ABSTRACT
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. |
