WHAT IS SEISMIC SEQUENCE STRATIGRAPHY?
  • Seismic 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.
  • Correlations are made in time and are not lithologic correlations.
  • Maps are made based on Sequences, Sequence Boundaries or
    Maximum Flooding Surfaces

APPLICATIONS OF SEISMIC SEQUENCE STRATIGRAPHY
  • Establish a series of seismic sequence stratigraphic reference wells that can be loop-tied on 2D/3D seismic for regional basinal analysis
  • Reservoir correlations in an oil and gas field within a sequence.
  • Prediction of ages and surfaces ahead of the drill bit.
  • Predict type of reservoir sands in different Systems Tracts in
    different paleowater depth.
SEISMIC SEQUENCE STRATIGRAPHY WILL HELP YOU IN:
  • Identify the 3rd Order Depositional Sequences and Systems Tracts that are associated with the potential hydrocarbon reservoirs, source rocks and seals.
  • Determine 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.
  • Predict the geometry, continuity and distribution of the reservoir sands both vertically and laterally.
