Fast and accurate regional interpretation enabled by a mixture of multi-resolution support for all data types and volume roaming

Paradigm™ SeisEarth® provides interpreters with a fully functional 3D canvas to view and interpret seismic and well data. This canvas places 2D and 3D seismic and well data in their true spatial relationship which allows the data to be visualized, integrated and interpreted as if the interpreter were viewing the earth volume itself. The 3D view is augmented with traditional section and map views that dynamically share any interpretation. When data is shown in 3D, pitfalls resulting from projections of data from deviated and horizontal wells onto sections or vertical plots in measured or true vertical depth can be avoided. Well data from horizontal wells can be correlated with other well data, seismic data and interpreted horizons without artificial projections that destroy spatial relationships.

Increased Interpretation Precision and Speed

SeisEarth benefits from modern workstations that support large central memories and 3D graphics. Large volumes of 2D and 3D seismic, well and interpretation data can be loaded into central RAM (random-access memory) and shared by the applications. This enables true volume-based interpretation of multiple 2D and 3D seismic surveys and volume-based interpretation of well data. Once volumes of seismic data are in RAM, Paradigm products such as 3D Propagator, FaultTrak and 2D Propagator become interactive tools in the hands of interpreters. This style of interaction enables the interpreters to be deeply involved in the horizon and fault interpretation process while avoiding the fatigue of purely manual picking.

SeisEarth has tools to assist in the computation of fault and horizon intersections and provides direct access to surface modeling. In this way picking and modeling processes can be used together to improve the interpretation. These automated tools allow interpreters to quickly re-interpret large volumes of data and the tools can generate measures of quality that can be calibrated to measure or predict the positional uncertainty of the picks. The end result should be better and more accurate interpretations much sooner and, more importantly, with far less button clicking and fatigue for the interpreters.

Streamlined Processes for Interpreting Large and Complex Surveys

Seismic surveys that are too large to load into RAM may be roamed. Such surveys may contain more data samples to be displayed than even today’s large screens can manage. To avoid aliased displays of 3D seismic displays and maps, SeisEarth supports multi-resolution volumes of seismic data where each volume has been anti-aliased and resampled so that it can be displayed on the screens without alias artifacts. Maps may be generated with target-oriented gridding so that large areas can be displayed on screens with less resolution and without alias artifacts. 2D seismic displays are anti-aliased on-the-fly. Very large volumes of multiple seismic attributes are supported by volume roaming technology which brings into RAM the parts of the volume relevant to the display. The mixture of multi-resolution support for all data types and volume roaming is unique. SeisEarth provides similar tools to accommodate very large 2D seismic data sets.

The ability to use productivity tools such as the 3D Propagator together with ergonomic manual picking of multi-z valued horizons and local tessellation enables detailed picking of complex salt surfaces while minimizing manual effort. Similarly the ability to use automatic fault extraction with automated fault surface building and FaultTrak computer assisted manual fault picking facilitates interpretation of surveys with complex faulting with minimal manual effort.

SeisEarth supports multi 2D and 3D survey propagation for fast accurate regional interpretation and ensure interpretation is tied between different surveys

Support Large-Scale Projects

SeisEarth utilizes relevant oil company asset data, enabling regional scale interpretation to support large projects. With SeisEarth you can:

• Facilitate cross-survey interpretation activities by pre-conditioning multiple surveys with automated mistie analysis
• View and interpret horizontal and deviated wells in 3D, along with seismic and interpretation data
• Represent true spatial relationships between well and seismic data
• Roam through large datasets with anti-aliased displays

Improve Interpretation Quality and Insight

Gain new interpretation insights with SeisEarth 2D and 3D seismic data visualization in true 3D. SeisEarth enables you to:

• Measure horizon pick quality to estimate uncertainty and reduce risks
• Reduce error with mistie and data corrections for multiple 2D and 3D seismic surveys
• Use modeling within the interpretation workflow
• Capture undistorted perspectives of 3D structures during the interpretation process for more insight into the geometries
• Compare fault surfaces produced by the FaultTrak module with those picked manually and calibrate measurements with well data to help measure interpretation accuracy
• Directly enhance SeisEarth interpretation with voxel-interpretation (Paradigm VoxelGeo® ) and seismic facies classification (Paradigm Stratimagic™) using seismic data in shared memory
• Enhance seismic interpretation with well log correlation and cross sections (Paradigm StratEarth™)

Produce Faster, More Efficient Results

Reduce repetitive actions and interpreter workload with the SeisEarth ergonomic design and robust productivity tools. You can:

• Complete interpretations sooner by capitalizing on multiple CPU cores, 3D graphics and large memories of modern workstations
• Perform horizon, fault, fault outline and marker picking using SeisEarth productivity tools and multiple 3D seismic and well views to aid correlation
• Enhance productivity with hot keys, mouse functions and multiple “undo” and “redo” functionality
• Make multi-z-value horizon interpretation tasks easily ergonomic
• Enjoy faster updates and displays of section, map and 3D views, since data is shared through memory rather than disk files
• Make model adjustments without leaving the project using seismic imaging, reservoir characterization and pore pressure prediction workflow integration
