Structural interpretation

Reliable information about structural framework and reservoir properties is a prerequisite for well planning and reserves evaluation. The many years of experience of PetroTrace employees in various oil and gas provinces enables effective integration, analysis and interpretation of all available G&G information in the region under study. High-tech methods of volume imaging, horizon and fault tracing, attribute analysis and inversion increase the speed and accuracy of structural and dynamic interpretation.

Careful collection and analysis of the available amount of geological and geophysical information allows our specialists to create a reliable geological basis for the project. The PetroTrace team saturates seismic interpretation with geological meaning understandable to all those who further use our results on all stages from reserves evaluation to field development. Interactive software tools for analysis and interpretation of well log data, validation of well picks and display of cross sections increase the productivity of geological works.


The most important stage of interpretation is the connection of seismic and borehole data, as well as the tracking of reflective horizons and the identification of tectonic faults. To optimize structural interpretation, PetroTrace specialists calculate all necessary seismic attributes and use volume visualization to quickly understand the geological structure of the field. Efficient manual and automatic tools for correlation and editing of horizons and faults in 3D significantly speed up the process of structural interpretation.


The accuracy of structural models largely depends on the method of converting data from time to depth domain and determines the efficiency of subsequent drilling. PetroTrace interpreters use all available information about velocities in the area and select the optimal time-depth conversion technique depending on the quantity, quality and regularity of the raw data. Close cooperation between processing and interpretation teams allows us to leverage seismic processing velocities to improve the accuracy of depth conversions.
