Method for extending the lateral subsurface coverage in vertical seismic profiling surveys. |
| 摘要 |
<p>In a VSP survey, the subsurface coverage of the bounce points of primary reflections is limited to one-half the offset between a borehole and an acoustic-source point. To overcome this, the subsurface coverage is extended by use of selected multiply-reflected wavefield arrivals.</p> |
