The Ketzin pilot site, led by the GFZ German Research Centre for Geosciences, is Europe's longest-operating on-shore CO2 storage site with aim of increasing understanding geological in saline aquifers. Located near Berlin, an situ laboratory anticlinal structure Northeast Basin. Starting research within framework EU project CO2SINK 2004, Germany's first and fully use since injection began June 2008. After 39 months operation, about 53,000 tonnes have been stored 630–650 m deep sandstone...
The CO2SINK Integrated Project aims at in-situ testing of geological storage CO2 in a saline aquifer. A field laboratory is developed with one injection well and two observation wells (50 m 100 distance). Focus the project on monitoring fate injected using broad range geophysical, geochemical microbiological techniques. Injection depth approximately 650 started end June 2008 arrival has been determined nearer as expected predicted after an amount 531 t CO2.
At Ketzin, located west of Berlin, the GFZ German Research Centre for Geosciences operates Europe's longest- running on-shore CO2 storage site. The Ketzin pilot site has been developed since 2004 and comprises three wells to depths 750 m 800 one shallow observation well, an injection facility permanently installed monitoring devices. Since June 2008, is injected into 630 650 deep sandstone units (Upper Triassic Stuttgart Formation) in anticlinal structure Northeast Basin. Until mid May 2012,...
Numerical simulations of CO2 migration for the period June 2008–December 2011 were performed based on a unique data set including recently revised static geological 3D model reservoir formation Ketzin pilot site in Brandenburg, Germany. We applied industrial standard ECLIPSE 100 and scientific TOUGH2-MP simulators this task implemented workflow to allow integration complex geometries from Petrel software package into TOUGH2-MP. Definition near- far-field well area allowed us apply suitable...
Abstract Clastic-dominated (CD-type) deposits contain a significant proportion of the global resources Zn, Pb, and Ag, include some largest that formed through subseafloor replacement. Mineralization textures in these can be highly variable, physical properties control are poorly defined. The style dissolution carbonate units described by dimensionless parameters (Péclet Damköhler numbers) represent fundamental reacting flow systems. Using reaction transport modeling CD-type deposit, this...
It is societal consensus that adequate and reliable supplies of affordable resources need to be obtained in environmentally sustainable ways [1]. The prevailing view the scientific community large amounts carbon dioxide (CO2) from atmosphere highly radioactive waste must disposed safely - kept away human habitat for a very long time. In regard, studies on natural processes extend over periods help understand long-term behaviour deep geological repositories. You can't carry out experiments...
The resource demands for the ongoing energy transition require increased exploration metal deposits. Clastic dominated (CD-type) deposits are an important target in this search because of their size and high grade. To narrow down CD-type deposits, it is to understand how they formed. One proposed formation mechanism these sedimentary exhalative (SEDEX), which fluid discharge from vents resulting stratiform sulfide precipitation on seafloor. Alternatively, has been suggested that can form...
Opalinus Clay is chosen as host rock for the deep geological disposal of nuclear waste in Switzerland and also being considered Germany. The underlying Staffelegg Formation comprises potentially water-bearing layers. To investigate hydrogeological setting these two formations at Swiss Rock Laboratory Mont Terri bore holes have been drilled framework HS-Experiment (Hydrogeological Survey). 58 m long BHS-1 starts Lower Shaly facies Clay, crossects entire formation ends Triassic Klettgau...
In this contribution the influence of spatial variability on uranium diffusion in clay is investigated by means 2D reactive transport simulations at host rock scale. The Opalinus Clay Mont Terri underground laboratory displays three main facies: a sandy and carbonate-rich facies, with porosity ranging from 6% to 14%, shaly facies 10% 25%. Geostatistical unconditional were generated different variogram parameters (correlation length, anisotropy variogram, ratio) matching available ranges for...
Waiwera is a small coastal village with 50 °C warm geothermal reservoir of 400 metres thickness directly underneath [1-2]. Hydrogeological models support water management by providing insights into sustainable extraction from the reservoir. We analysed system in several studies over past decades, mainly last ten years [3-12].Geothermal waters at originate rainwater percolating downward and heating background gradient. The fed along fault zone located base New radiocarbon...
The pilot study at the Ketzin site close to Berlin (Germany) aims in-situ testing of geological storage CO2 in a saline aquifer. Following characterization and drilling one injection well two observation wells, field laboratory has been fully use since started June 2008. After years operation, about 36,000 tons have injected. This paper presents key results from second year interdisciplinary monitoring concept frame European project CO2SINK (CO2 Storage by Injection into Natural Saline...
The quality of groundwater resources in the Pra Basin (Ghana) is threatened by ongoing river pollution from illegal mining. To date, there are very limited data and literature on hydrochemical characteristics basin. For first time, we provide regional surface water to gain insight into geochemical processes for drinking irrigation purposes. We collected 90 samples (rivers) (boreholes) analysed them their chemical parameters. performed a assessment using conventional rating indices...
To assess the long-term reservoir stabilisation at Ketzin pilot site (Germany), contribution of four CO2 trapping mechanisms (structural, residual, dissolution and mineralisation trapping) was determined by numerical modelling. In first step, dynamic flow simulations were undertaken using a simulator. The second step comprised batch applying geochemical Coupling between both simulators achieved time-step dependent integration water saturation calculated in simulations. After simulation time...
