Which of the following processing techniques is most effective in attenuating 'ground roll' in land seismic data, and why is its application crucial for improving data quality?
Question 2
In a reflection seismic survey, what is the primary purpose of applying 'spherical divergence correction' during data processing?
Question 3
Consider a seismic reflection from an interface where the acoustic impedance of the upper layer is $Z_1 = 3.5 \times 10^6 \text{ kg/(m}^2\text{s)}$ and the lower layer is $Z_2 = 5.0 \times 10^6 \text{ kg/(m}^2\text{s)}$. Calculate the reflection coefficient $R$ at this interface.
Question 4
When interpreting seismic data, what is the significance of identifying a 'gas chimney' feature, and what does it typically indicate about the subsurface?
Question 5
Which of the following acquisition parameters in a 3D seismic survey has the most direct impact on the spatial resolution in the horizontal direction (i.e., the ability to resolve features laterally)?
