The Indonesian Petroleum Association (IPA) will be conducted the very popular course of “3-D Seismic Interpretation Techniques” in Yogyakarta in year 2010, which will be taught by Dr. Alistair Brown, a world-renowned instructor and AAPG distinguished lecturer.

The instructor is also the author of the AAPG book “Interpretation of Three-Dimensional Seismic Data”. A copy of the latest edition (sixth edition, 2004) of this book will be provided to delegates as part of the course.

This course is designed to train the delegate in those techniques best suited to interpretation of 3D data. Whether the data sets you use are field scale appraisal and development work or more regional scale, large volume reconnaissance interpretation, this course will help you optimize your interpretation.

The following topics will be covered in detail:

1. Introduction:
vertical seismic resolution, the two resolution limits, the seismic wavelet, importance of amplitude and phase control, dynamic range, horizontal seismic resolution, Fresnel zone, seismic migration, regularity and acquisition footprint.

2. Structural interpretation:
slicing the cube, time (or depth) slices and their importance, fault handling, contouring exercise, structural case histories, interpretable structural detail, composite and volumetric displays, phase sections, subtle faults and their detection, coherence, autotracking and its precision, time-derived horizon attributes, tracking validation, generalized procedure, interpretation confidence.

3. Stratigraphic interpretation:
recognition of characteristic shapes, importance of strike view, channels, bars, dunes and carbonate features, resolution limitations, horizon slices and their methods of construction, reconstitution of depositional surfaces, stratigraphic patterns to verify structure, unconformities, turbidite mapping exercise.

4. Color and phase:
limitations of conventional display, color principles, contrasting and gradational color schemes, visibility of amplitude detail, recommended scales, recognition of zerophaseness, definition of European and American polarity.

5. Reservoir identification:
bright spots, dim spots, phase changes, flat spots and their necessary characteristics, impact of color, amplitude and display scales, use of top and base reflections and spatial relationships.

6. Reservoir identification continued:
tuning phenomena in reservoir reflections, importance of zero-phaseness and knowledge of polarity, approach to validation, reservoir limits, occurrence of fluid effects, reservoir identification exercise.

7. Attributes:
classification, amplitude-derived and frequency-derived horizon attributes, windowed attributes, hybrid attributes, 3-D AVO.

8. Reservoir evaluation:
properties affecting amplitude, interpretation regimes, well calibration, composite amplitude, mapping of porosity, net-to-gross and net pay thickness, tuning estimation and removal, pore volume, case histories.
