Job description

The positions are part of the project “Geophysics and Applied Mathematics for Exploration and Safe Production”, funded by The Research Council of Norway. The main topics of the project are methods for data assimilation and efficient monitoring in geosciences applications. The candidate is expected to conduct research in one of the areas of the project under the supervision of a permanent member of the acoustics group participating in the project.

PhD 1: In recent years several of the major hydrocarbon fields offshore Norway have been equipped with permanent seismic sensors that are trenched into the seabed. Repeated seismic surveys are shot over these receiver arrays typically two times per year, in order to detect and monitor reservoir changes related to production. This new type of acquisition makes it possible to develop new methods and algorithms to improve this 4D mapping process. The use of advanced mathematical inversion algorithms and exploiting long offset data is one such example. Another example is to couple typical production effects (such as saturation changes, pressure changes or compaction) to observed changes in the seismic data. The aim is to test such couplings at different levels: fully integrated in a mathematical inversion procedure, or a more stepwise and simplified manner requiring less computational cost. This position requires a good knowledge in geophysics and/or mathematics/physics.

PhD 2: This position will focus on overburden changes that can be illuminated by the use of repeated seismic data. Detailed analysis of interface waves and their corresponding dispersion behavior will be a key part of the work. Can a combined use of reflection seismic and interface waves give a more precise way of monitoring changes in the rocks above a producing hydrocarbon reservoir? We propose to develop new techniques to detect and map early leakage of for instance gas from a hydrocarbon reservoir or CO2 from a CO2 storage site. Forward modeling of both reflected seismic data and especially the interface wave at the seabed (often referred to as the Scholte wave) will be crucial. This position requires a good knowledge in geophysics and/or mathematics/physics.

Qualification requirements

The PhD-position's main objective is to qualify for work in research positions. The qualification requirement is completion of a master’s degree or second degree (equivalent to 120 credits) with a strong academic background in geophysics, underwater acoustics, signal theory, physics or mathematics or equivalent education with a grade of B or better in terms of NTNU’s grading scale. Applicants with no letter grades from previous studies must have an equally good academic foundation. Applicants who are unable to meet these criteria may be considered only if they can document that they are particularly suitable candidates for education leading to a PhD degree.

The appointment is to be made in accordance with the regulations in force concerning State Employees and Civil Servants and national guidelines for appointment as PhD, postdoctor and research assistant

Other qualifications

We are looking for highly motivated candidates with strong background and interest in geophysics, physics or mathematics. Knowledge within computing and writing computer code is required.

MSc students who expect to complete their master’s degree studies by summer 2019 are also encouraged to apply. Employment will then be postponed until the master’s degree is finished.

The applicants who do not master a Scandinavian language must document a thorough knowledge of English (equivalent to a TOEFL score of 600 or more).

The appointment is to be made in accordance with the regulations in force concerning State Employees and Civil Servants and national guidelines for appointment as PhD, post doctor and research assistant.

Personal characteristics

  • Curious, innovative person
  • Scientific communication skills
  • Ability to put thoughts into written material 656

In the evaluation of which candidate is best qualified, emphasis will be placed on education, experience and personal suitability, as well as motivation, in terms of the qualification requirements specified in the advertisement
