PREDICTING SENSITIVITY TO POSITIONING FOR SEISMIC SURVEYS |
| 摘要 |
A geophysical target-oriented approach is proposed to derive seismic sensitivity to 4D positioning mismatches, which focuses on the impact on the reflective response from the reservoir. The sensitivity indicators provide information about the seismic impact, in terms of reservoir imaging, of a surface positioning mismatch. Some embodiments capitalize on the use of legacy data, enabling a fast-track analysis to be carried out on the velocity model to extract trends and mapping of lateral geological variability. |

1. A method for generating at least one sensitivity indicator associated with an impact on a seismic survey of a positioning mismatch in an area, the method comprising:
assessing a lateral variability associated with the area; and generating the at least one sensitivity indicator based on the lateral variability. |
