IGCCS: Induced-seismicity geomechanics for controlled CO2 storage in the North Sea is a research project funded by The Research Council of Norway (CLIMIT, KPN), led by NGI (Norwegian Geotechnical Institute). For this project we are seeking a two-year postdoc over the period of 01. January 2018 to 31. December 2019.

NGI is a leading international center for research and consulting within the geosciences. The subject research will be done within NGI's Department for Petroleum Geomechanics and Geophysics (PGG).
Post-doc CO2 storage
Application due: 8/1/2017
The project
In order to contribute to CO2 emission reduction, Norway will launch large scale CO2 storage projects in the North Sea in the near future. Monitoring is needed to ensure safe operation and avoid leakage of CO2 to the sea surface. In this project we evaluate the feasibility of microseismic monitoring for CO2 injection for storage candidates in the North Sea. This will require a high-level understanding of subsurface with respect to geomechanics and microseismics.
 
We will perform advanced laboratory tests in combination with numerical simulations at field scale. The laboratory work includes acoustic emission tests to simulate microseismic effects at the laboratory scale. Experiences from lab will be scaled up and applied to field scale through numerical analysis. Cores to test are sandstones and mudstones with stress and pore pressure conditions representative of those for the North Sea.
 
We also focus on the following mechanisms: 
  1. differences between two injections of CO2 and brine
  2. thermal effects resulting from the injection of cold CO2 into hot reservoir rock.
 
Finally, the outcomes should be able to be implemented into existing industry workflows. The scope of work in the project is established to fulfil the needs mentioned above, and to tackle the following questions:
  1. How is CO2 affecting rock deformation/failure and corresponding microseismic response in reservoirs and sealing units in the North Sea?
  2. How can we optimize monitoring systems and data analysis to ensure safe injection of CO2 in the North Sea? 
 
The project consists of 3 scientific parts (WPs):
  • WP1: Acoustic emission rock mechanical tests and material models
  • WP2: Coupled geomechanics modelling of CO2 injection-induced microseismicity
  • WP3: Application to field-scale monitoring  
 
The work will be performed by researchers from NGI, NORSAR, University of Oslo, CSIRO from Australia, and National Oceanography Centre in the UK. The project period is from May 2017 to June 2020.
 
Post-doc position and qualification
The two-year postdoc position is expected to perform key activities in IGCCS. The activities include laboratory acoustic emission test, advanced geomechanics modelling, microseismic data modelling and interpretation. The candidate is desired to have a completed PhD in either geophysics or geomechanics and dedicated scientific interests in the area(s) of acoustic emission testing, geomechanical material modelling and/or microseismic data analysis, importantly and preferably, with skilled acoustic emission (AE) laboratory experience.
 
The candidate must be able to carry out independent scientific research work including writing publications as well as practical skills for working in the laboratory. Fluency in written and spoken English is required. Emphasis will be placed on personal suitability as well as on genuine enthusiasm for the topic.
 
The main workplace will be at NGI in Oslo, and with a shorter period at CSIRO in Perth, Australia. The application (through our electronic application system - see link below) should include: 
a cover letter summarizing qualification and motivation for applying [1 page],
Curriculum Vitae [4 pages], including a publication and conference presentation list
copies of relevant PhD certificates
the names and contacts of 3 references.
