What is seismic processing?

3

Echography at scale

4

Acquiring geophysical data

5

• 1-10Ks of square km

• Months to years

• 1000s of people

• 10s of PB raw data

Raw seismic data

6

• 100s TB to 10s PB

• Several trucks of tapes

• 1000s of samples per trace

• 100k-10s millions of traces per sqkm

Single

Recorded

“Trace”

Traces on a single line (on-shore)

“Customized” processing sequence & technology

7

Reformat from SEG-Y format field data

Geometry assignment

Elevation Statics

Spherical Divergence Correction

Statistical de-spike for high amplitude noise bursts

Aliased linear noise attenuation

Adaptive Ground-roll Attenuation

Guided Wave Removal with primary protection

3D Random noise attenuation with primary protection

Statistical de-spike on randomized

1st pass residual statics

Surface Consistent Deconvolution

Surface Consistent Amplitude Correction

COV denoise, with primary protection

3D regularisation

PSTM

Structurally-consistent dip filter

Linear RADON

Subsurface Imaging Business Line

A large organization

14

• #1 in seismic processing

• 26 processing centers

• Around 2000 people

• Above 150 clients

• In-house software

• 100s of researchers

• Even more developers

Our HPC infrastructure

15

• 10 000s cluster nodes

• Very high density

• Intel single-socket chips

• Significant local storage

• Ethernet interconnect

• 1000s GPU servers

• Very high density

• Very fast local storage

• Ethernet interconnect

• 100s PB storage

• Raid 6 with distr. parity

• Low-cost drives

• In-house architecture

• Very good fault-tolerance

Our processing software: geovation

16

• 10s M lines of code

• 500+ processing batch modules

• 10s interactive applications

• Job scheduler

• Storage middleware

• Cluster management tools

17

Some highlights of our HPC infrastructure

Strategic partnership: AMD example

18

Evaporative cooling in the UK

19

PUE is 1.06

Oil immersion

20

50+ % electricity savings

PUE reduced to 1.02

• Large-scale GPU farms are complex to manage

• Oil immersion adds its own complexity

• Vendors now have oil-ready GPU servers

• Oil immersion allows higher power density

Conclusion

Interesting challenges

Depressed oil & gas market

Nonetheless managing a fairly significant HPC infrastructure

Interesting technological projects

Continue to look for top talents!!
