Depth Estimation Using a Calibrated Regional Linear Velocity Model - Field Matzen, Vienna Basin

P069 DEPTH ESTIMATION USING A CALIBRATED REGIONAL LINEAR VELOCITY MODEL – FIELD MATZEN VIENNA BASIN K. RESCH 1 E. STRÖBL 2 and K. MILLAHN 1 Summary A regional velocity-depth model of the central area of the Vienna Basin has been developed based on borehole seismic data (26 check shots and VSP surveys) and DMO velocities of a 3D seismic survey (20 by 30 km 2 ). Both velocity functions interval velocity V as well as DMO velocity (VDMO) can be reliably approximated by a linear model V(Z) = V0 + kf * Z down to a maximum basin depth of
