f Lithology Discrimination through Velocity Analysis – A Solution trough Method

In this paper, we have implemented the technique to a study area that was located in deep water and seven geological stratigraphic units were used for velocity analysis. Issue arises when we tried to tie the stratigraphic units to well markers. A thin stratigraphic unit is prominent in the seismic section but not being interpreted in the well as a unit (Figure 2). We expect that this thin layer will create variations in the provelocity analysis within the target location. Due to the variations, checkshot seemed to be inaccurate in<br>further calibrating for time-to-depth conversion below the thin sedimentary layer. A study of solution trough has been applied with the composite displays of the solution troughs indicate that within the top and the second uppermost units, there is clearly inconsistency in stratigraphic unit parameters.
