Dataset of the Brine Injection at the CO2 Storage Pilot Site Ketzin, Germany

The Ketzin pilot site has been the longest-operating European onshore CO2 storage site. Between June 2008 and August 2013, a total amount of 67 kt of CO2 has safely been injected into a saline aquifer. The reservoir consists of 630 m to 650 m deep sandstone units of the Stuttgart Formation of Upper Triassic age. These were deposited in a fluvial environment (Förster et al., 2010). A sequence of about 165 m of overlaying mudstones and anhydrites is sealing the storage complex and act as caprock (Martens et al., 2012).
The research and development programme at Ketzin is among the most extensive worldwide in the context of geological CO2 storage (Giese et al., 2009). Research activities have produced a broad data base and knowledge concerning the storage complex at Ketzin itself but also CO2 storage in general (Liebscher et al., 2013; Martens et al., 2011-2014; Würdemann et al., 2010; Schilling et al., 2009).
This publication compiles the operational data (flow rate, cumulative mass, density, injection temperature, electrical conductivity and in-well pressure data) recorded during a field experiment on brine injection at the Ketzin pilot site during October 2015 to January 2015. Anyone should feel free to make use of the published data for any ethical purpose (civil use) – for example for process modelling and engineering.

Ketzin试点场地是欧洲运营时间最长的陆上二氧化碳封存场地（CO₂ storage site）。2008年6月至2013年8月期间，累计6.7万吨CO₂被安全注入咸水含水层（saline aquifer）。储层由上三叠世斯图加特组（Stuttgart Formation）深度为630至650米的砂岩单元构成，形成于河流环境（Förster等，2010）。覆盖其上的约165米厚泥岩与硬石膏层序密封了封存复合体，充当盖层（caprock）（Martens等，2012）。

Ketzin的研发项目是全球范围内地质二氧化碳封存（geological CO₂ storage）领域最广泛的项目之一（Giese等，2009）。研究活动不仅产生了关于Ketzin封存复合体的广泛数据库与知识，也为二氧化碳封存的总体研究提供了支撑（Liebscher等，2013；Martens等，2011-2014；Würdemann等，2010；Schilling等，2009）。

本出版物汇编了2015年10月至2015年1月期间在Ketzin试点场地开展的盐水注入现场试验所记录的运行数据（包括流量、累计质量、密度、注入温度、电导率及井内压力数据）。任何人都可出于任何符合伦理的目的（民用）自由使用已发布的数据——例如用于过程建模与工程领域。
