Geoscan - Seismic Section Scanning
Trace reconstruction has been carried out for a number of years. This is due in the most part to the workstation revolution causing interpreters to need their data in digital format and because the data available to many international explorers is only in analogue form. Theoretical geophysicists used to 80 dB of dynamic range on modern data can be disdainful about data which has been recorded and processed under dubious conditions, then displayed with a limited dynamic range and finally reconstructed, modified and redisplayed. The fact is that useful results can and regularly are being provided to the industry through the application of Spectrum’s technology.
Geoscan was written to transform seismic data plotted as analogue traces into digital values in SEGY format. Under circumstances where the original display is near perfect quality the software will provide a near perfect reconstruction of variable area/wiggle data.
Spectrum has developed a number of specialist tools and considerable expertise in coping with seismic data which is displayed in less than perfect and even extremely poor condition. Many clients have been delighted by Spectrum's ability to turn poor originals into useable form for further processing and interpretation.
Once digitised the full suite of processing algorithms for post-scan processing are available:
- Migration
- Post stack multiple attenuation
- Noise attenuation
- Phase matching of data sets
- Filtering and scaling
