Article1 - Marine multicomponent seismology

Question 1

decimation

Answer 1

subset

Question 2

Specify and advantage of multi-component data interpretation when compared to conventional 1 of 2 component P wave technology

Answer 2

Records both P and S waves with enough data for interpolation.
Provides more complete interpretation of reservoir properties than P wave (1 or 2 component)

Question 3

1 C (L,M)

Answer 3

Receiver Type - Hydrophone

Recording Direction - P wave

Question 4

2-C (M)

Answer 4

1 p-wave hydrophone

2 vertical axis geophones

Question 5

3-C (L)

Answer 5

1 vertical geophone

2 horizontal geophones (orthogonal to one another)

Question 6

4-C (M)

Answer 6

1 vertical hydrophone (Swave)
1 vertical geophone
2 horizontotal geophones

Question 7

Most imp properties of P and S waves

Answer 7

P waves travel 2x faster than S-waves
P waves are affected by matrix and pore spaces
S waves are affected by matrix
