Valhall 4D (2003-2019)

Abstract

Timeshift calculated from modelled strain using the TOE model show good qualitatively agreement with Timeshift from seismic in period 2003 to 2019
• R-factors calculated from modelled strain and TOE model show
‒ Dependency on strain calculation method
‒ Dependency of using local velocity change versus time shift
‒ Dependency of polar angle
• Using one average value for R-factor and local axial strain from geomechanical model shows good agreement with relative vertical velocity change
