About the position

Are you motivated to take a step towards a doctorate and open up exciting career opportunities? As a PhD Candidate with us, you will work to achieve your doctorate, and at the same time gain valuable experience that qualifies you for a further career in higher education and research, in and outside academia.

The Department of Geosciences (IGV) has a vacancy for a full-time 100% position as a PhD Candidate.

Your immediate leader will be the Head of Department.

About the project

Technology development in geothermal energy and deep drilling has made great progress in recent years, especially in the US and Canada where pilot projects produce large amounts of energy, both heating and electricity production. The technological advances within cost-effective drilling have their starting point in the fracking industry, and other oil and gas industries.

Mainland Norway consists mostly of igneous and metamorphic rocks. This poses drilling technical challenges that differ from the sedimentary rocks on the shelf. Nevertheless, there is a lot of experience and technology to be gained from the Norwegian petroleum industry. The geothermal gradient is moderate, but a climate with large seasonal variations also provides opportunities to combine heating and cooling, deep drilling and seasonal heat storage (GeoThermos).

Energy security and emergency preparedness have become an increasingly important topic – not least to have systems for heating and industrial processes that are not very dependent on supplied electricity. Locally produced energy will also reduce the need for costly development of the national and regional power grid.

What the doctoral work will focus on will be developed in collaboration with the candidate and national and international industry players. Many aspects can possibly be addressed, e.g.:

Drilling in hard crystalline rock in areas with low geothermal gradient
The overall geothermal system and use must be described. Clarify which concepts may be relevant in Norway.
Describe the research front and actively collaborate with the scientific community in Norway and internationally.
The research topic will be focused on drilling – high-frequency hydraulic hammer, directional drilling and fishbone technology. What does it take to make drilling economically sustainable, i.e. how can the drilling speed be significantly increased?
Explore and solve practical challenges in close collaboration with the leading drilling operators, equipment suppliers and industry associations in the Nordic countries – how to handle faults, swelling clays, rock stresses, drill wear (bit replacement).
Collect and analyze existing and new data on drillability related to mineral content and degree of metamorphosis in crystalline rocks.
Drilling optimization using machine learning, e.g. predicting rate of penetration (ROP) and wear.
Investigate the possibilities in automation and robotization and the use of artificial intelligence.
Electric drilling and other methods for reduced climate footprint.
Combine deep wells with shallow seasonal heat storage (GeoTermos) and possibly short-term storage (accumulation in both water tanks and with phase change material - PCM).
Digital twins of the system for real-time decisions, based on petroleum field experience.
LCA and economic conciderations.
Modeling and reservoir management using (and adapting) petroleum/CO2 storage tools for simulating flow and pressure response, as well as thermal storage. Also analyzing new and existing data and calibrating models.

Duties of the position

Complete the doctoral education until obtaining a doctorate
Carry out research of good quality within the framework described above
Academic publications and popular science dissemination
Participate in the research group Engineering Geology and Rock Mechanics
Participate in international activities such as conferences and/or research stays at foreign educational institutions

Other career-promoting work

Be prepared for changes to your work duties after employment.

Required selection criteria

Decide on what is to be defined as absolute qualification requirements and what is to be defined as desired qualifications (the latter are placed in the module below):

You must have an academically relevant background within engineering geology, rock mechanics and/or geothermal energy.

You must have a strong academic background from your previous studies and have an average grade from your Master's degree study, or equivalent education, which is equal to B or better compared to NTNU's grading scale. If you do not have better grades from previous studies, you must have an equally good academic foundation. If you have a weaker grade background, you may be considered if you can document that you are particularly suitable for a PhD education.
You must meet the requirements for admission to the Faculty of Engineering https://www.ntnu.edu/iv/doctoral-programme.
For communication and co-operation with the Nordic industry players, good oral and written presentation skills in Norwegian or another Scandinavian language equivalent to level B2.
Good oral and written presentation skills in English.
Knowledge about the geological conditions in Norway and the Nordic countries.
Personal suitability, strong collaboration and communication skills will be emphasized.
