    What is multi-component seismic technology?

    It provides better subsurface characterization than conventional methods.

    How do P waves differ from S waves?

    P waves cause volume change, while S waves only change shape.

    What is the significance of shear wave polarization?

    It helps in understanding fracture orientation and density.

    What are the two major wave types in seismic data?

    Body waves and surface waves.

    What is the role of hydrophones in seismic data acquisition?

    They detect pressure changes in the water column.

    Why are S waves insensitive to fluid content in rocks?

    They propagate only in solids and do not change with fluid presence.

    What happens to P waves at subsurface interfaces?

    They can convert to S waves, creating converted waves.

    What is the purpose of multiple subtraction in seismic processing?

    To remove unwanted reflections and enhance data clarity.

    How does multi-component seismic improve fracture characterization?

    It utilizes both P and S wave data for better analysis.

    What is the impact of azimuthal coverage in seismic surveys?

    Wide azimuth coverage allows for better imaging of complex geology.

    What is the difference between common midpoint and common conversion point?

    CMP assumes symmetry in P wave reflection, while CCP does not.

    What is the significance of Young's modulus in seismic studies?

    It relates stress to strain in elastic materials.

    What is the effect of shallow gas on P wave imaging?

    It can obscure imaging by lowering P wave velocity.

    What is the benefit of using both geophones and hydrophones?

    They provide complementary data for better noise suppression.

    What is the role of surface wave analysis in near-surface characterization?

    It helps build accurate velocity models for subsurface layers.

    What is the purpose of receiver rotation in multi-component seismic?

    To resolve horizontal components into radial and transverse components.

    How does machine learning apply to multi-component seismic technology?

    It enhances data processing and interpretation capabilities.

    What is the challenge of using traditional streamer technology?

    It often provides limited azimuthal coverage in complex geology.

    What is the significance of stress and strain in seismic data interpretation?

    They are fundamental to understanding material behavior under load.

    What are the implications of using ocean bottom nodes in seismic surveys?

    They allow closer data acquisition to existing infrastructure.
