Seismic Section Scanning & Conversion

OvationData offers a full range of seismic section scanning, seismic trace reconstruction and seismic vectorization services to the oil and gas industry. Our specialized seismic scanning and conversion service enables you to convert your valuable and often irreplaceable hard copy legacy seismic sections to digital SEGY format data. This restoration not only ensures long term data preservation, but facilitates the application of advanced post stack seismic processing and the interpretation of the resulting digital data within a modern workstation environment.

Why convert your hard copy seismic sections to digital data?

  • Why convert your hard copy seismic sections to digital data?
  • Apply post stack processes such as filtering, migration, deconvolution and noise attenuation
  • Integration and overlay of historical data with new surveys
  • Allows the data to be re-displayed at different scale
  • Ensures preservation of expensive and often irreplaceable legacy data
  • Provides recovery of the “missing pieces” where digital data has been lost or damaged
  • Ensures long term, digital data management and archiving responsibilities are met

Scanning:

Using state-of-the-art scanning equipment, OvationData can scan your paper seismic sections from sepia, film or paper and produce a raster image file. Using advanced seismic trace digitizing software, we then carefully track and reconstruct the data. This includes tracking of peaks and troughs, restoration of clipped peaks, and interpolation of trough values if none are displayed, for total waveform reconstruction

Processing:

Conventional post-stack processing routines are then applied to enhance the data. Basic processing may include filtering, mute, AGC, trace mixing and trace interpolation. For older vintage seismic data, the application of post stack processes such as FK or FX noise reduction filtering and scaling and predictive de-convolution generally result in significant enhancement of the original data.

Shot point positions can be inserted into the headers of the digitized seismic data, either from supplied files or by digitizing from a shot point map. Accurate positioning information is critical to the use of the vectorized data.

On completion of scanning, conversion and data enhancement, we then output the digital data to your specified format and deliver it back to you either electronically via the web or on the output media of your choice.
