Processing

Our success rests on:

-  25 plus years experience in processing and interpretation of onshore and offshore 2D and 3D seismic data for Russian and international clients: Gazprom, Yukos, Rosneft, Statoil, Amoco, BHP, BGR, Total etc.

-  High performance hardware.

- Processing software from Landmark, Paradigm and Tsunami the world’s leaders in software development.

Statics

An extremely complex overburden in the Northern Russian offshore and West Siberia calls for applying long- and short-period statics.

SMNG has computed 2D and 3D refraction and residual  statics using  ProMax-SeisSpase  software.

Pre Stack Depth Migration

 

 

 

Paleochannels (Caspian Sea)              

Pre-Stack Time Migration

 

 

In the presence of lateral velocity heterogeneity, with or without structural complexity, many of traditional seismic processing assumptions are invalid

Vint-Depth Velocity Model

 

 

 

As a consequence, correct imaging and geologic risk assessment can only be provided by Pre Stack Depth Imaging
