Henry W. Posamentier
ABSTRACT
3D
seismic
data
can play a vital role in hydrocarbon exploration and development,
especially with regard to mitigating risk associated with presence of reservoir,
source,
and seal facies. Such
data
can afford direct imaging of depositional elements,
which can
then be analyzed by applying
seismic
stratigraphic and
seismic
geomorphologic
principles
to yield predictions of lithologic distribution, insights to compartmentalization,
and
identification of stratigraphic trapping possibilities. Benefits can be direct,
whereby
depositional elements at exploration depths can be identified and interpreted,
or they
can be indirect, whereby shallow-buried depositional systems can be clearly
imaged and
provide analogs to deeper exploration or development targets.
The key to successful application of this approach lies in the integration
of sectionview
(stratigraphic) with plan-view (geomorphologic) images. Iterative analyses
of such
images are critical to success. In order to maximize the recognition of depositional
systems,
the user must be familiar with as wide a variety of meaningful geologic patterns
both in section and in plan view. Examples of imaged depositional elements
from both
shallow- and deeply-buried sections are presented. Deepwater deposits, in particular,
have benefited greatly from analyses of 3D
seismic
data
. The understanding
of the
stratigraphic and geomorphologic evolution of these deposits has increased
by orders of
magnitude since the advent of 3D
seismic
-based analyses. In high-cost deepwater
exploration
settings, insights derived from such analyses are critical to reduce risk with
regard
to reservoir presence and reservoir compartmentalization to ensure economic
success.
Depositional elements in settings such as shoreface, shelf, estuarine, and
fluvial, as
well as in carbonate environments also benefit greatly from 3D
seismic
analyses.
