METHOD AND SYSTEM FOR SIMULTANEOUS ACQUISITION OF PRESSURE AND PRESSURE DERIVATIVE DATA WITH GHOST DIVERSITY |
| 摘要 |
A marine streamer spread for acquiring seismic data, the spread including a streamer having a first portion and a second portion; the first portion including both first pressure sensors and pressure derivative sensors for acquiring the seismic data; and the second portion including second pressure sensors. The first portion imparts ghost diversity to the seismic data by having a variable-depth profile and the pressure derivative sensors impart polarity diversity to the seismic data. |
