    Study Notes

    The text discusses seismic exploration methods, focusing on the seismic reflection method. It covers topics such as single and multiple horizontal reflectors, seismic velocities, and dipping layers. Key points include:

    1. Seismic exploration methods include seismic reflection and seismic refraction.
    2. Seismic reflection is the most widely used method.
    3. Raw data can be processed by computers to create an image of the subsurface.
    4. The seismic reflection method assumes that the media is layered.
    5. The position of reflectors can be determined by measuring travel time at the shot point.
    6. The normal moveout (NMO) is the time difference between the arrival at the shot point and the arrival at a specific distance.
    7. The RMS velocity can be used to estimate the interval velocity down to a certain depth.
    8. Dix's formula can be used to convert measured RMS velocities to real interval velocities.
    9. Dipping layers require the use of dip moveout to estimate the dip angle.
    10. The dip angle can be estimated by measuring the travel time difference between two geophones at both sides with the same distance.
