The picture shows about seismic wave.

Please choose the correct answer from the left to the right.

• Shear Wave - Surface Wave - Primary Wave

• Surface Wave - Shear Wave - Primary Wave

• Primary Wave - Shear Wave - Surface Wave

• Primary Wave - Surface Wave - Shear Wave

Why is seismic imaging not vertically as detail as well data?

• Seismic has lower resolution than well data

• Seismic in time domain while well data in depth domain

• Seismic has more noise than well data

• Seismic has higher frequency to solve the thin lithology

• Trap & Seal

• Source

• Migration

• Basement

How we can get the velocity data to evaluate subsurface velocity change?

• seismic interpretation data

• checkshot or sonic data

• RMS velocity from seismic processing

• well marker data

What is the correct statement based on this picture?

• Input data can identify thin reservoir

• Colored Inversion has lower frequency than input data

• Colored Inversion has higher frequency to define thin reservoir better than input data

• Colored Inversion is not applicable to identify thin reservoir

Which one is the incorrect statement?

• Seismic methods utilize elastic energy to create an image of the subsurfcae

• Seismic always correct to provide subsurface image solution

• Seismic has limitation both vertical and horizontal resolution

• Seismic data must calibrate to well data
