Integrated solution

for interpretative processing

of 2D/3D/4D/3C/4C seismic data

Technologies of XXI century

2017

Vladimir M. Glogovsky (1936-2008) is a doctor of

Physical & Mathematical Sciences, an outstanding

mathematician and geophysicist, author of the

concept of the Prime interpretative seismic data

processing. He developed the applied theory of

reverse kinematic problem solution: building

depth-velocity model of subsurface/media along

with its feasibility and consistency verification.

Vladimir M. Glogovsky implemented the interactive

approach and real-time accounting for a priori

information, which allows making geologically

meaningful decision directly in the course of the

processing.

Sale of licenses and technical support of the Prime software system;

The Prime software concept is based

on the applied theory of building depth-

velocity media model accompanied by

the model validation and consistency

check.

The program provides an opportunity

for continuous interactive accounting for

a priori information, which allows

making geologically reasonable

decisions during the processing.

Thus, the program allows considerable

decreasing the risk of obtaining

incorrect result that contains false

structures in geological column.

Concept

of Prime software system

6

Thick-layer depth velocity model consistent with a priori geological

information is used in the course of processing; this allows taking

into account variations of physical properties in both vertical and

lateral directions.

Core of Prime is building a subsurface depth-velocity model on the basis of unconventional

algorithms that are efficient in complicated and diverse seismic and geological conditions.

Unique opportunities

of the Prime software

The Prime software system includes modules, techniques and tools conventional

for classical processing as well as unique algorithms developed for the recent

years; they are actively applied to solve modern tasks of increasing complexity.

Advantages

of the Prime system

9

Provability and validity of processing results in any stage

Forming the basis depth-velocity model is tested for validity and consistency. For

this purpose, a special criterion of the model sufficiency in terms of a priori

knowledge about the media is calculated. Thus, each processing result

(intermediate or final) is reasonable in terms of geology.

Parallel computing

To handle large data volumes, it is essential that software allows working not only

properly but also quickly. Prime meets these requirements as the user can

customize procedures settings for one test line, save the sequence of procedures

with specified parameters to database, and then apply stream-oriented processing

to the full amount of data. Most of compute-intensive procedures in Prime are

compatible with cluster technologies allowing to use all the computational

resources efficiently.

All the applications use a single common

database. Change of an object in one

application can be immediately seen in

other applications, this reduces time cost

of data downloading/uploading and

reformatting and thus speeds up

processing operations.

Interactive graphic tools make working

with the Prime software system simpler

for users, and simplify the process of

mastering the system.

Interactive applications

in Prime software

10

The software includes several graphical applications responsible for

different tasks, they are: building velocity model, calculation of migrations

and comparison of results, parameters testing, constructing processing

streams, etc.

after wavefield datuming.
