The main objective of this course is to provide
a comprehensive understanding
of reservoir gemechanics which become
nowadays very important. This course is focused on fundamentals of geomechanics and
rock physics required for key practical applications: pore pressure and
formation stress prediction, determination of optimally-stable wellbore
trajectories, production-induced faulting and subsidence, effects of fluid
injection or/and depletion on fault reactivation and reservoir compaction,
hydraulic fracturing stimulation and sand production prediction.
How will this Training Course be
presented?
The course will not only be 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.
Target Audience
This course is designed for all Oil Industry
Technical Professionals, which will cover from fundamental theoretical background
to high-level real work
information, techniques and workshop.
