The Faculty of Technology, Natural Sciences and Maritime Sciences have a vacancy for a position as PhD Research Fellow in Process, Energy and Automation Engineering

About the position

The Faculty of Technology, Natural Sciences and Maritime Sciences has a vacancy for a position as PhD Research Fellow in “Optimal control architecture applied to oil/gas production”. The position is at the Department of Electrical Engineering, Information Technology and Cybernetics, and reports to the Head of Department. The place of employment is Porsgrunn, Norway.

The appointment is for a period of three years. The position does not include teaching duties.

About the PhD-project

The PhD-project is a part of a larger project, “DigiWell”, which is funded by the Norwegian Research Council (project “308817 - Digital wells for optimal production and drainage”), Equinor ASA and University of South-Eastern Norway (“USN”). In addition, highly rated universities and companies are partners in the project.

Petroleum will dominate the global energy mix for years to come, and cost-effective and safe production from existing and near-future oil fields is central in a transition towards sustainable energy economies. Automatic production optimization implies finding a production policy for an oil/gas field with improved profit, and reduced energy consumption. Finding the optimal policy requires perfect system knowledge in the form of a dynamic model of the oil field and production equipment, future energy demand and oil/gas price, over the entire production lifetime of the reservoir.

For real oil/gas fields, this knowledge is uncertain, and properties change with time. The aim of the project is to develop a free modelling toolbox for combined long-term and short-term simulation. Almost all of the results in the project will have direct application in general process and energy industry. As part of the PhD study, it is recommended to spend some time at one of the partner universities.

PhD-project description

The PhD-project considers design of control architecture for new production fields. The concept of control architecture deals with choosing the best sensors/sensor locations and actuators/actuator locations for a system, and is based on a dynamic model of the system: essentially, if sensors and actuators are chosen such that the system has unstable zero dynamics, this may severely limit the bandwidth of robust estimators/observers and feedback controllers, and make it impossible to achieve good control. Examples of unstable zero dynamics include time delays and inverse response. In practice, cost of sensors and actuators will limit how many sensors/actuators are used, and the type that is used.

Some challenges in the project will be (i) to develop a measure of controller performance based on the control architecture, (ii) to develop a measure of sensor/actuator cost, (iii) to carry out a mixed integer multi-objective optimization for choosing equipment and location,(iv) to include model uncertainty in the decision, (v) to make algorithms general and efficient for large scale systems. The integer part is due to an integer number of sensors/actuators and their location, and the multiobjective part is due to balancing attainable performance based on control architecture against equipment cost.

Dynamic system models used in the control architecture study will be provided by other groups in the “DigiWell” project; models may be concentrated and linear or nonlinear, or distributed. Normal operation will be close to some equilibrium, and design based on linear models should be given first priority. The developed methods will be generic, and can be used for any system, also all types of land-based industry. Choice of control architecture is particularly important for systems where there is a high cost of modifying the architecture once production has started, such as for oil/gas production.

In summary, the developed methodology should be general, and should be implemented in a suitable language, preferably Julia (alternatively: MATLAB), and should be tested on models for oil/gas production.

Qualifications

  • Applicants to the PhD position must have a Master’s degree or equivalent higher education qualifications in Control Engineering /Engineering Cybernetics, or Applied Numerical Mathematics.
  • Excellent candidates with background in Chemical Engineering, Process Technology, Electrical Power Engineering, or similar, may also be considered.
  • The candidate should have some prior knowledge in dynamic models and control engineering, including basics of optimal control/MPC and Kalman filtering, as well as mathematical optimization.
  • A good command of numerical mathematics, (large scale) linear algebra, and efficient programming in script languages such as MATLAB, Julia, or Python is an advantage.
  • As part of the PhD work, publications are important, and efficient oral and written communication in English is therefore required.
  • It is a requirement that the successful applicant is granted admission to the university’s doctoral program in Process, Energy and Automation Engineering, thus a candidate must have an average grade B or better from the Master’s degree. The applicant must have gained the degree within the start date of the position, so applicants in the last semester of their master degree are also encouraged to apply.
  • This position is part of a larger project, so some co-operation with other researchers in the project is expected and Co-operation between staff members is an integrated part of the working atmosphere at the University of South-Eastern Norway.
  • Diversity in background for the project team is also important.
  • The candidate must be motivated and demonstrate a proven ability to work effectively within a team and in a collegiate manner to formulate and realize common objectives.

We offer

  • A stimulating and growing research environment, with good opportunities to develop your career and your academic skills
  • A good social environment
  • Attractive welfare benefits in the State Pension Plan
  • Opportunity for physical activities within working hours

Salary

PhD Research Fellow (code 1017): NOK 482 200 a year. Further promotion will be based on time served in the position. A statutory contribution to the state pension plan will be deducted from the employee’s salary.

Other information

The Academic Appointments Board for PhD Research Fellowships is responsible for the appointment. An expert assessment of applicants will be carried out. The candidates deemed best qualified will be invited to an interview.

The person appointed must comply with the laws, regulations and agreements that apply at any given time to the post. Please note that approved work permit is a prerequisite for the employment. A background check of relevant candidates will be performed.

According to its human resources policy, the University of South-Eastern Norway targets a balanced gender composition and aims to recruit persons with a background as an immigrant.

The Department has few women appointed in scientific positions, and women are therefore particularly encouraged to apply.
