Formation Damage is a condition which occurs when barriers to flow develop
in the near-wellbore region to give rise to a lower than expected production rate
from or injection rate into a hydrocarbon bearing reservoir rock. The reservoir
rock, its constituent minerals and resident fluids are essentially in a state of
physical, chemical and thermodynamic equilibrium. As reservoir rock is penetrated
that equilibrium is disturbed and formation damage can occur. This problem has been
recognized for several decades as a major contributor to anomalous production and/or
abnormal decline in productivity or injectivity in most hydrocarbon reservoirs.
