2. What’s new in V6.2
• 3D surface related multiple estimation (3D SRME)
• Ability to revert to original geometry after regularisation
• New shot/receiver basemap plotting tool
• New tool for viewing and comparing seismic
• Better seismic displays with more analysis options
• Improved “angle gather” generation and muting workflows
• Speed ups : swell noise removal, 2D SRME
• Total of 212 bug fixes and updates in 7 months
• Beta releases shipped every 4 weeks
3. 3D Surface Related Multiple Estimation
What it does: Accurately models seafloor multiples in 3D marine data
Where to find it: A new module, SRME3D, from the XJSE job flow builder
• Runs in parallel
• Can read in multiple files (sail lines)
• Fast, accurate full 3D modelling
• User control over output range
• Requires no upfront interpolation
4. DEOFFREG
What it does: Lets you go back to the original offsets after applying OFFREG
Where to find it: A new module, DEOFFREG from the XJSE job flow builder
• Interpolate land data to unwrap aliased noise
• Apply Tau-P or FK methods to remove noise
• Revert back to original shot/receiver locations
• Faster and easier alternative to 3D cross-spread methods
• Marine data : recover original offsets after 2D SRME
5. New CONDOR Application
What it does: Displays the shot and receiver locations in an HDF5 format file
Where to find it: On the Launcher
• Zoom, pan and colour controls
• Allows plotting to A3/A4 (PNG)
• Will be extended to replace Geometry
6. New SEISVIEW Application
What it does: Displays one or more seismic files, overlaid as panels
Where to find it: On the Launcher, Select files in SeisCat and right click
• Compare pre/post stack data
• Data needs to be in same order
• Can manage “gaps” in datasets
• Compare HDF5, SEGY or CSEGY
• Compare 3D surveys (via CUBE)
7. XVIEW Improvements
What’s new: New filter and autocorrelation panels
Where to find it: Utilis Menu on XVIEW displays
• Create filter panels with one click
• Append autocorrelations with one click
• Improved default plot scaling
• Compare frequency spectra on one panel
• Better defaults for “remote” displays
8. Angle Workflows Easier
What’s new: Create angle gathers and mutes more efficiently
Where to find it: ANGLE, ANGLETIMES and HDRMUTE modules in XSJE
• Can read velocity traces (from VELTRACE)
• Can have more than 4 new mutes created
• More accurate calculations (no rounding)
• Can use “extended” trace headers
• Easier to use external (SEGY) velocities
9. Marine Workflow Faster
What’s new: Swell noise removal and 2D SRME speeded up
Where to find it: DUSWELL, SRME2D modules in XSJE
• DUSWELL speeded up by x5 to x9 times
• SRME2 and SRME2_MPI replaced
• SRME2D up to x700 faster than originals
• Achieved using optimisations developed
for the 3D SRME
