Most deep-water development projects are planned using high-quality 3-D seismic data and sparse well control. Economic considerations require large reservoir volumes to be drained with relatively few wells. We have used 3-D seismic data to constrain large-scale, deterministic reservoir bodies in a 3-D architecture model of Pliocene turbidite sands of the “E,” or “Pink,” reservoir, Prospect Mars, Mississippi Canyon Areas 763 and 807, Gulf of Mexico. A geological interpretation derived from 3-D seismic data and three wells was linked to 3-D architecture models through seismic inversion, resulting in a reservoir rock property distribution incorporating all available data. High-resolution reprocessing of a high-quality marine seismic dataset resulted in the ability to deterministically map sedimentary reservoir bodies. Distinguishing subtle stratigraphic shingles from faults was accomplished by detailed, loop-level mapping and was important to characterize the different types of reservoir compartments. Seismic inversion was used to detune the seismic amplitude, adjust the sand-body thickness, and update the rock properties. This modeling project illustrates how high-quality seismic data and architecture models can be combined in a pre-development phase of a prospect, in order to optimize well placement.

Applications of 3-D Seismic Data to Exploration and Production
Thirty profusely illustrated case studies from around the world demonstrate the latest practical applications of 3-dimensional seismic data. This book covers fluvial-deltaic, eolian, deep-water clastic, carbonate, and structural reservoirs. Special emphasis is placed on the application of 3-D data to development drilling, reservoir characterization, and reservoir management. This atlas is designed to confirm 3-D seismic interpretation in drilling and production--for despite its great impact on the geosciences community, relatively few published case histories have documented 3-D's importance. This book fills that gap.
