LBr-1 is a depleted oil field in the Czech Republic where a small-scale storage pilot is in preparation through the REPP-CO2 project. The reservoir, Miocene sandstones at ~1100 m depth hydraulically connected to an aquifer, is a typical example of a hydrocarbon-bearing structure in the Vienna Basin, one of the oldest hydrocarbon provinces in Europe. The site will be used to i) assess the potential for unwanted migration and/or leakage through abandoned boreholes and faults and ii) investigate reservoir behaviour in the presence of
CO2 and hydrocarbons, including possible mobilisation of hydrocarbons and use of CO2 for Enhanced Oil Recovery (EOR).
