SINTEF is looking for a postdoc in geophysics

We are looking to strengthen the Applied Geoscience group in SINTEF Industry with a postdoctoral researcher within geophysics. Do you want to join our team?

The Applied Geoscience group combines expertise in geology, geophysics, and reservoir technology. In addition to having a long track record of developing solutions for the oil and gas industry, we have a large research portfolio within CO2 storage and environmental geoscience.

We are looking for an ambitious researcher to join our geophysics team as a postdoc, which also provides an opportunity to later apply for a permanent position. As a part of a strong research environment, you will work directly with researchers in the group and cooperate with our colleagues in other institutions. The main topic of the work for this position is the use of controlled source electromagnetic (CSEM) technology for CO2 storage monitoring.

You should hold a PhD in geophysics, applied mathematics, data processing, or other relevant subjects. Advanced skills in scientific programming and numerical methods are required.

The following qualifications are viewed as especially relevant:

  • Experience with electromagnetic techniques
  • Competence/experience within programming and development of numerical tools (e.g., for wave propagation modelling, machine learning, or data processing)
  • Interest in or relevant experience from the petroleum industry or within R&D for CO2 storage
  • Experience with applied research

We are looking for a person who

  • Cooperates well
  • Maintains progress and delivers reliably
  • Is engaged, curious and ambitious
  • Is self-propelled, flexible, and able to learn
  • Is accurate and structured
  • Communicates well both orally and in writing.

We offer:

  • Exciting and collaborative work in an international environment in continuous development
  • Great possibilities for professional and personal development in an organisation where responsibility and initiative are highly appreciated.
  • Flexible working hours, salary based on qualifications, day care, attractive pension and insurance schemes

Duration: 2 years

Does this seem interesting and attractive? Then we are looking forward to your application!

We would like the candidate to start as soon as possible. For more information, please contact Research Scientist Anouar Romdhane, SINTEF Industry (tel. 450 95 746). A more thorough project overview with a description of the research activities is given below.

Project description:

An accurate and efficient monitoring strategy is essential for safe CO2 storage in compliance with laws and regulations. The reliability of the monitoring technology is also crucial for the public acceptance of carbon capture and storage (CCS), especially in case of large-scale import and storage of CO2 from other European countries. The cost of a comprehensive monitoring program covering the different phases of a storage project could, however, quickly become prohibitively high, if not carefully optimized.

While expensive seismic surveys will most likely be the backbone of any geophysical monitoring program, controlled source electro-magnetics (CSEM) can be a cost-efficient and valuable complement. By providing an additional, yet essential, earth parameter (resistivity) as well as additional information about anisotropy, CSEM significantly constrains estimates of the pressure and, especially, the saturation changes. The improved capability of quantitative characterization will reduce risks and support the development of better tailored, sparser (in time and space) geophysical surveys and will consequently help to reduce costs. The resolution of EM is inherently lower than that of seismic and therefore the resolution capabilities, time-lapse approaches, and optimum ways of combining seismic and EM should be carefully investigated.

The postdoc will be a part of the CLIMIT project "Accelerating CSEM technology for efficient and quantitative CO2 monitoring" (project number 281839) lead by SINTEF, with NGI, The University of Southampton, and UiO as partners. It is a spin-off project from the Norwegian CCS Research Centre (NCCS). The project goal is to study the use of CSEM technology for CCS. Thus, the postdoc will collaborate with several of these institutions during the project.

The postdoc will focus on the following three main activities:

Time-lapse inversion techniques: develop and implement a tailored time-lapse inversion method for CSEM. A review and evaluation of different proposed time-lapse approaches will be performed first. During the method development the focus will be on: (i) the feasibility of reconstructing the resistivity changes due to CO2 injection, (ii) address challenges related to repeatability and limited resolution, (iii) define optimum strategies for resistivity monitoring by incorporating available prior information and its uncertainty, and (iv) evaluate uncertainties in the reconstructed resistivities. In addition, the use of machine learning (ML) will be investigated. By training the network on vintage data, the possibility of fast-track inversion of later more sparsely acquired monitor data will be tested out.

In this main activity the postdoc will collaborate closely with SINTEF and NGI.

Optimal rock-physics models and inversion: develop optimal rock-physics models for conversion of CO2 properties and bearing rock properties into resistivity and seismic attributes. Using appropriate well log and laboratory data, rock-physics models will be built linking the most important rock-physics properties such as partial saturations, porosity, pore pressure and CO2 phase properties to resistivity, bulk density and seismic velocities and impedances.

In this activity the postdoc will collaborate closely with SINTEF, NGI and University of Southampton.

Case study for baseline, monitor and time-lapse surveys: in this third main activity the methodologies and models developed in the previous two main activities will be made use of. The final goal will be to deliver CO2 saturation and possibly pore pressure mapping after CO2 injection using appropriate rock-physics models and CSEM and seismic inversion results as input data.
