Over the past year, many different improvements have been added into Prime for the user operating convenience.
1. New toolkit for working with wells.
Inclined wells can now be specified not only through the layers intersection coordinates,
but also in other formats. The possibility of importing las-files has been added. Logging curves can be overlaid on the depth-velocity models and on the seismic sections. Set of
tools for working with wells include Well Tie, stratigraphic ties, signal waveform extraction, velocities correction and etc.
2. Tools added to Builder3d include:
Visualization of CDP super-gathers
with the possibility of interactive mixing by X/Y.
Interactive tool for viewing and
picking of vertical spectra of stacking velocities and residual kinematics.
3. Significantly expanded functionality of the SeisView application:
Added the ability to view SEG-Y files.
Prime data can be can be viewed unsorted or sorted by two or three keys. For each key you can set boundary values and a step. Traces are drawn sequentially or with reference to a key value (if a step is set for a key).
Synchronization of SeisView application with Builder3d. By mouse click on the map in Builder3d you can visualize the seismogram nearest to the clicked location in SeisView.
The list of procedures applied on the fly has been extended (BandpassFilter, Q correction, Filter from library, Header statics, Statics, Surface consistent, Divergency correction, AGC). All these procedures can be stored in a Preprocessing script that can be
applied on the fly within the 3D migration. This eliminates the need to prepare an intermediate data set for the migration.
It is possible to overlay 2D/3D time/depth models, Velocity libraries, Muting, Processing, Adjusting on seismic data.
The header field can be visualized as
graph not only in a separate window, but also overlay it on seismic data.
A window control panel has been added.
The ability to group windows to synchronize changes in visualization settings between windows has been added.
A tool for estimation of the background absorption parameter Q has been added.
4. Added the ability to apply on-the-fly Preprocessing script configured in advance to the Migration 3D Cluster plugin in SeisView. This eliminates the need to prepare an intermediate data set for migration.
We pay equal attention to the development of new processing technologies.
1. The Migration 3D Cluster plugin has been updated with the ability to interpolate seismic gathers during the migration process.
2. New modules have been added. The most important ones are:
AbsorptionEstimation - estimation of time-variable and laterally variable parameter
of absorption Q.
MIA (Model-Based Image Attribute Correlation) -- calculation of depth seismic gathers with realized nominal dip/reflection angles of the ray migration pattern at each depth point for each distance.
It is performed based on the correlation of the results of the attribute migration response -
conventional depth seismic gathers and depth seismic gathers obtained with a specialized weighting function, that "labels" the
value of the geometric attribute of the ray pattern in the unknown tangent region of the summarizing migration operator and migrated data.
ReadSEGDPlus - read dataset files in SEGD rev 3.0 format.
3. A new plugin AVAZ_Image_Synthetic has been added.
It is intended for calculation of the ideal seismic response model and for solving the problem of obtaining seismic response from a medium whose characteristics (velocity, density, anisotropy parameters) are described either by a formation model or by cubes of elastic parameters. The main task of this plug-in is to obtain an idea of the seismic cube character and AVO character from CIG gathers that correspond to the used CIG and the elastic parameters used (related to the model or to the longitudinal/transverse wave velocity cubes and density cubes used). This tool can be used during the model building phase, on which seismic modeling will be performed in the future and the capabilities of the processing tools will be investigated.
In addition, code optimizations were made to accelerate the work of some applications.
For example, the procedure of metacube data reading in sorts different from real metacube sorting has been accelerated.
