Abstract

Summary

In the context of urgent response need to global warming and CO2 capture regulation, the Smeaheia fault block, offshore Norway, is an anticipated location for CO2 storage where the Jurassic Krossfjord, Fensfsjord and Sognefjord formations are identified as possible CO2 reservoirs. This work is the sequel of a previous case study where the environments of deposition were scrutinized through attribute mapping analysis on geological surfaces derived from a semi-automatized seismic interpretation and geological model creation workflow. In this new stage, after having reviewed the seismic interpretation and derived model, we establish a velocity model to convert the GN1101 seismic volume and interpreted reservoir top and base surfaces from time to depth domain. These depth-converted geological surfaces allow to precisely locate the potential traps intersected by the GN1101 cube and work out different Gross Rock Volume estimation for the CO2 entrapments following 2 distinct scenarios. This way, we show that a comprehensive classic seismic interpretation workflow remains perfectly suitable for CO2 storage appraisal.
