About The Seminar.
Reflected waves amplitude can significantly change with lithologic
variations through which the waves propagate and with increasing offset
between the seismic source and the receiver. Hence, the correlation between
amplitude change and offset can be utilized to infer the physical
characteristics of corresponding rocks. This celebrated Amplitude Versus
Offset (AVO) techniques has been used as direct hydrocarbon indicator (DHI)
for the last three decades, and proves to be a valuable exploration tool.
Moreover, this offset-dependent amplitudes (or strictly speaking,
reflectivity) has also been proven as a good approximation in the study of
deeper crustal features. Theoretically, the technique has been used to
bridge / relate rock characteristics in seismic (global / macro) scale and
those in local (micro) scale.
Meanwhile, the quest to understand complex reservoir model, such as
cracked or fractured reservoir, has recently amplified; especially when
there is a lack of conventional seismic amplitude analysis to capture
fracture / crack scale dependent anomaly. Critical things ought to be
thoroughly observed in the fractured reservoir analysis include: pore-fluid
pressure variations and azimuthal seismic amplitude change. By which, the
relation between the two is still subject for further study. In practical
aspects, when doing the analysis one should focus on surface seismic data
processing to ensure the feasibility and reliability of the crack /
fracture.
Observing the above considerations, the objectives of this workshop are:
1. To discuss the integrated aspect of fractured reservoir from Geology,
Geophysical, and Engineering point of view.
2. To discuss necessary steps in seismic data processing / imaging for
advanced seismic identification technique on cracked / fractured reservoir.
3. To describe and integrate fracture set models to infer reservoir
physical characteristics embedded in the seismic wave.
4. To explore the integration of seismic - rock physical interpretation
on fractured reservoir with pore / fluid pressure; in this case, the
determination should use surface seismic data.
Who Should Attend
Geophysicist, geologist, petroleum/reservoir engineers from oil industries
or universities or managers who need a strong knowledge on seismic analysis
and modeling for fractured reservoir using seismic inversion and AVO
techniques.
