| GeoDepth Seismic Tomography is a state-of-the-art velocity model updating system designed to handle all velocity scenarios, including extremely difficult scenarios (anisotropy, topology, size) and models. Geologically-constrained, it is an optimal tool for large models with complex geology, as well as rich, wide and multi-azimuth seismic surveys used in modern offshore and onshore exploration projects. |
| GeoDepth Tomography combines advanced 3D graphics with a powerful interpretation functionality for automatic picking in both post-stack and pre-stack domains. Due to its specially designed infrastructure and unique, iterative approach, GeoDepth Tomography is able to perform high-performance computing (HPC) using the Paradigm Parallel Framework (PPF), in order to solve tomography equations for anisotropic model parameters and for large-scale models. |
-
GeoDepth Tomography reduces interpretation uncertainty through a comprehensive set of input data, including wide- and multi-azimuth data, well information, and a priori geological knowledge, and by using geologically constrained solutions.
-
A fully automatic process enhances efficiency and saves time by minimizing user involvement.
-
New tools for automatic picking of reflection surfaces and residual moveouts on gathers enhance ease of use, efficiency and productivity.
-
GeoDepth Tomography improves the strength of subsurface parameter estimation, including anisotropy.
|
-
A powerful combination of high-performance cluster computing, rich bottom-up specular ray tracing in all azimuths and angles, automatic reflection patch picking and residual moveout picking, and anisotropic model parameter updating. These are all applied to the client’s most critical seismic assets, where project turnaround and quality are paramount.
-
Storage of all information, including picks and associated attributes, such as dip, azimuth and continuity (DAC) of reflecting surfaces, surface ID, residual velocity, and others in the Pencil Database. The information can be extracted using either volume-based (ImageDAC) or reflector-based (ImagePICK) operations.
-
Automatic picking of RMO at pre-defined pencil points along the pre-stack data.
-
Multiple inversions to solve the tomography matrix, with different geological constraints applied independently to each geological layer or model creation of complex geology.
-
Optimal operation on large computing clusters with many nodes, enabling computations involving hundreds of gigabytes for typical grid intervals of several hundred meters.
-
Distributed computations over the two main tasks of tomographic matrix creation and solution.
-
Integration of well information (check shots) into tomography equations for solving and controlling anisotropic inverted parameters.
-
Rich set of built-in QC tools
