Seismic Data INTERPRETATION
Seismic Interpretation
Seismic interpretation is the
technique for interpreting stratigraphic and geological structural information
from seismic data. Conventional seismic interpretation
implies picking and tracking laterally consistent seismic reflectors for the
purpose of mapping geologic structures, stratigraphy and reservoir architecture.
The ultimate goal is to detect hydrocarbon accumulations, delineate their
extent, and calculate their volumes. Conventional seismic interpretation is an art
that requires skill and thorough experience in geology and geophysics. The main
approaches for the interpretation of the seismic section are:
·
Structural Analysis
·
Stratigraphic
Analysis
Structural Analysis
It
is the study of reflector geometry on the basis of reflection time. The main
application of the structural analysis of seismic section is in the search for
structural traps containing hydrocarbons. Most structural interpretation uses
two-way reflection times rather depth.
Stratigraphic Analysis
Stratigraphic
analysis involves the subdivision of seismic sections into a sequence of
reflections that are interpreted as a seismic expression of genetically related
sedimentary sequences.
