Movie 4 showing a depth slice through the reservoir from the 1993 baseline impedance volume

This movie shows a depth slice through the reservoir from the 1993 baseline impedance volume. A small cube of 1999 data is moved across the depth slice in order to interrogate time lapse changes in more detail. The areas around producing well bores show the greatest changes - generally indicative of the evolution of gas from solution produced by a drop in pressure below bubble point.
