DELPH Seismic Interpretation

REAL-TIME AND OFFLINE GEO-INTERPRETATION


DELPH Seismic Interpretation is the most advanced 2D/3D geo-referenced data processing and interpretation package in the industry. It processes any sub-bottom profiler or seismic data, and offers complete geo-referenced processing and interpretation capabilities in an intuitive software environment. DELPH Seismic can be used as a post-processing tool as well as a real-time QC tool during data acquisition.

Dedicated speed corrected profile display allows on-screen distance, thickness and slope measurement on sub-bottom data. DELPH Seismic Interpretation provides all necessary outputs from printing to reporting and mapping (reflectors, isopach maps, iso-contours). It is the perfect tool for sub-bottom data analysis and further reporting.

Highly optimized, with all functions being available for single profile analysis or batch data processing, mapping and reporting, DELPH Seismic saves a lot of time to geophysics who spend it in data analysis rather than software manipulations.
In real-time and post-processing, DELPH provides a powerful geographic visualization software - DELPH RoadMap - that overlays seismic track lines, interpretation and reflector surfaces with other data like side-scan sonar, bathymetry, magnetic maps, aerial photography or coastline vectors.

True depth vertical corrections


Vertical resolution in seismic data is of no use without proper vertical corrections. A vertically coherent dataset will enable cross-line checks, interpretation and modeling of the reflectors. Vertical corrections bring sub-bottom data to true-depth allowing better integration with bathymetry models. DELPH Seismic makes use of all available data to vertically rectify sub-bottom data.
  • Geometry corrections (mounting lever-arms, angular offsets)
  • Swell correction from bottom tracking
  • Heave correction from motion sensor data
  • Topographic correction / True-depth rectification from pressure sensor data for towed / AUV / ROV data
  • Tide compensation from tidal correction files or direct input
  • Vertical static correction, with automatic leveling between crossing lines
  • Snap to bathymetry function to fit sub-bottom data to an existing bathymetry model
  • 3D Display of sensor's navigation in the map offers an efficient QC of the equipment flying conditions
 
Interpretation capabilities


DELPH Seismic has been a pioneer in providing a global survey interpretation approach, removing all constraints from the traditional scrolling displays. A full profile approach makes the interpretation more intuitive. Rich interpretation tools combined with full reporting capabilities drastically improve the geophysicist's workflow and save time.
  • Databasing of all reflectors in the survey project
  • Manual and automatic seabed tracking
  • Manual and automatic reflector tracking
  • Design reflectors with one or more legs, split & join reflectors
  • Profile flipping to allow parallel interpretation of profiles that were recorded in alternate ways
  • Excluded areas can be designed to select unwanted data (turns, etc.) and discard it from further processing and reporting
  • Ground Truthing design and import overlays core logs onto the sub-bottom profiles and in the 3D map
  • 2D drawing and annotation tools to overlay pictures, comments, contours on top of the data
  • 2D and 3D feature interpretation from within the 3D the map like faults, etc.
  • Printer and PDF output of interpreted profiles
  • Batch export of horizons and thicknesses
 
Geo-Interpretation capabilities


Interpreting small to complex seismic datasets never was so easy: Featured DELPH RoadMap application offers 3D cartographic visualization of all survey data. From raw to processed and interpreted data, it displays seismic profiles, interpreted and modeled reflectors in connection with the profile interpretation environment. The whole vertically corrected and geo-referenced sub-bottom data displays and provides a better QC and understanding of the surveyed area. Intuitive data browsing from the map or tie-crossing marks saves time in managing projects.
  • geoSections: Vertical display of geo-referenced seismic profiles - 3D fence diagrams - with transparent water-column (optional)
  • DTMs: Surface modeling of interpreted reflectors from picked horizons with 2D / 3D visualization
  • Isopach Maps: Thickness map generation from data interpretation
  • Iso-contour generation from all maps
  • 2D and 3D map interpretation (points, polylines, polygons, 3D models, core logs)
  • Cropping of all maps to survey area or from designed polygons
  • Tie crossings display, browsing and vertical leveling
  • Synchronized 2D and 3D display of the picked reflectors
  • Synchronized 3D geo-referenced cursor between the map and the interpretation environment
