What is the primary objective of seismic interpretation in exploration?
Seismic interpretation helps identify subsurface geological structures and potential hydrocarbon reservoirs.
Which type of seismic wave is most commonly used in reflection seismic surveys?
Reflection seismic surveys primarily use P-waves due to their ability to travel through various layers and return clear subsurface images.
What is the function of a geophone in seismic surveys?
Geophones detect ground motion and convert seismic energy into electrical signals for data analysis.
Which technique helps improve image clarity in seismic interpretation?
Migration improves the clarity of seismic images by correcting for the spatial displacement of reflection points.
What is a seismic section?
A seismic section is a visual representation of subsurface structures generated from seismic reflection data.
How does 3D seismic data benefit exploration?
3D seismic data provides a more detailed and accurate view of subsurface structures compared to 2D data.
