3d Seismic |
| We will try to provide helpful tips on 3d seismic methods
and use. |
| 3d is like 2d - just more of it. |
| Most 3d surveys are shot in 2d. |
| The current practice avoids basic principles of seismic
measurement. |
| To get better results from your 3d: |

|
Request to look at unmigrated stacked data. |
|
|
Remove the color variable density. |
|
|
Study the wiggle variable area displays. |
|
|
Review and interpret both stack and migration. |

INFORMATION WE AGREE WITH |
|
| From CGG: |
|
| 1. 3D seismic has proven to be the most
effective method for finding oil and gas by identifying sub-surface
structures likely to contain them. |
|
| 2. Under certain circumstances the presence of
hydrocarbons can be detected directly with seismic. |
|
| 3. Repeating seismic surveys over producing
fields allows oil companies to monitor the movement of hydrocarbons in
the reservoir. |
|
| 4. 4D
seismic is one of the main tools being used by oil companies to
extend the life of oil fields in the North Sea, and is starting to be
used elsewhere. |
