MW 高硫燃料油发电厂和水泥厂，这些工厂造成的空气污染超过了二氧化碳 (CO ₂ )、氮气的国际空气质量限制氧化物 (NO _x )、硫氧化物 (SO _x ) 和颗粒物。CCS 项目不仅可以改善当地居民的环境质量，减少附近地区的大气污染，而且对墨西哥城也有同样的效果。后者的人口超过 2000 万，风是从图拉德阿连德源区输送这些污染物的关键。
