PetroTrace has many years of experience in processing and interpreting seismic data, which allows it to create its own developments that accelerate the work and improve the quality of seismic images. Today the company has its own software development department with high-class programmers, who in tandem with geophysicists and geologists create domestic solutions.



The iNSTA-Geo© software package is a domestic development and serves as an effective tool for constructing a top section model of the environment. The software package is based on the approach of interactive correction of static corrections based on the analysis of sections obtained on the spatially fixed summation bases (SFP© - Surface Fixed Patterns). This technique can be used for all types of data. In comparison with traditional approaches, such as building the upper section model with first-breaks tomography, the interactive correction of static corrections does not depend on the quality of first-breaks data. In addition, the iNSTA-Geo software package has a wide range of procedures for processing seismic data, including first-breaks modeling of the upper section, velocity analysis, refining the long-period trend from horizontal spectra, working with maps and data, and functionality for simultaneous work with 2D and 3D data.

Batch processing of seismic data

Batch processing of seismic data

Main program window. Within the iNSTA-GEO software system, the functionality of generating complete seismic data processing tasks is implemented.

The iNSTA-GEO software package provides full functionality for creating and running seismic processing jobs. Saving and editing jobs makes it possible not only to save different versions of processing tests, but also to run a whole array of jobs using a queuing system. More than 40 modules provide the flexibility to work with the program. The development team is also working on new modules in iNSTA-GEO to achieve quality results within a single software product.

Interactive static corrections

Interactive static corrections

Example of an interface for working with patterns for partial summation.

The iNSTA-Geo software package implements an interactive approach to static corrections. The concept consists in the formation of static corrections as a time-shift model adequately reflecting the heterogeneities of upper part of the section, including the following steps:

  • separation of heterogeneities zones along the profile (area)
  • determination of the wave travel time increments on the heterogeneities boundaries and the preliminary estimation of the static anomaly
  • an additional automatic correction of the different components of the static corrections

An important component of the methodology is how to extract the information about heterogeneities from the processed seismic data. To identify zones of heterogeneities and to estimate the level of time delays within them, we use

  • various trace summation schemes (obtaining full and partial - in different ranges of distances, including with fixed position of summation bases - CDP, CSP,CRP summations)
  • separate gathers (with kinematic corrections), on which the in-phase axes are detected sufficiently confidently
  • travel time curves of the first breaks or acquisition of traces of equal offsets for the initial part of the record
  • horizontal velocity spectra V^CDP both on the full spread and on its half
  • summation results (CDP, CSP,CRP) with introduction of different variants of time delays as static corrections.

Upper part of the section model construction on first breaks

Upper part of the section model construction on first breaks

Creating a refractor model in Time Offset Scatter.

The use of first breaks information is the basis for building a model of the upper part of the section. The iNSTA-GEO software package implements the ability to trace first breaks and build a layered model to calculate static corrections. The program implements a convenient functionality that allows setting the initial model of the medium in a few minutes using semi-automatic tools. The resulting velocity models can be smoothed and transformed from depth to time domain. Using a combination of the upper section part  model building tools and interactive static corrections in iNSTA-GEO software, it is possible to take into account the influence of a variety of near-surface heterogeneities.

The software complexes of PetroTrace have been tested and used in real projects for the last 5 years. During this time, the images of the environment obtained during re-processing of the same data became more resolved and reliable. The software development department at PetroTrace has been improving the modules based on feedback from geophysicists to keep the programs up to date. PetroTrace's software packages are an excellent extension of your seismic data processing toolkit.
