Query: Evolution of the Stress and Strain field in the Tyra field during the
  Post-Chalk Deposition and Seismic Inversion of fault zone using
  Informed-Proposal Monte Carlo   When hydrocarbon reservoirs are used as a CO2 storage facility, an accurate
uncertainty analysis and risk assessment is essential. An integration of
information from geological knowledge, geological modelling, well log data, and
geophysical data provides the basis for this analysis. Modelling the time
development of stress/strain changes in the overburden provides prior knowledge
about fault and fracture probability in the reservoir, which in turn is used in
seismic inversion to constrain models of faulting and fracturing. One main
problem in solving large scale seismic inverse problems is high computational
cost and inefficiency. We use a newly introduced methodology --
Informed-proposal Monte Carlo (IPMC) -- to deal with this problem, and to carry
out a conceptual study based on real data from the Danish North Sea. The result
outlines a methodology for evaluating the risk of having subseismic faulting in
the overburden that potentially compromises the CO2 storage of the reservoir.
