Abstract:
A comparative study of graphical methods and velocity analysis of 2-D seismic reflection data has been carried out and presented in this paper. The anomalies on which these studies were tested were taken from the Niger Delta. The depths to the Benin, Agbada, and Akata formations were estimated employing both graphical methods as well as velocity analysis of 2-D seismic reflection data. The results indicate that the two separate methods applied yielded approximately the same value for the depths to the top of the subsurface. This work has further reconfirmed the importance of some graphical methods in interpretation of data such as the one used in this work. It is interesting to note that the applied graphical method estimated the depths to the bottom of these structures which could not be estimated using only 2-D seismic reflection data.
