Model study showed that when SNR is no less than 2, the seismic data is more reliable.

模型研究显示：对于储层研究，信噪比不小于2的地震资料是相对可靠的。

It is therefore necessary to have the seismic data corrected for phase and earth filtering.

为了做到这点，必须对地震记录进行相位校正及大地滤波校正。

The more McMoRan and its team work through the seismic data the more they learn.

FORBES: McMoRan Update From Enercom Oil & Gas Conference

Father-and-son-team Orazio and Salvatore Consoli help gather the seismic data -- three generations of their family have worked on the volcano.
