Question 4

What are seismic attributes?

Answer 4

• Any sort of measurement on seismic data
• Time
• Amplitude
• Frequency
• Loop-width
• Attenuation etc etc
• Measured over:
• Windows
• Adjacent traces
• Single points on amplitudes
• Edges etc etc

Question 5

Two main types seismic attributes

Answer 5

1. Surface based
   Extracted along or nearby an interpreted horizon
   2.Volume based
   Calculated from a window, between horizons, or in a window around a surface

Question 6

The Forward steps

Answer 6

Section => pv => Reflect coeff => Typical wavlet CONVOLUTION => SEIS TRACE

Question 7

The Inverse steps

Answer 7

SEIS TRACE => DECONVOLVE AVEC WAVELET => Intergration of seis trace in pv (impédence)
=> interpret Earth modele
