RESULTS
The
indicators of hydrocarbon leakage observed show a wide range of seismic
responses. What could be loosely classified as HRDZs constitute the most common
type of indicator seen. All of the HRDZs exhibit, to a greater or lesser degree,
one or more of the three main identifying characteristics, namely amplitude
anomaly, time pull-up and degraded stack response. In some cases, it is clear
that the HRDZs are also closely associated with gas chimneys, producing a
complex, hybrid appearance on seismic data. Seismic amplitude anomalies, simple
gas chimneys, shallow trapped gas and interpreted sea floor carbonate mounds and
pockmarks have also been detected.
