Seismic vectorizing quality varies widely across the industry. Although some vectorized SEG-Y files may initially appear acceptable, they will often be missing much of the underlying data. 24x7well log digitizing services CO SEG-Y output derives from newly developed vectorizing software with several new techniques.
We use image editing software specifically designed for large images and can consolidate multiple seismic images into one section.
Image markings or hand-drawn interpretation are edited out before capturing the underlying seismic.
Shot-point and CMP data is recorded.
Extra EBCDIC information is typed from the label (if it exists).
Our software predicts the invisible positive overlap of the peaks and also tracks the negative trough wiggle lines.
Each trace is bandpass filtered (outside the original frequency range) and amplitude balanced across the whole trace.
The final output is presented as a 32 Bit IBM Floating Point SEG-Y file.
A comprehensive report spreadsheet is included.
Navigation information can be added to the SEG-Y files for easier loading.
Most colour sections can be accurately digitized to SEG-Y. Common examples of this display type include greyscale, black-red and blue-red.
24x7well log digitizing services CO offers high quality seismic reconstruction to SEG-Y from most image sources: photographs, desktop A4 scanned images, computer screen-captured images, data room images, CGM, JPEG, PNG image files etc., all the way up to high resolution large scale seismic hardcopy or plots. Seismic type displays such as Vertical Seismic Profiles (VSPs), EPC and ocean bottom surveys can also be digitized.
An extensively interpreted seismic image converted to SEGY using our Fill Interpolation Filter.
Our new seismic ‘Fill Interpolation Filter’ at work.
Interpretation normally persists in screenshot image capture, but with Fill Interpolation we are able to remove it from the SEGY.
This is the most common display type for 2D seismic and well synthetics and has the positive ‘peak’ samples of each trace filled in black, and the negative ‘trough’ samples shown as a thin line. 24x7well log digitizing services CO can directly track each seismic trace within this display type and then intelligently interpolate any gaps to complete the full waveform.
This is similar to the above seismic data display, but has no negative thin line shown and only the positive ‘peak’ samples of each trace are filled in black. To maximise quality, 24x7well log digitizing services CO intelligently predicts the positive peak amplitude values and a natural amplitude for each negative trough sample is then calculated.
Most clean-up work is included within the seismic vectorization process. However, in some cases seismic sections may be extensively marked or have significant drawing interpretation over them. If that is the case, extra time may be required to clean these images before digitizing. The final seismic reconstruction is promptly returned inside oil and gas industry standard SEG-Y format files, accompanied with a comprehensive report spreadsheet.
If you have any hard copy seismic sections or seismic images that you would like in SEG-Y format, we will gladly offer you a free test line to help highlight the impressive results that only we can achieve.
