"State of the Art" Technology
PGS' Technology division has produced a number of powerful and innovative demultiple techniques. Exciting recent developments have created a portfolio of data-driven demultiple algorithms that are suited to a wide variety of geometries & geology.
In the 3-D SRME case, the PGS HD3D acquisition technology will provide the optimal platform for processing success - particularly when complemented by an overlap shooting strategy.
Diagnostic Analysis & Modelling
PGS can use sophisticated modelling and processing tools to analyse whether a particular event on the data is likely to be primary or multiple energy.
Expertise & Efficiency
PGS’ expertise and efficiency in demultiple processes is based upon four key elements:
-
A learning organisation – A web-based ‘resource-bank’ system is used to disseminate knowledge and expertise
-
Optimised and standardised job flows
-
Pre-defined testing strategies
-
Close interaction with the project management database – KnowledgeNet
Interactive QC & Visualisation
PGS’ high-end visualisation system, holoSeisTM, is routinely used to provide detailed and interactive QC of demultiple processes.
Use of PGS' holoSeisTM visualization system to verify the success of
SRME multiple removal.
