Objectives and Content
The goals of course is to provide the students with a detailed insight into the physical and thermodynamic nature of hydrate as they appear as and industrial problem, as well as in nature as energy source, environmental problem and potential geohazard
The course contains a detailed description of the nature of hydrates and its properties as well as conditions for stability but also to a large extent anasis of inability to reach stability when coexisting with other phases in a processing or transport environment or in nature. Modern theories for estimation of the kinetics of hydrate nucleation and growth is also discussed along with simpler theories which may be easier for use in reservoir modeling or modeling of hydrate formation risk in industrial situations.
On completion of the course
the student should have the following learning outcomes defined in terms of knowledge, skills and general competence:
- Are able to analyze specific industrial situation with respect to possibility of hydrate formation
- Can evaluate various means of prevention of hydrate problems (plugging)
- Knows how to calculate maximum amount of water that can be permitted in a gas in order to avoid hydrate problems
- Can evaluate whether hydrate that forms can establish equilibrium with surrounding phases or not
- Understand hydrates in nature and how these hydrates can be produced for energy purposes
- Knows how hydrates can dissociate in nature and give rice to fluxes of hydrocarbons to sea and air
- Knows how geomechanical instabilities may be generated by hydrate dissociation
- Can analyze complex multiphase systems in terms of possibility to reach equilibrium or not
- Can describe the thermodynamics related hydrate formation, dissociation and non-equilibrium.
- Can analyze specific process plants with respect to critical points for possible hydrate problems.
- Can participate in project related to hydrates in nature as is able to evaluate thermodynamica aspects of specific reservoirs
The students understand how hydrates form, dissociate and rearrange in interactions with other solid and fluid phases in industrial settings as well as for hydrates in nature

Credit Reduction due to Course Overlap
Access to the Course
Access to the course requires admission to a master programme/doctoral education at the Faculty of Mathematics and Natural Scienceswww.uib.no/matnat/52646/opptak-ved-mn-fakultetet
Teaching Methods and Extent of Organized Teaching
The teaching method is by:
Lectures/ 4 hours per week
Tutorials/ 2 hours per week
Project/ 20 hours
Compulsory Assignments and Attendance
A minimum of 2/3 of the tutorials have to approven in order to get access to exam. The project has to be among the approven.
Lectures and tutorials define pensum so each individual student is responsible for keeping up to date on what is lectured during lecture hours and tutorial hours
Forms of Assessment
The forms of assessment are:
Written examination (4 hours)
Due to the measures taken to avoid the spread of Covid-19, UiB is closed for on-campus assessment. As a consequence, the following changes is made to assessment autumn semester 2020:
- Oral examination instead of written examination
Examination Support Material
Basic calculator allowed in accordance with the regulations specified by the Faculty.
Approved calculator models include: Casio fx-82ES PLUS and Casio fx-82EX
The grading scale used is A to F. Grade A is the highest passing grade in the grading scale, grade F is a fail.
Spring semester and autumn semester.
The reading list will be available within June 1st for the autumn semester and January 1st for the spring semester.
The course will be evaluated by the students in accordance with the quality control system at UiB and the department.
The Programme Committee is responsible for the content, structure and quality of the programme and courses.
Contact information for the course coordinator is available at «Mitt UiB», alternatively contact the student advisor.
The Faculty of Mathematics and Natural Sciences and Department of Physics and Technology are administratively responsible for the course.
