CHARACTERIZATION TECHNIQUES Date & Venue The Advance Seismic Reservoir
Characterization Techniques Course
will be held at Holiday Inn Hotel - About the Course In this Course the participants learn to apply various seismic
attributes to solve the stratigraphic problems in
field exploration and development. Proper uses of seismic attribute can extract
information from seismic data that is otherwise hidden and will enhance the
capability of predicting, characterizing and monitoring hydrocarbon reservoirs.
The seismic inversion and complex attributes are used for geometry delineation
and reservoir properties description, whereas the AVO and 4-D seismic
techniques are used for gas/fluid detection and recovery monitoring. The
techniques can assist also in better definition of reservoir continuity and
flow unit, their physical characteristics and distribution, and to aid the well
delineation. Detail Course agenda is given in the opposite page. The Course
comprises of approximately 40% theory and 60% workshops, in which 90% of the
problem-set packages are
Who Should Attend Geophysicist, geologist, petroleum/reservoir engineers
or managers who desire a strong background on seismic interpretation. Course Language Course will be given in English and Bahasa
Indonesia (bilingual). DAILY COURSE AGENDA Day-1 ( Fundamentals of seismic stratigraphy
