TT Formation Damage Mechanism (Timmerman, 1982) Pressure profile in the formation Dp skin = Pressure drop across the damaged zone Skin or zone of damage
TT “ In must homogeneous matrix situations, the physical depth of solids invasion tends to be shallow (1-2 cm into the formation)” (Bennion et al., 2000)
