Improving CO₂ well integrity by studies of materials from Ketzin wells – Petrophysical characterization of core samples

Core samples from formation rock material have been made available from samples
collected during the drilling phase of Ketzin wells. The main focus of the petrophysical
characterization study has been to determine:
1. The capillary pressures
1a. Drainage and imbibition measurements for reservoir rock
1b. Entry pressure for the cap rock sample
2. Elastic and electric parameters with simultaneous CO₂ saturation images:
2a. Acoustic velocities, Vp and Vs
2b. Resistivity
