This course examines the processes leading to the
formation and accumulation of carbonate & Siliciclastic rocks and how
sequence stratigraphy provides a predictive method to understand the formation
of these reservoirs and application in oil and gas industry.
The principles and the practical application of sequence
stratigraphy are studied, together with discussion on how this improves our
understanding of subsurface reservoirs. Diagenetic changes that carbonate rocks
undergo are also analyzed, and, where possible, set within a sequence
stratigraphic framework.
Finally, integrating all subsurface data to de-risk
hydrocarbon exploration and development from sequence Stratigraphy point of
view.
Learning Objectives
Upon the
successful completion of the course, participants will:
ü Understand what are the different types of
carbonate hydrocarbon reservoir and the different palaeo-environments in which
they are deposited
ü Integrate sedimentary core, sidewall core and
log data for carbonate facies
ü Be able to recognize and interpret the
petrography of the main carbonate reservoir types
ü Be able to identify the main sequences on
seismic
ü Be able to integrate other geological data and
then identify sequences and parasequences on well logs
ü Be conversant with the terms and definitions
used in carbonate sequence and seismic stratigraphy
ü Be able to use sequence and seismic stratigraphy
towards new play definition and as an aid in play and prospect risking
ü Understand the processes that control
carbonate deposition
ü Understand what controls porosity and
therefore reservoir development in carbonate rocks
ü Be able to understand the complex controls on
the deposition of carbonate rocks and both primary and secondary depositional
environments
Training Methodology
The course will not only presented by showing and
interpreting the material in detail, but also the participants will work
together using a real data to apply all the workflow and to project their
previous knowledge and experience onto the course, they also encouraged to
bring their own data so that real working examples can be reviewed and
interpreted.

professionals but will greatly benefit:
- Petrophysicists
- Geo-Modelers
- Geologists
(Exploration and Development)
- Sedimentologists
- Seismic
Interpreters
