Prime 5.0 version

It has been almost two years since the release of Prime 4.1. During this entire period, the version has been actively developed and tested, and we are pleased to announce the release of version 5.0.

Users who follow our news on social media are already aware of some of the new features. Below we will briefly list the main ones.

The data storage structure in the project directory has been completely redesigned. This has made it possible to unify and simplify work with all data types, primarily seismic data. At the same time, the backward compatibility has been preserved — older projects will be able to be opened in the new version of Prime (the Figure 1 below).

2. The JobWizard has been enhanced with the ability to construct job chains. For each task, launch parameters are pre-configured (processing objects and computing resources). This eliminates the need to constantly switch between Liman/JobWizard/Builder3d applications to run routine procedures, allows visualizing the seismic data processing sequence on a tablet, and provides the option to obtain the final result with a single button click (the Figure 2 below).

3. In the earlier versions of Prime, tasks from modules were constructed in JobWizard, while plugins could only be launched interactively from Builder3d. Now plugins are similar to modules and can be used in a regular job script in JobWizard.

4. There is no longer any need to worry about the coordinate type for 3D data (whether they are global or local). Previously, all responsibility for coordinate type management rested entirely with the user. They had to monitor them and select the correct conversion options in different places (local to global / global to local). This created confusion and often led to errors. There is no need to think about coordinate type anymore. All the work is conducted exclusively in global coordinates.

5. Q-tomography and Q-migration technologies have been implemented. The Q-migration algorithm is based on attribute migration for estimating the dependence of the Qmig parameter at each point of the image during the migration process. This will allow for correct compensation of absorption effects on post-migration common image point gathers and complete control over this process.

6. The interface of the BI WFT 3D plugin has been significantly simplified. It is used for predicting multiple waves using SRMP/SBRMP in 3D, as well as (if the user has access to the Modeling function) for 3D modeling based on Boundary Integral technology and demigration.

7. New modules and plugins have been added:

1. FirstBreaksPickingPlus is a first arrival picking tool based on a unique proprietary robust algorithm that effectively processes even extremely noisy data (the Figure 3 below).
2. The FirstBreaksTomography2D module and FirstBreaksTomography3D plugin are designed for constructing a layered velocity-depth model of the Upper Part of the Section based on first arrival times.
3. The FirstBreaksModeling plugin is designed for calculating first arrival times in a specified velocity-depth model, as well as for computing QC attributes that assist in editing first arrival picks. The modeling results can be utilized for re-picking based on the obtained solution (the Figure 4 below).
4. The FxyFilter module provides FXY filtering capabilities for both 2D and 3D data with regular and irregular geometry (the Figure 5 below).
5. The IndexVersion plugin creates an indexed version of seismic data, enabling its use in job chains.
6. The MultiChannelEditing module has been redesigned with several significant enhancements. It now features the ability to set time- and frequency-variable Threshold values, as well as time-variable filter base settings. A new filtering method has been introduced, based on F-xy filtering, which not only corrects the amplitude spectrum but also effectively addresses phase spectrum issues (the Figure 6 below).
7. The SlidingSubtraction module has been completely redesigned. The ability to average 3D data with both regular and irregular geometry has been added. The capability to perform frequency band subtraction, subtract multiple models simultaneously while adding their Hilbert transforms as subtraction components, and a robust subtraction option using a norm different from L2 have also been implemented (the Figure 7 below).
8. The QCAttributes module is a new attribute calculation module that replaces DataAttributes and DatasetAttributes (the Figure 8 below).
9. The Shift module has been completely changed. The ability to input time-variable shift and apply shift from header has been added. The capability to tie shift to horizons has also been introduced (in the most general case, such shift can be a function of (t(x, y), l)). This makes paleoreconstruction possible in batch mode with the usage of a task. Previously, it was only available in the interactive MigrationTools application, which worked with the only one line.
10. Into the AbsorptionCorrection module the support for time models with the Q parameter defined by spline functions has been added. Additionally, it now includes an option to obtain Qeff/Qmig parameter traces from the second input stream and a high-frequency option to limit filter strength at upper frequencies (the Figure 9 below).
11. Into the AbsorptionEstimation module the support for determining the Q parameter defined on horizons by spline functions has been added. Additionally, it now includes an option to output Qeff/Qmig parameter traces.
12. The Migration 3D plugin adds a Q migration mode. The time migration has also been enhanced with the capability to account for anisotropy (non-ellipticity) parameter when using a velocity cube.

8. The interactive applications Wavelet, MigrationTools, and Inversion are now considered as outdated and have been moved to the prime-legacy package. SeisView and Modeler are their modern analogues.

This is just a small part of the changes. In addition, extensive work has been done on:

• the program performance improvement (the reading of data in non-native sorting through the use of Data Reader Server technology has been significantly accelerated, 2D model writing into the database also has been accelerated),
• the user interface improvement,
• removing redundant entities (profiles, modules ReadCube/WriteCube).
• adding numerous minor yet highly useful tools to facilitate the processor’s work (spectrum pickers for 3D data, histograms, cross-plots, advanced visualization settings).



Prime is included in the Unified Register of Russian Programs for Electronic Computers and Databases (Register entry No. 2561 dated December 23, 2016).
