Common Focus Point technology - An example from the Red Sea area of Saudi Arabia

Based on the principles of Common Focus Point (CFP) technology we develop a velocity-depth model estimation methodology. This approach is applied in t he CFP domain which is halfway between the two focusing steps: focusing in emission and focusing in detection. The principle of equal traveltime is th e criterion of the macromodel validation and update. By picking the time di fferences between the synthesis operator times and the one-way times in the CFP gathers a velocity and depth update can be calculated. We illustrate t he effectiveness of this CFP-based velocity-depth estimation with a 2-D dat aset from the Red Sea basin of Saudi Arabia.
