Challenge: Before drilling a sidetrack for an
under-producing well, clearly image a subsalt structure obscured on surface
seismic images
Solution: Perform 3D vertical seismic profile
(VSP) with a dual setting of the VSI versatile seismic imager to obtain
high-quality redundant data. Use Q-BorSeis borehole seismic processing and the
Petrel E&P software platform for seismic processing and data
integration
Results: Clearly and efficiently imaged the
subsalt structure, revealing additional faults responsible for low production
to optimize sidetrack planning
