RadExPro is flexible, stateofart processing package, suitable for HR/UHR marine data processing, land shallow seismic data processing (refraction, reflection, MASW and VSP), as well as largescale data QC, including RealTime and fasttrack processing.
Nearsurface land data processingRadExPro is fully capable for shallow structure imaging of both 2D and 3D land seismic reflection surveys with any type of source – sledgehammer, weight drop, guns, vibroseis and others.
Set of available algorithms includes refraction statics computation; crooked line CDP binning; linear and random noise attenuation algorithm’s, including 3D filters; SCAC; deconvolutions; auto statics routines; interactive velocity analysis; horizonbased velocity analysis; pre/post stack migrations.
Seismic refraction surveys are widely used for shallow seismic engineering applications. Timedelay and GRM (General Reciprocal Method) methods are implemented in RadExPro.
RadExPro provides fast and convenient automatic first break picking tool of seismic gathers to be used for further refraction analysis. All results are stored in the database and can be quickly accessed. Refraction horizons building process is fully interactive, which allows one to control the entire process from the very beginning up to the final image. This results in avoiding pitfalls during the processing and building the most relevant subsurface structure.
Multichannel analysis of surface waves utilizes Rayleigh wave dispersion properties to build Vs (shear wave) velocity profile up to 30 m depth for various geotechnical purposes. Ground roll strength on typical sledgehammer seismic record allows one to use its energy for MASW. General procedure for MASW processing includes dispersion curve calculation, fundamental and higher modes picking, followed by inversion. RadExPro has a dedicated MASW routine with userfriendly interface, which allows to perform all steps in a row up to final Vs section.
VSP and crosshole data processing requires efficient and sophisticated processing flow. RadExPro seismic software provides all necessary algorithms for multicomponent data processing – hodogram analysis, 2C/3C component orientation, wavefield separation, velocity modelling, corridor stacking and well tie to reflection seismic data.
Highresolution marine seismic processingRadExPro has a complete set of algorithms for shallow marine seismic data processing, including modern denoising algorithms, static corrections, designature techniques (debubbling, adaptive deghosting, signal shaping), multiple removal (SRME), adaptive subtraction, 3D regularization, prestack migrations (PSTKM). Many routines are specially developed and adapted to high resolution data processing.
Largescale seismic surveysInfield data quality control is a standard procedure during oil and gas acquisitions, which typically includes position data quality checks, seismic data quality control and their relationship. RadExPro has various instruments, including data and spectrum analysis in userdefined windows, attribute analysis as well as modern interactive displays to provide the full control during the survey.
Fasttrack processingFasttrack and infield processing are typically performed as a part of data quality control routine and for quick evaluation of the seismic image. Often this type of processing runs parallel to the acquisition, i.e. on the seismic vessels. Replication and parallelization allow processors to compute high performance tasks after completion of each block or sail line and provide results to the client promptly.
RealTime Data Quality Control ensures that all acquired data are in the client’s specification. RadExPro has a unique system of reading data files, as soon, as they come to the server and feeding them into the QC flows, resulting in immediate display on each QC plot, without any delay. The set of QC is fully adjustable and can be constructed, based to the specifics of the particular survey and client’s requests. End of line reports with the QC maps are also available. Typical set of quality control products includes:
Source quality control – nearfiled hydrophones check, bubble peak amplitude, primarytobubble ratio.
Data quality control – shot gathers, neartrace gathers, amplitude analysis, spectral analysis, channel maps, brute stack, etc.
