Survey Design Phase Two: Optimisation

The provisional design from Phase One is refined to incorporate details such as source and receiver arrays, infill planning and methods of weathering control. Any field trials which were conducted following Phase One are analysed using proprietary software to measure signal to noise ratio and bandwidth.  The data processing aspects are analysed in detail, so that the combined responses of the acquisition and processing systems will be optimised in the final data volume. Pre-tender enquiries may be conducted with contractors to establish the availability of any unusual field equipment. The result is a detailed set of specifications and procedures for the acquisition, field QC and processing of the survey including:

Survey Design Software

Our specialised software has been developed through 3D design projects covering every type of terrain and geological objective:  

• Land and marine source modelling
• Template design and bin attribute analysis
• Polar directivity patterns for source and receiver arrays, stack response, 3D DMO and PSM responses
• Tidal analysis and feathering prediction
• Survey planning on satellite images and digital elevation maps (deviations, exclusion zones, undershooting, etc.)
• Elastic modelling including multi-component VSP, OBC, impulsive and vibratory sources
• AVO modelling
• Processing and signal to noise ratio analysis of field trials
• Acquisition footprint modelling: 3D volume simulation from 2D seismic or elastically modelled data
