Geologic Time Model
This method uses a comprehensive approach which consists of a three-step computer aided workflow. Our algorithm first tracks first every possible horizon within the seismic volume and assigns relative geological ages automatically. Then the interpreter edits the relationships between horizons and updates the model in real time to obtain the optimum solution. Based on the horizon grid, a geological time volume is computed from the seismic.

Spectral Blueing
Spectral Blueing method helps the interpretation of seismic areas with too low amplitude values. It is a quick technique which can be easily applied on seismic data and improves the vertical resolution of seismic volumes. Following the same workflow as Coloured Inversion, this method is based on reflectivity time series computed from acoustic impedance well logs. It defines an operator used to increase the vertical resolution of seismic data.

Coloured Inversion
Inversion of seismic data to acoustic impedance often requires time and expertise. Despite the benefit of such a process, inverted data are only used in a limited number of cases. To overcome this, Coloured Inversion is a quick technique which can be easily applied on seismic data and performs a simple understandable inversion process.
Well Correlation
Build interactively a geological correlation panel across well log data, at any location along the trajectory by slicing horizons and creating 3D geological layers. Well tops and horizon interpretation are checked and vertical differences automatically quantified in an interactive table. Fine well to well correlation can be done with the horizon stack, in both depth and time domains. Flattening options on markers or horizons are also available.

Various methods to manage and/or convert data from time to depth domain are proposed in this module such as interactive seismic-well tie with a comprehensive method, intuitive logs depth adjustment and real time seismic depth stretching. This process is involved in many applications for reservoir characterization and velocity modeling.

Seismic-Well Tie
The seismic-well tie tool is simple and interactive, including all the required processes for sonic calibration, wavelet extraction and synthetic seismogram generation. Time shift, stretch and squeeze can be applied in real time with useful editing options to perform a quick and precise calibration. Moreover, synthetic seismic volumes can be computed in real time thanks to the geological time model and multi-well constraints.

Depth Conversion
Seismic image can be stretched in real time from time to depth domain by assigning velocity models. Interpretation can be done in both domains interactively because the display of all objects are transformed within the viewer. This tool proposes various domains of application to check velocity cubes, seismic-well tie and also save horizons and volumes in the depth domain.

Velocity Modeling
Build interactively a velocity model by defining intervals from the RGT model and convert the seismic in depth instantaneously. Various methods to compute velocity values are proposed: constant, linear or from the wells. The depth conversion in real time allows adjusting the velocity model accordingly. The interpretation can be done in both domains interactively since the display of all objects is transformed within the viewer.
