Version 6.2 introduces several new features including 3D surface-related multiple estimation, a new shot/receiver basemap plotting tool, and improved seismic display options, along with 212 bug fixes. Key enhancements include the ability to revert to original geometry after regularisation, faster workflows for swell noise removal and 2D SRME, and a new Condor application for visualizing seismic data. The updates facilitate better user control, efficiency, and accuracy in seismic data processing.

1. What’s New and Where to Find It in V6.2
Q1 2015

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
