Core Flood Experiments on carbonate rocks

Grant: ACT ELEGANCY, Project No 271498. Medical CT scans for drainage multiphase flow through carbonate rock cores. The steady state drainage multiphase flow at elevated pressure using nitrogen and DI water, are carried out for three heterogeneous carbonate rocks to characterize the impact of heterogeneity on flow. Core Floods are performed on three carbonate rocks namely, Indiana limestone, Estaillades limestone and Edwards dolomites. Experiments are carried out using medical CT scanner and N2-water fluid system at high pressure. Drainage core floods are carried out by varying nitrogen fractional flow rates from 0 to 1. Residual trapping is obtained at the end of drainage cycle by water flooding of the core. These rocks are from three difference quarries. Indiana carbonate is from Salem Formation located in Indian, USA. Estaillades limestone is from Oppède quarry, France. Edwards dolomite is from Texas, USA. The data set contain medical CT Dry scans, nitrogen scans , water scans and scans at varying fractional flow of nitrogen; 1 readme file; 1 excel file; 27 zip files.

资助项目：ACT 优雅，项目编号 271498。针对通过碳酸盐岩心进行多相流排水的医疗CT扫描。在高压条件下，采用氮气和去离子水进行稳态排水多相流实验，以研究异质性对流体流动性的影响。在三种异质碳酸盐岩上进行核心洪水实验，包括印第安纳石灰岩、埃斯塔伊拉德石灰岩和爱德华兹白云岩。实验采用医疗CT扫描仪和高压氮水流体系统进行。通过调节氮气分流量从0到1，进行排水核心洪水实验。在排水周期结束时，通过水驱核心洪水获得残余滞留。这些岩石来自三个不同的采石场。印第安纳碳酸盐岩来自位于美国印度的塞勒姆组。埃斯塔伊拉德石灰岩来自法国Oppède采石场。爱德华兹白云岩来自美国德克萨斯州。该数据集包含医疗CT干扫描、氮扫描、水扫描以及不同氮气分流量扫描；1个README文件；1个Excel文件；27个ZIP文件。
