| 摘要 |
The present invention, in certain embodiments, discloses methods of acquiring seismic data and increasing the areal density of CMP coverage or increasing the areal coverage of CMP lines or both by towing a plurality of streamers (400-430) with one or more vessels (403-409) wherein the streamers comprise a plurality of seismic sensors for receiving and recording data. The methods include towing at least one seismic source (470, 480) on a first source vessel (402) wherein one or more sources contribute to data acquisition for a first set of CMP survey lines. The methods include towing at least one seismic source (450, 460) on at least one other source vessel (409, 406) wherein at least one source of said at least one other source vessel contributes to CMP survey lines separate from said first set of CMP survey lines. |
