Small-scale stimulations investigating Geobiology
A research team led by Cara Magnabosco, professor in Geobiology, is conducting an experiment today to investigate the effect that hydraulic stimulation has on microorganisms inhabiting the Bedretto reservoir. The team will inject relatively small volumes of water (33 liters per minute) into one interval, closely monitoring the process. Special attention will be paid to how bacteria respond to water flow, pressure and induced seismicity.
Safety is a top priority, and the team follows a well-established protocol. If predefined safety thresholds in magnitude or vibration are reached, the injection is halted, and bleed off is initiated. The BedrettoLab team has significant experience in conducting such stimulations, making them well-prepared for this study.
Similar stimulations with geobiological focus will be repeated in one week. Overall, this research has the potential to provide valuable insights into the impact that hydraulic stimulation has on microorganisms in the reservoir.
