Evaluation of in situ reservoir mechanical behaviour requires relevant input data. In addition to the fundamentals of geomechanics (theories of elasticity and failure mechanics, borehole stresses, and acoustic wave propagation), a major part of this course will thus include the important task of obtaining parameters that are relevant for geomechanics field application, be it from laboratory tests or from analyses of field data.

Learning outcome

General competencies
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.

Skills
Analyze stresses, pore pressure and strains around boreholes and in the reservoir using available field tests, well-logs, drilling events and laboratory data.

Knowledge
Understand how the stresses are changed as a result of petroleum production and how these changes influence the recovery and 4D-seismic, as well as mechanical stability during drilling and production. Understand elastic limits and failure mechanics. Understand basics of poroelasticity, thermoelasticity, viscoelasticity, plasticity and anisotropy. Understand better how effective stresses affect well-logs and seismic data.

Required prerequisite knowledge

Basic knowledge of mathematics and physics is required.

Exam

Weight Duration Marks Aid
Continous assessment1/1 A - F
Continuous assessment: ~3 theoretical tests and 1-2 projects (mandatory presentation and/or graded report). All are equally weighted.
Both parts must be passed (by obtaining a minimum average of 40% on each) to pass the course.
If students fail or want to improve their grade, they must take the entire course again the next year.
