Tigress data loading applications let exploration and
production (E&P) personnel transfer data to and from the
Tigress Project Data Store (PDS) for use in the
Tigress applications.
Data is loaded from a variety of third party databases and file
and tape formats using graphical interfaces and specially developed
links. Links to other databases, applications and file formats can
be written using the Tigress PDS Developer's Toolkit, transforming
the Tigress PDS into an open integration platform and data
distribution hub.
On this page you can find summaries and features lists for:
Seismic import and export
Summary
Import and export 2D and 3D seismic and navigation data in a
variety of different formats.
Features
You can:
- import and export 2D and 3D SEG-Y data in a variety of formats
(SEGY, Charisma and Landmark SEGY in 8, 16 and 32bit)
- specify 3D surveys using a single inline/crossline origin point
and rotation, or three corner points
- load 3D data in inline or crossline order
- read 2D navigation data from SEGY trace headers (new in version
4.6.3), or from UKOOA ASCII files on tape or disc
- extract elevation, static correction and water depth data from
the trace header and store in the database for later display in the
Seismic Interpretation application
- import cultural data from ASCII files
- generate time slices.
There is a dump facility for EBCDIC, binary SEG-Y files, binary
trace headers and data values to be decoded and viewed.
Post-processing options include polarity reversal, filtering and
scaling.
