Direct hydrocarbon indications from fluid contacts - stop calling them 'flatspots'! ...
So called 'flatspots' rarely have the appearance of flatness, even at proven gas and oil fields and on seismic data that has been converted to depth using best-practice methods. The appearance of fluid contacts on seismic reflection data is influenced by several controls, most notably, flu...

So called 'flatspots' rarely have the appearance of flatness, even at proven gas and oil fields and on seismic data that has been converted to depth using best-practice methods. The appearance of fluid contacts on seismic reflection data is influenced by several controls, most notably, fluid type; burial depth; saturation; and the size of the 'flatspot' anomaly compared to the imaging velocity resolution. Many cases of non-flatness are caused by lateral velocity variation in the overburden. Often the structural form of the trap itself is the cause. Non-flat seismic hydrocarbon contacts are seen at shallow gas hazards in Sakhalin, Russia; at oil fields in the Santos Basin, Brazil; and at 'gas on oil' accumulations in the Browse Basin, Australia. So, it appears that non-flat 'flatspots' are ubiquitous, suggesting an urgent name change is needed for this form of DHI.
