Characterization of the Triassic Newark Basin of New York and New Jersey for Geologic Storage of Carbon Dioxide

The project Characterization of the Triassic Newark Basin of New York and New Jersey for Geologic Storage of Carbon Dioxide is one of 9 site characterization projects that were implemented as part of ARRA (American Recovery and Reinvestment Act). Data from this project was used to improve resolution of data in NATCARB in the area of study. Data related to this study has already been incorporated in NATCARB Atlas. Sandia Technologies, LLC, and co-investigator Conrad Geoscience Corporation, examined the potential for large-scale, permanent CO2 storage in sedimentary strata within the Newark Rift Basin. The Newark Rift Basin underlies an industrialized, developed region comprising parts of New York, New Jersey, and Pennsylvania. The project characterized and investigated the suitability of Triassic age sedimentary formations for potential geologic CO2 storage. The project team drilled and cored two test wells to define the sedimentary geologic formations underlying the basin and to document or reach basement rock. With this geologic characterization phase, an integration of seismic, geologic, borehole, and formation core results provided a higher resolution assessment of CO2 storage potential. The Stockton Formation is known to be a potentially favorable geologic storage formation in the basin. In 2011, the 1-NYSTA Tandem Lot stratigraphic test well was drilled to a depth of 6,855 feet in the northern portion of the Newark Basin in southern New York State. Approximately 9 miles south-southeast on the Lamont Doherty Campus, TW-4 was drilled and cored in 2013 to a depth of 1,802 feet and contacted apparent igneous basement at a depth of 1,712 feet. Both wells penetrated the Palisades Sill ranging from 800 feet thick in the eastern well to approximately 1,800 feet in thickness at the 1-NYSTA Tandem Lot deep drill site. A diabase sill can provide an excellent seal and dense confining layer for potential CO2 storage reservoirs and flow layers that are situated beneath it within the Stockton Sandstone. The Stockton Sandstone was encountered beneath the sill in the TW-4 well on the Lamont campus, and data integration suggests that it was likely observed near total depth in the deep 1-NYSTA Tandem Lot well. The test wells confirm and define reservoirs are present beneath the sill and offer CO2 storage potential. The integration of geologic and reservoir characterization of well logs, formation cores, and formation fluids indicated Triassic age lacustrine playa lake and mudbank shales of the Upper Passaic Group can provide an effective seal for the porous and permeable underlying sandstone reservoir layers. This project acquired seismic data, drilled borehole well logs, acquired core samples, and integrated these findings to provide a better understanding of the subsurface geologic formations in the Newark Rift Basin. These findings have contributed to a higher degree of accuracy in predicting potential geologic storage opportunities, while refining geologic storage capacity estimates for the indicated reservoirs and flow units.

《纽约与新泽西三叠纪纽瓦克盆地二氧化碳地质封存特征研究》项目是ARRA（美国复苏与再投资法案）框架下实施的9个场地特征研究项目之一。该项目数据用于提升研究区域内NATCARB数据集的分辨率，相关研究数据已纳入NATCARB图集。桑迪亚技术有限责任公司（Sandia Technologies, LLC）及其合作研究者康拉德地球科学公司（Conrad Geoscience Corporation）探讨了纽瓦克裂谷盆地内沉积地层大规模永久封存二氧化碳的潜力。纽瓦克裂谷盆地位于纽约、新泽西及宾夕法尼亚部分地区构成的工业化发达区域之下。项目对三叠纪沉积地层用于二氧化碳地质封存的适宜性开展了特征分析与评估，团队钻探并取芯两口测试井以明确盆地下伏沉积地质构造、记录或触及基岩。通过整合地震、地质、钻孔及地层岩芯数据，该地质特征分析阶段实现了更高分辨率的二氧化碳封存潜力评估。斯托克顿组（Stockton Formation）是盆地内潜在的优良地质封存层系。2011年，在纽约州南部纽瓦克盆地北部钻探1-NYSTA Tandem Lot地层测试井，深度达6855英尺；2013年，在拉蒙特·多尔蒂校区东南偏南约9英里处钻探并取芯TW-4井，深度1802英尺，于1712英尺处触及明显火成岩基岩。两口井均穿透帕利塞德岩床（Palisades Sill），其厚度在东部井为800英尺，在1-NYSTA Tandem Lot深钻位点约为1800英尺。辉绿岩岩床可为其下方斯托克顿砂岩内的潜在二氧化碳封存储层及流动层提供优良封闭层与致密隔层。拉蒙特校区TW-4井在岩床下发现斯托克顿砂岩，数据整合表明1-NYSTA Tandem Lot深井总深度附近或也存在该砂岩。测试井证实并明确岩床下存在具备二氧化碳封存潜力的储层。整合测井、地层岩芯及地层流体的地质与储层特征分析显示，上帕塞伊克群（Upper Passaic Group）的三叠纪湖相干盐湖及泥滩页岩可为下方多孔渗透砂岩储层提供有效封闭。项目通过采集地震数据、钻探测井、获取岩芯样本并整合结果，深化了对纽瓦克裂谷盆地下伏地质构造的理解，提升了潜在地质封存机会预测的准确性，同时优化了目标储层与流动单元的地质封存容量估算。
