Abstract
We analyze geological, petrophysical and geomechanical characteristics of a $CO_2$ sequestration test site, Pohang. The target reservoir exists at a depth of 750 m, where porous and permeable sandstones/conglomerates prevail. The reservoir is underlain by thick mudstone formations. We estimate in situ stress conditions using an exploratory wellbore drilled through the target reservoir. The in situ stress condition is characterized by a strike-slip faulting favored stress regime. We discuss various aspects of reservoir fracture pressures and fault reactivation pressures based on the stress magnitudes.
