Slug tests data, analysis, and results at wells near the North Shore of Lake Superior, Minnesota

This dataset contains the original data, analysis data, and a results synopsis of 12 slug tests performed in 7 wells completed in unconfined fractured bedrock near the North Shore of Lake Superior in Minnesota. Aquifers tested include extrusive and intrusive volcanic rocks and slate. Estimated hydraulic conductivity range from 10.2 to 2x10-6 feet/day. Mean and median hydraulic conductivity are 3.7 and 1.6, respectively. The highest and lowest hydraulic conductivities were in slate and fractured lava, respectively. Compressed air and traditional displacement-tube methods were employed. Water levels were measured with barometrically compensated (11 tests) and absolute pressure transducers (1 test) and recorded with data loggers. Test data were analyzed with AQTESOLV software using the unconfined KGS (Hyder and others, 1994; 9 tests) and Bower-Rice, 1976 models (3 tests).This dataset contains the original data, analysis data, and a results synopsis of 12 slug tests performed in 7 wells completed in unconfined fractured bedrock near the North Shore of Lake Superior in Minnesota.

Data files include the original recorded data, data files transformed into a form necessary for AQTESLOV, AQTESOLV analysis files and results files, and a compilation of well information and slug-test results. All files are formatted as tab-delimited ASCII except for the AQTESOVE analysis and results files, which are proprietary aqt and PDF files respectively. For convenience, a Microsoft Excel file is included that contains a synopsis of the well data and slug-test results, original recorded, transformed, and plotted slug-test data, data formats, constants and variables used in the data analysis, and notes about each test.

本数据集涵盖美国明尼苏达州苏必利尔湖北岸附近非承压裂隙基岩中7口钻井内开展的12组段塞试验（slug test）的原始数据、分析数据及结果概要。本次试验涉及的含水层包括喷出型火山岩、侵入型火山岩与板岩。估算得到的渗透系数（hydraulic conductivity）取值范围为10.2至2×10⁻⁶英尺/天，其均值与中位数分别为3.7和1.6，其中渗透系数最高的样本取自板岩，最低的样本取自裂隙熔岩。
本次试验采用压缩空气法与传统位移管法开展，水位测量使用11台气压补偿式压力传感器（pressure transducers）与1台绝对压力传感器，并通过数据记录仪完成记录。试验数据采用AQTESOLV软件进行分析，分别应用非承压条件下的KGS模型（Hyder等，1994；对应9组试验）与Bower-Rice模型（1976；对应3组试验）。
数据集包含的文件类型如下：原始记录数据、适配AQTESOLV软件所需格式的转换后数据文件、AQTESOLV分析文件与结果文件，以及钻井信息与段塞试验结果汇编。除AQTESOLV分析文件（专属aqt格式）与结果文件（PDF格式）外，其余所有文件均采用制表符分隔的ASCII格式。为便于使用，本数据集还附带一份微软Excel（Microsoft Excel）文件，其中包含钻井数据与段塞试验结果概要、原始记录数据、转换后及绘图用段塞试验数据、数据格式说明、数据分析所用常量与变量，以及各组试验的相关备注。
