Features:
TOMO+™, a 2D nonlinear
tomographic imaging and statics interpretation program from GeoTomo LLC,
brings seismic imaging capability to a new level. TOMO+™
includes a state-of-the-art wavefront tracing technique for calculating
traveltimes and raypaths simultaneously. The approach is rapid and
unconditionally stable for any velocity contrast. TOMO+™
combines conventional and recent inversion theories to solve an inverse
problem valid for a continuum in both model and data space, and obtain a
stable and high-resolution solution. TOMO+™ also provides
capabilities for geometry, traveltime, and refractor analysis. More
importantly, TOMO+™ allows users to perform iterative
traveltime picking and tomographic inversion or refractor analysis to
improve picked times and velocity solution alternatively. TOMO+™
is designed using a Java architecture that runs on both Windows and
Unix.
TOMO+™ version
1.6 provides:
- Manual and automatic picking techniques for
2D/3D SEGY data, conversion from SEG2 to SEGY, capability for improving
time picks with tomographic predicted times (2D/3D), survey geometry
display, SEGY header analysis and editing, extraction of time picks from
SEGY header, convertions from GMG, GLI3D, ProMax picks to TOMO+ format,
and various SEGY display modes.
- Traveltime display, velocity analysis,
automatic picking of delay times, instant analytical velocity model
construction from crosshole or refraction data, calculation of
reciprocity errors, decimation of shots and receivers, automatic removal
of poor picks, selection of partial data.
- Building 2D velocity models or reflectors
with arbitrary interfaces or objects using a mouse button, conversion of
velocity model to grids for raytracing, migration, and tomography,
display of 2D grid velocity models with raypaths and adjustable color
range.
- Designing optimal 2D survey geometries for
high-resolution imaging, create survey geometry with a geometry builder,
2D raytracing for land and marine, first-arrival or reflected
traveltimes and raypaths for any survey geometry, including converted
waves, 2D refraction, crosshole, and VSP traveltime tomography, 2D
refraction traveltime migration, complete capabilities for creating
migration data and QC control.
- Refraction, crosshole, and VSP raypath
display, 2D refraction statics-time calculation from tomography
solutions or delay-time solutions, and graphical display.
- Nonlinear tomography techniques allow users
to image the Earth and obtain high-resolution solutions without any
simplified structural assumption. Rapid and reliable solutions save cost
and reduce exploration risk.
- Interactive modular tool set provides
step-by-step approach to refraction statics solutions, making TOMO+™
ideal for production environments.
- This one-stop solution package solves
tomographic imaging problems with any survey geometry, refraction,
reflection, cross-hole, VSP, or a combination of them. TOMO+™
is applicable in both oil and gas exploration industry and environmental
and engineering industry. It has been also proven to be an
effective tool for educational use.
