What’s New and Where to Find It in V6.5

Q2/3 2016

V6.5 At A Glance (December 2016)• Restack data while you do velocity analysis (CVA)• Manage Projects using SeisCat• iMage platform on the Launcher• iMage platform extended to include Octave deghosting• New module to add SPS to seismic data in a flow (ADDSPS)• Easier QC/Update of existing velocity picks (CVA)• 6 month release cycle with monthly “beta” releases

Restacking in CVA Velocity AnalysisWhat it does: Creates a new stack panel with the current velocities

Where to find it: The RESTACK button on the main CVA window

• Restack creates a new “panel” display• Restack panel updates live while you pick• Compare with original stack • Stack is automatically saved for future QC• Pick better velocities, faster

Manage Projects Via SeisCatWhat it does: Replaces some of the “project” functions on the Launcher

Where to find it: Right Click in the “Project” pane of SeisCat

• Archive existing projects • Restore project archives • Create new projects • Register projects to the repository• Show project details

Image Platform On LauncherWhat it does: Easier Access to the Image Suite

Where to find it: On the Flows tab of the Launcher

• 3DSRME• Octave Broadband Deghosting• Anisotropic 3D PreSTM• STITCH 5D Interpolation• Multi-SEGY file input

Image Platform ExtendedWhat it does: Octave Deghosting now in the Image Suite

Where to find it: In the Image Platform

• Runs from multiple SEGY files• Checks data format and grid automatically• Automatic default parameters from data • Run interactively or on queues• Integrated logging window• Progress bar and completion estimates

Read SPS Data in Batch ModeWhat it does: Updates trace headers with land survey data in a flow

Where to find it: ADDSPS Module

• Batch process 3D swaths • Use Bin3D to create CDP numbers• MAKEGEOM to build geometry database• Field data to refraction-statics-ready in one step

Velocities : Easier EditingWhat it does: Use left Mouse Button to “Rubber Band” delete a trend

Where to find it: In the CVA tool, Semblance Picking

• Hold left mouse button and drag over incorrect picks• Picks will be bulk deleted• Remove incorrect trends rapidly when QCing

And if you missed it…

V6.4 At A Glance (June 2016)• New residual moveout (RMO) capability • New slant / variable cable deghosting technology • New curved ray/anisotropic 2D/3D PSTM• iMage Platform standalone extended : 3DSRME, 3DPSTM• New application for defining 3D grids • Support for “right handed” 3D geometries • Easier parallel processing • Improved 3DSRME performance • 7 month release cycle with monthly “beta” releases

Residual Moveout : CVA and RMO

PreSTM• Run IMAGEK2T or IMAGEK3T• Use regular or anisotropic (4th order mode)

CVA• Read flattened gathers directly in to the CVA velocity package• Pick residual moveout on semblance, gathers or stacks

RMO• New RMO module used with flattened gathers• Applies true residual moveout using old and new fields

Octave : slant cable deghostingWhat it does: Removes the marine ghost notch for variable tow-depth cables

Where to find it: The OCTAVE_N module

• Shot-ensemble deghosting• Reads tow depth from a trace header• Uses planar wave solution• Runs in parallel• Constant depth mode available• Delivers on high resolution data (SI <1ms)

Curved Ray Anisotropic PreSTMWhat it does: better long offset imaging by including “horizontal” velocities

Where to find it: New parameters in the imageK2T and imageK3T modules

• Pick 4th order moveout in CVA• Run curved ray anisotropic preSTM• Pick 2nd order residual moveout in CVA• Apply with the new RMO module• Better images, faster and easier workflow

Image Platform ExtendedWhat it does: 3DSRME, 3DPreSTM now added to Image

Where to find it: In the Image Platform (type gc_image at the prompt)

• Runs from SEGY or HDF5• Checks data format and grid automatically• Automatic default parameters from data • Run interactively or on queues• Integrated logging window• Progress bar and completion estimates

New 3D Grid ApplicationWhat it does: Define and edit a 3D geometry; X,Y Inline,Crossline

Where to find it: On the launcher : Display 3D Geometry

• Create, view or edit 3D grid files• Flip left/right handed defintions• Simple interface and display• Calculate X,Y from inline/crossline• Calculate inline/crossline from X,Y

Geometry : LH/RH GridsWhat it does: More flexibility in geometry definitions

Where to find it: In Geometry, on the 3D Geometry Display Tool

Easier Parallel ProcessingWhat it does: Specify the number of cores on job submission, not in the job

Where to find it: MPISTART/END loops, job submission

• No “Nodes” parameter in MPISTART• MPICH version (2/3) auto-detected• Defined how many core to use when you run• Support for SunGridEngine and Torque queues• Configurable for other load management systems
