IS SEISMIC SEQUENCE STRATIGRAPHY?
Sequence Stratigraphic analysis is a methodology that permits
a geologist and geophysicists to subdivide a stratigraphic section
into a series of time related 3rd Order Depositional Sequences.
- This is
accomplished by the integration of High Resolution
Biostratigraphic analysis, marker species, abundance and diversity
histograms, paleobathymetry and paleoenvironment correlated with
well log signatures and 2D/3D seismic profiles.
are made in time and are not lithologic correlations.
- Maps are
made based on Sequences, Sequence Boundaries or
Maximum Flooding Surfaces

type of reservoir sands in different Systems Tracts in
different paleowater depth.
SEQUENCE STRATIGRAPHY WILL HELP YOU IN:
the 3rd Order Depositional Sequences and Systems Tracts that are
associated with the potential hydrocarbon reservoirs, source rocks
the play concepts for the reservoir section, coastal belt sands,
shingled turbidites sands, sheet sands, and channel overbank sands
(parallel to strike): incised valley fill sands and slope fan
channel sands, (perpendicular to strike) and basin floor fan sands
that form pancake shaped reservoirs.
the geometry, continuity and distribution of the reservoir sands
both vertically and laterally.
