Abstract
Summary
Vertical seismic profiling (VSP) data have the potential to provide migration image with improved resolution around borehole than surface seismic data due to its distinctive acquisition geometry. Special accommodations are required in processing and imaging of VSP data. To partially handle the inevitable velocity uncertainty in field data application, we use our previously proposed method, reverse time migration with random space shift, as the imaging engine. Dedicated data preprocessing is applied to the three-component elastic data to get upgoing P wave for imaging. Real data application demonstrates that our workflow could provide better image around the borehole than surface seismic data.
