PROCESSING AND INTERPRETATION OF GEOPHYSICAL DATA
Turning geophysical data into valuable knowledge for your projects
MODERN methods of analysis of geophysical data
Data processing and complex analysis is carried out by software using modern specialized software. The data processing graphs are based on our own developments in the field of seismic imaging.
Our solutions for marine geophysics:
On-board real-time data quality control
Amplitude preserving processing to analyze the dynamic characteristics of the recording
structure and amplitude interpretation
On-board express processing
Geological hazard identification and mapping to ensure the fail-safety of hydrotechnical buildings and risk assessment
Data quality control
Uploading data to the processing system
Checking data integrity
Assigning the geometry of observations
Control of signal excitation stability
Control over the assignment of observation geometry
Monitoring of the spectral characteristics of the recording
Viewing a record of one channel and building a bottom profile based on data from one channel
Uploading data with the assigned geometry of observations for further processing
Building a preliminary summary time section according to the profile
Building maps and graphs based on various recording attributes
Calculation of record attributes
