Seismic interpretation software
One environment from seismic to models, volumes & reserves.
g-Space unifies seismic interpretation, well-data analysis and 3D geological modeling in a single platform — structural, geological, geophysical, petrophysical and reservoir workflows, in both time and depth.
g-Space is Geomage's comprehensive interpretation and visualization platform for integrated subsurface analysis. It combines seismic interpretation, borehole data analysis, and 3D geological and reservoir modeling in one consistent environment — so geoscientists work across structural, geological, geophysical, petrophysical and reservoir disciplines without leaving the software. A common platform with shared data handling, synchronized 2D/3D visualization, and simultaneous interpretation in time and depth spans the full workflow: data loading, well-tie, horizon and fault interpretation, velocity modeling, petrophysics, mapping, 3D static modeling, and volumetrics for Oil, Gas and CO₂. Developed and supported entirely in-house.
g-Space is a high-performance seismic interpretation and subsurface modeling platform designed for 2D and 3D seismic data analysis, structural interpretation, and reservoir evaluation. Developed for oil and gas exploration, geothermal energy, carbon capture and storage CCS, and critical mineral exploration, g-Space integrates seismic interpretation, velocity modeling, geological modeling, AVO analysis, and reservoir characterization within a unified professional environment. By eliminating data silos and connecting seismic volumes with well and geological data, the platform accelerates confident decision-making from early exploration to drilling and field development.
The software supports pre-stack and post-stack seismic data processing, advanced seismic attribute analysis, time-to-depth conversion, structural and stratigraphic modeling, and volumetric estimation. With optimized computing performance, AI-assisted interpretation workflows, and advanced 2D and 3D visualization tools, g-Space improves subsurface understanding while reducing project turnaround time across energy, storage, and mineral resource projects.
License the packages your project needs.
g-Space is licensed as discipline packages — its modular architecture lets you configure exactly what each project requires. Every package is purpose-built for its specialist, and all run on the common platform (included with every configuration) for shared data, visualization and QC.
Structural Interpretation
Interpret, evaluate and QC seismic-based structural frameworks in both time and depth — import 2D/3D post-stack seismic, autotrack horizons and faults, tie wells, build velocity models and convert to depth.
- Horizon picking with 2D/3D autotracking and amplitude magnetizing
- Fault tracing, fault-network visualization and AI-assisted fault detection
- Seismic well-tie with wavelet extraction and synthetic seismograms
- Velocity model building and depth conversion with uncertainty QC
- Automatic 2D/3D seismic mis-tie analysis and correction
Geological Interpretation
Analyze, correlate and interpret well data to build a consistent stratigraphic framework, then turn markers and interpreted data into maps and geobodies.
- Well log correlation across wells with 1D/2D/3D display in configurable tracks
- Interactive marker picking, stratigraphic correlation and flattening
- Sequence stratigraphy on the international color chart
- Statistical tools: cross-plots, histograms, stereonets, variograms
- Map generation with multiple gridding algorithms and a map calculator
Seismic Interpretation
Advanced seismic analysis, pre-stack evaluation and attribute-based interpretation for quantitative studies — with embedded conditioning tools and high-performance computation.
- Spectral decomposition and structural / stratigraphic / AI-assisted attributes
- On-the-fly attribute calculation and extraction along horizons or volumes
- Pre-stack 2D/3D gather import with advanced 3D gather views
- Polynomial AVO: intercept, gradient, fluid factor, EI/EEI
- AVO cross-plots for lithology & fluid, with polygon-to-map selection
Petrophysical Interpretation
QC, process, interpret and integrate well-log data with geological and reservoir models, from guided import through property propagation.
- Flexible import (LAS, ASCII, DLIS, CSV) with batch LAS wizard
- Log QC: merging, normalization, depth shifting, smoothing, resampling
- Advanced log calculator and ML-assisted log prediction
- Shale volume, porosity, water saturation (Archie, Simandoux), permeability
- Pore pressure & stress, lithology, and property upscaling into models
Reservoir Modeling & Volumetrics
Build 3D geological and reservoir models, populate properties deterministically or stochastically, and run deterministic and probabilistic volumetrics and reserves.
- 3D structural frameworks from horizons & faults (incl. AI-predicted faults)
- Structured S-grids and TetraGrids for complex faulted geometry, in time or depth
- Watertight 3D geobodies with automatic gap detection and repair
- Deterministic & probabilistic volumetrics with sensitivity analysis
- Reserves for Oil, Gas & CO₂; export to ECLIPSE / GRDECL and GOCAD
Multi-User Collaboration
Concurrent, controlled collaboration across multi-disciplinary teams on shared projects, with centralized data, security and a complete audit trail.
- PostgreSQL-based central project database with concurrent access
- Real-time synchronization of interpretation objects
- Role-based access control and monitored user activity
- Automatic versioning with revision & audit history
- Stand-alone project files plus cloud-ready deployment
One foundation under every package
A unified foundation shared by all modules — so data, views and quality control stay consistent across the entire interpretation process.
