Introduction Breakout 4

“Significant Issues Managing Seismic Data”

1th October 2014

NDR 2014

Significant Issues Managing Seismic Data

• Seismic data on the NDR agenda

• Last 40 years techniques to produce seismic data have

developed

• Seismic data is related to cutting edge technology


• Seismic data is a very important data type

• Seismic data contains a lot of subsurface information

• Understand subsurface

• Input to decide to drill a well

• Always a need to understand the subsurface

• Seismic data will stay in the list of data types of an E&P data

manager


• ....... that can cause some significant headache in the mind of a

data manager

• How to keep track of the latest geophysical techniques?

• How to deal with the very large seismic volumes?

• How to deal with legacy data

• How to QC seismic data before storing the data in the NDR?


• Besides, seismic data is not a really easy to understand

• Many processing steps are required before a person can discover

geological structures in a seismic profile


• Breakout session to discuss significant issues that you face

during management of seismic data

• This breakout has got 3 simultaneous sessions

• Interested in seismic data choose one of the 3 session

Feedback on day 4

Some seismic

“Stacking”


• In total 30 participants in session A & B

• 12 participants work directly for NDRs

• 24 participants attended session A “Issues concerning seismic

data intake”

• 6 participants attend session B “Issues concerning seismic data

delivery” & “Issues applying seismic standards”

Feedback Breakout nr. 4 Session A - “Issues concerning seismic data intake”

• Participants introduced themselves, 80 % have a direct relation

with seismic data

• Afterwards we did a small brainstorm which to identify topics for

this session

• List of 6 topics

• We identified the top 3 most important topics

• We stopped 10 minutes later than planned


List of topics

A. How to define the quality of the seismic data

• When is your seismic data set complete

• When do you have good seismic data

B. How to deliver seismic data to the NDR

• Media

C. Spec (multi client) survey policies



• How do you know if seismic data is acquired in a NDR’s

jurisdiction

• Almost every NDR knows on forehand that a seismic survey

will take place

• Need to report their plans regarding seismic acquisition

• Need to have a licence (difference in spec data and licence

data)

• NDRs store the announcement (with ID) and NDRs that

only store the seismic data itself



• Completeness of a seismic dataset (inquire processing report)

• Strong need for a simple checklist for seismic data intake

• Checklist for :

• Seismic acquisition

• Pre stack data intake

• Post stack data intake

• Almost every NDR knows on forehand that a seismic survey will

take place



• Topics for the checklist for Seismic acquisition

• unique ID for a seismic survey

• Licence name & survey name

• Date of survey, needs a good definition

• Completion date

• Date that seismic data is given to operator

• Etc.

• Important data: navigation and seismic signal data

• Important docs: observation logs, acquisition report


A. When do you have good data

1. NDRs are doing QC of seismic themselves

2. NDRs that do not alter seismic data responsibility of operator

3. NDRs in transition, moving from 1. 2.

• Good description of quality (available on forehand for the

operator)

• Provide QC tooling to operator

• Penalties when data has got a bad quality

• Inform public on results of QC jobs of operators


B. How to deliver seismic data to NDR

• NDR are using different media for transport of data

• Some of the NDR prescribe which kind of media to use

Off line | Near line | online storage of seismic data

• The solution you pick depends on your requirements and

available budget

• Other industry sectors have most of the time another business

case

Feedback Breakout nr. 4 Session B - “Issues concerning seismic data delivery

and applying seismic standards”

• Legal framework of what can be delivered

Sub setting / cutting of pre-stack and field data

• Ensure regulations / guidelines cover

what is delivered

how it can be delivered (include formats available)

how much it will cost

• Consider data security

Ensure T&C including confidentiality are signed off prior to delivery

Encryption of data on disk to ensure data only gets to entitled person

Feedback Breakout nr. 4 Session B - “Issues concerning seismic data delivery

and applying seismic standards”

• QC output

Check what has actually been written to media

Use simple checksum prior to sending – client checks on receipt

Track the delivery through transmittals and courier tracking system

• Charging

Charge for value added service e.g. delivery of workstation ready
