Can we model seismic patterns by DNA
From Aminzadeh (2004)

Depth Imaging & ModelingNext-generation earth modeling will incorporate quantitative representations of geological processes and stratigraphic / structural variability. Uncertainty will be quantified and built into the models The shared earth model will become the centerpiece for end-to-end technology integration from seismic imaging through reservoir and well performance simulation. As cycle time and costs for reservoir modeling and prediction fall, integration and feedback with real-time operational data become practical.
“So far as the law of mathematics refer to reality they are not certain; and so far as they are certain, they don’t refer to reality” Albert Einstein, 1951

Seismic Imaging
Seismic imaging technology will continue to improve interpretation reliability in complex imaging environments, suchas sub-salt and overthrust playsInteractive 3D depth imaging and velocity modeling will become a standard procedure.Imaging while drilling will help fine tune subsurface images through new image updating techniques. Multi-component and time lapse measurements will grow in use for the reservoir management business, driving down unit costs, expanding application, and stimulating advances in imaging and interpretation technologies.

IT TRENDS
Seismic processing and interpretation technology will continue to ride the exponential growth curve in computational capability and connectivity. Virtually all work will be done via the Web, with interactive, on-demand access to applications, compute engines, and data. The Web will become the key enabler, reducing costs, providing worldwide access to technology, and supporting adaptation to local exploration and reservoir management requirements. More sophisticated human-machine-data interfaces will be developed beyond the capabilities of today’s visualization centers. Advanced measurement systems will create a new flood of data about reservoirs, wells, and operating facilities
