ABSTRACT
We integrate 3-D seismic,
wireline log, and production data to demonstrate that seismic amplitude
maps of two pools in a Pleistocene lowstand delta complex of the offshore
Gulf of Mexico image reservoir compartmentalization by depositional features
and faults. The GA interval of the Eugene Island Block 330 Field is composed
of stacked deltaic lobes, each of which consists of complex associations
of distributary channels, clinoforms, and base-of-slope failure complexes.
Production is from "updip" facies (including delta front and mouth bar
sands) at the top of the interval. The highest amplitudes associated with
the seismic horizon that marks the flooding surface at the top of the reservoir
are associated with high-porosity (and high-permeability) clean, charged
sands that depositional processes have not distributed uniformly. One of
the two pools has a gas cap, and so the high amplitude response is expected
(classic "bright spot"). The other pool has no gas cap, but the charged
sands are also associated with high amplitudes because the in situ gas-oil-ratio
of the oil is high (400 to 500 scf/bbl). In this second pool, there is
a good qualitative relationship between production character and the combination
of seismic amplitudes and structural position, with the best, most consistent
production from high-amplitude areas on the crest of an anticline. |
