PetraSeis®

Seismic Interpretations on your PC

PC-based seismic interpretation and display tools, providing 2D and multi-volume, multi-survey 3D functionality within a single PETRA® project. PetraSeis allows today’s geoscientist greater productivity by providing a PC-based suite of seismic interpretation and display tools with an intuitive user interface and a workflow that supports an iterative, interactive process for quick, quality results. 

PETRA cross section with depth calibrated seismic, raster and digital logs, monthly production data, perforations, shows, IP volumes, and a seismic horizon map.

2D/3D Interpretation • Data management • SEGY data loading • Logs and Synthetics • Trace Processing • Mapping • Geologic Integration • Math Functions

2D/3D Interpretation

• Interactive horizon picking
• Sub-sample interpolation
• User picked seeds
• Auto picking between seed picks
• Auto flattening on horizons
• Multiple arbitrary lines displayed
• Highly accurate fault polygons
• Unassigned and assigned faults
• Interpretation on multiple volumes 

Data Management

• Utilizes the PETRA relational database, and its many functions for importing well, logs, tops, cartographic files, and others from all major data vendors, as well as common, ASCII tabular data.
• Provides a spreadsheet-style interface for importing horizons, velocity functions, etc.
• Exports all data, including interpretation data in a variety of industry standard and user-defined formats.

SEGY Data Loading

• Provides a powerful suite of tools for loading and manipulating SEGY files from SCSI tapes or disk files.
• Also allows writing the SEGY data back to tape from PetraSeis or SEGY disk files.

Mapping 

• PetraSeis has many options for displaying horizon time, amplitude, velocity, depth, and various interval calculation around an interval. The integrated mapping makes it easy to switch between map types.

Seamless integration between PetraSeis and PETRA mapping	3D time slice
Trace Processing Phase rotation, AGC scaling Static shift, filter attributes Multiple inlines, cross lines, arbs Color or variable area Show/Pick from previous picks 2D combined line display Display wells and tops
3D two volumes-color from semblance wiggle traces	Inline and cross-lines in a combo view

• Uses the sonic logs to generate velocity files and synthetic seismograms
• Easily interact with the filter parameters, phase, gain, and polarity to make the generation of the synthetic seismogram effortless.

Geologic Integration Is designed to directly access data from the PETRA database and overlay files, and to provide wiggle trace images and horizon maps to PETRA Actively contributes to integrated cross section displays.  It can create a trace image through PETRA specified wells, flatten the traces on a horizon, convert the image from time to depth and display the image as a backdrop to a cross section
3D visualization incorporates multiple data types for a more detailed analysis
Math Functions Horizons can have many user-defined arithmetic operations applied, generating isochron, isopach, depth maps, etc. Includes many predefined functions, such as absolute value, logical operations, change sign, smooth, flatten, interval average, and semblance.
