Stratigraphy
Sequence Stratigraphy
A framework of genetically related
stratigraphic facies geometries and
their bounding surfaces used to
determine depositional setting
Sequence Stratigraphy
Subdivision & interpretation of sedimentary
record using a framework surfaces seen in
outcrops, well logs, & 2-D and 3-D seismic.
Include:
Surfaces of erosion & non-deposition (sequence
boundaries)
 Flooding (trangressive surfaces [TS] &/or maximum
flooding surfaces [mfs])

This framework used to predict the extent of
sedimentary facies geometry, lithologic character,
grain size, sorting & reservoir quality
