Course content

CO2 storage ¨C Physical and chemical processes focuses on the thermodynamics and reaction kinetics of CO2 storage as well as the thermodynamics of CO2 and relations with other basin fluids: formation water, hydrocarbons, sulfur gases a.o. Equations of state and fluid phase equilibria as well as prediction of fluid properties (density, viscosity, a.o.) is reviewed in relationship to burial history and post-depositional consequences for reservoir and cap rock properties of CO2 storage. Furthermore, the course will cover themes as

• multiphase flow and trapping mechanisms
• fluid-rock interaction caused by CO2, especially geochemical and geomechanical responses
• modeling of geochemical reactions
• case studies modeling of CO2 injection and storage migration
• stress conditions, deformation and fracturing, fault-reactivation.

Learning outcome

To give PhD fellows an understanding of the physical and geochemical constrains of subsurface sedimentary systems affected by injection of CO₂.

Give the theoretical basis for multiphase fluid transport, and geochemical and geomechanical consequences. This is required in order to quantify and simulate the main interactions and short and long-term effects of CO₂ storage. Finally, the objective is to give the PhD students practical skills in fluid-flow and geochemical simulations.

Knowledge aims:

• Be able to identify and define the major processes and reactions taking place during geological CO₂ storage
• Be able to describe and quantify these processes separately and in concert

Level of skills:

After finishing the course, the PhD student should be able to

• calculate fluid phase boundaries of relevance for CO₂ injection and storage
• perform computer simulations of equilibrium and kinetic reactions caused by CO₂ injection
• perform advanced computer simulations of multiphase fluid-flow and estimate relative trapping mechanisms.

Prerequisites

Formal prerequisite knowledge

Basic training in chemistry and physics;  KJM1100 ¨C General chemistry (continued),  FYS1000 ¨C Physics- the foundation of natural sciences and medicine (continued) or similar courses.

Recommended previous knowledge

Physical chemistry/chemical thermodynamics in addition to general knowledge in physics and geosciences.

Overlapping courses

10 credits overlap with GEO5910 ¨C CO2 storage - Physical and chemical processes (continued)

Teaching

Access to teaching

The intensive course is held together with GEO5910 and is over two weeks in the fall semester with regular lectures and computer modeling exercises. A literature case study is to be presented during lectures and an individual modeling project is to be submitted as a report as well as presented during lectures.

Attendance at the first lecture is compulsory. Students who fail to meet, are considered to have withdrawn from the course unless they have previously given notice to the Studies administration, email address: studieinfo@geo.uio.no

Examination

The two individual presentations and report counts 50%, final written or oral exam 50%.

Language of examination

In this course any written exam questions or assignment questions may be available in English only.

Grading scale

Grades are awarded on a pass/fail scale. Read more about the grading system.

Resit an examination

Students who can document a valid reason for absence from the regular examination are offered a postponed examination at the beginning of the next semester.

Re-scheduled examinations are not offered to students who withdraw during, or did not pass the original examination.
