AI Technical Summary
Technical Problem
Seismic data clipping due to hardware or software limitations in recording devices leads to inaccurate signal amplitudes, resulting in artefacts and image distortion in subsurface imaging, which existing methods fail to accurately correct using the same type of seismic data.
Method used
A method that reconstructs clipped seismic data using un-clipped seismic data from a different type of recording device, such as hydrophones or geophones, to generate a corrected seismic dataset for accurate subsurface imaging.
Benefits of technology
The method effectively corrects clipped seismic data, minimizing image distortion and artefacts, thereby producing a more accurate subsurface image.
