Ask Andy! Can you explain how to effectively remove linear noise using a Tau-P domain mute? Tau-P domain muting is a powerful tool for removal of coherent linear noise such as refractions and direct arrivals, allowing for more open outer mutes.
Tau-P domain processing can be a very powerful option for removing linear noise or attenuating short period reverberant multiples. As such, it is important to optimize the pre-processing and the actual Tau-P transform itself in order to make sure you achieve the best results possible from Tau-P domain processing.
New Software Release from GLOBEClaritas Version 7.3 with new features including the Tomographic Refraction Statics and ViewStatics applications as well as a new and improved interface for Geometry app.
Typically, Marine raw seismic data would best be described as mixed phase, being neither Minimum or Zero phase. Ideally, your data will come with a recorded or modeled farfield source signature, for modern acquisition it will likely be modeled by a package like Gundalf or Nucleus while vintage data may use a farfield hydrophone to record the signature.
Ask Andy: Is there a way to interpolate irregular land datasets in GLOBEClaritas? Yes! There are two methods using GLOBEClaritas - the MISSING/RUNMIX approach and using the OFFREG/DEOFFREG method.
The GLOBEClaritas team is pleased to deliver another quality software release to our users, with significant improvements to the user experience and the third under the Petrosys banner.
Ask Andy - Our GLOBEClaritas expert about how you can apply CDP geometry to a 2D Marine line in Claritas. This is a key stage of the processing sequence and in the Claritas software we have a number of options.
Ask Andy our expert on GLOBEClaritas, about importing velocity files. SegY formats can be directly read by the GLOBEClaritas NMO module and others but if your dataset is in another format read on to find out how to GLOBEClaritas handles those too.
