SEPARATION OF UP-GOING AND DOWN-GOING WAVEFIELDS INCLUDING THE DIRECT ARRIVAL |
| 摘要 |
At least some embodiments are directed to a system. The system includes a processor and a memory coupled to the processor. The memory stores a program that, when executed by the processor, causes the processor to calculate a pressure response of a first sensor, and correct pressure wavefield data obtained from the first sensor responsive to a first acoustic wavefield. The correction is based on the calculated pressure response of the first sensor. The pressure response of the first sensor is responsive to a second acoustic wavefield having a propagation path between a source of the second acoustic wavefield and the first sensor, in which the propagation path includes no reflection from a subsurface formation. |

1. A system comprising:
a processor; a memory coupled to the processor; wherein the memory stores a program that, when executed by the processor, causes the processor to:
calculate a pressure response of a first sensor;correct pressure wavefield data obtained from the first sensor responsive to a first acoustic wavefield, the correction based on the calculated pressure response of the first sensor; wherein:
the calculated pressure response of the first sensor is responsive to a second acoustic wavefield having a propagation path between a source of the second acoustic wavefield and the first sensor; and
wherein the propagation path includes no reflection from a subsurface formation. |
