Multi-3D and -2D survey data and interpretation within SeisEarth 3D Canvas enables a better understanding of basin evolution.

The Paradigm SeisEarth seismic, multi-survey system provides geoscientists multi-2D and -3D tools for creating seamless interpretation and analyzing seismic data from prospect scale to basin scale.

Basin Perspective
Visualizing data from multiple surveys in 3D space enables interpreters to gain new insights into the seals, sources, migration paths and reservoirs for hydrocarbons over all or part of a basin. In fact, the ability to assemble well, seismic and interpretation data into a 3D view for a basin-sized area can change the nature of an interpreter’s questions. Instead of asking, for example, “Where are the hydrocarbons in this prospect?” the question can be elevated to “Where are the prospects in this basin?” Or, “Why isn’t there a producing field here?”

Prospect Perspective
A prospect interpretation is far easier when its setting is understood from viewing the basin data. Rather than imagining the processes for a basin based on the prospect details, the interpreter can discover new relationships for seals or lack of seals when the producing wells are viewed in 3D, together with the seismic and interpretation data for the larger area. All of this added insight can lead to new plays or help to avoid nonprospective areas.

SeisEarth enables viewing of 2D and 3D seismic data in true 3D so that structures, faults, stratigraphic features and fluid contacts can be correlated across lines and between surveys, and then understood in the same fashion as for single 3D seismic surveys. Its suite of applications provides productivity tools for computer assisted horizon and fault picking, as well as fault outline generation for both 2D and 3D seismic data to further empower seismic interpreters.

Simultaneous interpretation of multiple 2D and 3D seismic surveys

• Simplify correlation of data between surveys using 3D Canvas displays of seismic lines and traverses through multiple surveys
• Provide detailed displays for event correlation in in the SeisEarth Section window with waveform displays of traverses through multiple surveys
• Ease production of project maps by gridding and display of picks from multiple surveys in Base Map
• Reduce error with multi-2D/3D mis-tie analysis and correction for reflection time, amplitude and phase
• Capture interpretation with data on hardcopy or in movies

Manage huge data sets on a typical work station

• Using either the 3D Canvas or Section module, improve display quality by anti-aliasing 3D and 2D seismic data in space and time when the data samples are larger than the resolution of the display
• Avoid aliased displays of large surfaces in the Basemap module by using target-oriented gridding and contouring
• Allow large volumes to be interpreted on work stations by volume roaming data sets too large to load into RAM

Robust productivity tools for interpreters

• Use the advanced waveform horizon auto-picking in the 2D or 3D Propagator add-on tools for 2D and 3D seismic, respectively, to reduce mouse clicks and improve horizon pick quality
• Reduce mouse clicks with ergonomic manual picking; allow single valued, multi-z valued, and propagated or tracked picks to be easily selected for one horizon
• Improve the accuracy of interpreted fault shape and reduce fatigue using computer-assisted fault picking in the FaultTrak module
• Reduce mouse clicks with automatic fault contact generation and fault outline generation
