Modelling: Sensitivity Study : Setup
Motivation:
Determine the influence of the various input parameters on saturation evolution,
pressure build up, storage capacity etc.
Setup:
• radial symmetric domain
(30m high, lateral extent 500m – 5000m)
• reservoir cap rock 730m below surface
• use characteristics of Ketzin site
(permeability, porosity, brine density etc.)
• injection of 1 kg/s supercritical CO2
in screened section of well (5m) for
2 years
