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
