As oil and gas reserves are depleted, identifying new prospects can be difficult. Potential 3D traps might go undetected with only a single view of the volume. Faults can curve and be hard to interpret on one orthogonal slice. Oil-water and gas-oil contacts and salt diapirs, which do not conform with interpreted time horizons, often require sub-volumes of data before they can be identified and interpreted accurately.

Increase Exploration and Development Certainty

Geoscientists need the ability to interactively sculpt a 3D volume or flatten on specific horizons and apply variable opacity to reveal the full dimensionality of subsurface structures, rather than depend upon assembled individual slices of the volume. This capability dramatically improves interpretation time and success in identifying potential exploration prospects and drilling targets.

Paradigm™ VoxelGeo® is the well-known voxel volume visualization and interpretation software application for 3D seismic data. With the new Paradigm Epos® 4.0 platform, VoxelGeo enables geoscientists to interpret multiple, co-located 3D volumes of seismic data faster, with more precision and less effort. These variable opacity seismic volume displays promote better recognition of even the most subtle potential prospects.

Extend Detection and Interpretation Capabilities

Paradigm VoxelGeo offers interactive, user-friendly sculpting workflows, flattening and opacity rendering, enabling:

• Explorationists to scan and sculpt stratigraphic and/or hydrocarbon-bearing features, and then interpret horizons and faults throughout the volume
• Seismic processors to compare processing in multiple views and interpret salt diapirs for velocity modeling as geobodies
• Development interpreters to produce detailed structural interpretations and use rock property volumes for quantitative interpretation of reservoir intervals

Improve Volume Interpretation Insight

Designed specifically for volume interpretation with multiple 3D views, VoxelGeo helps geoscientists:

• Detect and interpret even the most subtle 3D features in 3D views, versus assembling 3D interpretations from 2D slices, for better insight sooner
• Examine or compare multiple volumes from different viewpoints simultaneously
• Expose 3D features by sculpting the volume, flattening on depositional surfaces and using variable opacity displays
• Produce correct, opacity-filtered volume displays with translucent interpretation
• Identify the locations in a 3D volume with indications of porosity and the presence of hydrocarbons

Achieve Interpretation Precision, Analysis Accuracy

Turn more data into information of value and reduce uncertainty in all aspects of the exploration process:

• Increase interpretation certainty with intuitive displays and rendering accuracy
• Uncover subtle structural geometries with flexible intuitive tools that enable full 3D volume views
• Reveal the detailed structure of the subsurface by isolating and examining a specific irregular sub-volume
• Integrate seamlessly with Paradigm SeisEarth™, Stratimagic™ and Probe™/Vanguard™ to investigate multiple volumes and pre-stack data in detail

Increase Speed, Expend Less Effort

VoxelGeo enables interpreters to interact quickly and efficiently with large volumes of data to:

• Produce rapid results
• Reduce typical interpretation steps, increase productivity, and vastly improve interpretation throughput speed
• Easily generate quality presentations, reproducing image processing techniques applied to generate a composite voxel-image or animate the seismic data
• Make sophisticated fly-through movies with captured data
• Reduce drilling costs, risks and effort by performing collaborative geophysical and geologic data interpretation and drilling with Paradigm DirectorGeo™
