Supervision and Quality Control

The main function of the software complex "Seismic field control" is to control the quality and quick processing of seismic data during the field seismic operations 2D, 3D. The purpose of the software is to give the user a complete set of tools to solve tasks that are integrated into a single system.

Applying the vast experience of our specialists in the field of processing seismic data, the package includes the features that are required during analysis and data processing. It makes it easier to use the product.

Basic principles:

  • Simple and user-friendly
  • Efficient for large volumes of data
  • The possibility of pre-processing in the field, to facilitate the first stages of the office analysis
  • Wide range of tools to solve tasks
  • Flexible system of organization of internal logic to integrate new features without drastic intervention
  • System requirements, permitting to use not really powerful laptops
  • Interactive response system in Russian.

Implementation area

  • Service quality control for seismic survey operations
  • Processing seismic data in field seismic parties
  • Office processing of seismic data
  • Schedule service of seismic surveys

The software "Seismic field control" allows solving the following tasks:

Evaluation of seismic data quality due to calculated seismic attributes of the seismic record.

The analysis process is greatly accelerated, since the stages of data entry and geometry assignment are not required
More accurate allocation of areas containing mostly signal or interference
This allows mapping a certain type of seismic record with surface conditions
The process of computation accelerates, using all the resources of modern processors
Relieves the user from having to use external applications to process the received data

Preliminary processing of seismic data

A PC “Seismic field control” includes more than 40 modules for processing seismic data, enabling the processing steps from input data to obtain a migrated hexahedron directly in the field.
