Processing of magnetotelluric data for monitoring changes in electric resistivity during drilling operation

  title={Processing of magnetotelluric data for monitoring changes in electric resistivity during drilling operation},
  author={N. Haaf and E. Schill},
Long-term magnetotelluric monitoring of different injection and production experiments at the Rittershoffen geothermal site in Alsace (France) provided a first continuous data set over several month, covering the end of drilling phase of GRT2 (Abdelfettah et al. 2018), mostly, production from, but also injection into this well, injection into GRT1 and a circulation experiment. Transfer functions showed particular variation pattern for different operations, i.e. an increase in uncertainty… Expand
