Seismic Scanning and Vectorising

Seismic Services - Scanning and Vectorising

Lynx seismic services include the scanning and vectorising of seismic hard-copy sections and basemaps. We will convert paper seismic sections and basemaps into industry-standard exchange formats SEG-Y and UKOOA/SEG-P1.

Once in digital format, your seismic data can be conveniently loaded to interpretation workstations for detailed review, interpretation and analysis.

Using our LEASSV and LEAMAP software we can provide the following service:

Scanning of hard-copy seismic sections (paper, film or microfiche) - black & white, greyscale or colour - with our full-scale A0-sized (40") scanners.
Image editing - removal of seismic interpretation prior to vectorising.
Vectorisation - a number of trace-tracking algorithms can be selected, depending on the character and display type of the original seismic traces.
Post-stack processing - bandpass and time-variant filters, deconvolution, dip filters.
Post-stack migration - Kirchhoff or Finite Difference.
Curve capture - digitise elevations or field statics from seismic scans.
Velocity tables - capture the stacking velocities from the seismic scans.
Location data - georeference or digitise seismic shotpoint maps, output to UKOOA/SEG-P1
Re-projection of seismic location data to your preferred coordinate system.
Reconciliation - insert the XY coordinates into the seismic trace headers.
Static shift - match the datums between different surveys.
Output to SEG-Y, or preload the seismic data into an SMT Kingdom project. Paper QC plots available on request.
Delivery - by FTP, DVD/CD-ROM or tape.

Modern processing techniques can dramatically improve the quality and signal-to-noise ratio of seismic lines originally shot and processed in the 1960s and 70s. After vectorising, we can apply additional post-stack processing to enhance the seismic data, or to improve its fit with your existing digital seismic data in the same area.
