unrecognized SEGY headers
In GLOBE Claritas, standard format SEGY files are read in using the READSEGY module (and written out using the WRITESEGY module), not DISCREAD. [list][li]READSEGY reads SEGY formatted input files from disc or tape, and passes traces to downstream modules in the Claritas internal format.[/li] [li]READSEGY must be unique in any given seismic job, and must be the first module in a job stream.[/li] [li]READSEGY can manipulate the trace headers as the data is read in. Usually at least two Claritas-sp... 5 years ago |

unrecognized SEGY headers
Hi, I encounter some problems linked to my input SEGY files. They are clearly read by Globe Claritas but no headers are recognized except the numbers of samples and the sample rate. However, when plotting some shots I have checked and noticed that amplitude features of every traces are correct. Someone knows where the problem can come from? 5 years ago |

V6-5 beta release - 19th August 2016
On the 19th of August 2016 we completed another release sprint of the development version of GLOBE Claritas (V6-5) and were able to provide a download for the latest beta release to our Linux clients. This is the second of 6 to 7 anticipated beta releases before the full V6.5 release at the end of this year. Some of the features in this beta release include:- - Bulk deletion capability added to CVA - On the ISOVELS window the user can rubber band around a number of picks across single or mul... 3 years ago |

V6.10 3D Land Tutorial
An updated version of our 3DLand tutorial is now available from the GLOBClaritas team for users, extends the topics covered in the tutorial beyond just the Geometry and Refraction statics that the original tutorial covered to include, noise attenuation. decon, residual statics and imaging. Contact claritas.support@gns.cri.nz for the download information. 5 months ago |

velocity picking for statics
Is there any other info from the survey area you can use to define V0 on the velocity model? If so use this to create an approximate value for V0 then fix the V0 layer in the velocity model and let the refstat application work on V1 (and on V2, if you decide to add another layer). If you have no way of estimating V0 the other option would be to not carry out refraction statics and try to resolve with residual statics. 5 years ago |

velocity picking for statics
Hi, my 2D onshore seismic data have been acquired with a minimum offset set to 24 meters. Thus the direct wave corresponding to the propagation in the thin weathering layer is not recorded and the first arrivals are almost all refracted waves. In the vels scatter window, the first velocity cluster that I migth pick is not supposed to be the V0 but the V1. What alternative in Claritas would you advice me to ensure good inversion results. 5 years ago |
