Amplitude increase suggests
pressure drop (flow) along entire
well length
Fig. 8.8
Amplitude increase (green) suggests that pressure drop is occurring everywhere in the
vicinity of the producer well; there had been concern that it was producing only from some
segments of the faulted and channelised reservoir. A 4-D seismic survey was cheaper than
establishing the flow from each section of the well by direct measurement, which would have
interfered with production.
In another field in the same area, repeat surveys established that a well was effectively
draining the whole area around it
