''Sidewall core analysis'' is performed on cores recovered by any of the sidewall coring techniques. Analysis is limited to basic tests for permeability, porosity, and residual fluid saturation.<ref name=pt05r38 />
''Sidewall core analysis'' is performed on cores recovered by any of the sidewall coring techniques.
Percussion sidewall cores from hard, well-cemented formations are badly altered during the coring process and generally fail to produce suitable measurements of mechanical and petrophysical properties.<ref name=pt05r38 /> Sample alteration may be reduced through the use of sidewall boring or a hydraulic press to collect sidewall core samples.<ref name=pt05r155 />
