    Microseismic to CCS is what seismic to E&P?

    Backdrop - carbon capture sequestration (CCS) is emerging as high-impact opportunity for geologists to horn their skills.

    Recently I heard the pitch from Microseismic Inc (Duncan) that permanent life-of-field EM + seismic array is prime for CCS, e.g., monitoring and tracking where the carbon plumes are at all times.

    Premise (as I understand) -

    1) Electrical impedance change > Δ seismic impedance in CCS (more CO2)
    2) Increase with moisture absorption (in general from literature search*)

    Q1: how do we think about this - another inversion problem for geoscientists to tackle?

    Q2: can we put ChatGPT to good use - more powerful search and discovery to distill a shortlist of most favorable CCS spots?

    Love to hear your thoughts.

    *Google "electrical impedance" and found electrical impedance tomography (albeit from biochem)
