[Abstract] Formation damage, a reduction in the natural capability of a reservoir to produce its fluids, such as a decrease in porosity or permeability, or both, can occur near the well bore face (easier to repair) or deep into the rock (harder to repair). Formation damage is caused by several mechanisms: 1- physical plugging of pores by mud solids, 2- alteration of reservoir rock wettability, 3- precipitation of insoluble materials in pore spaces, 4- clay swelling in pore spaces, 5- migration of fines into pore throats, 6- introduction of an immobile phase, and 7- emulsion formation and blockage. Damage can occur when sensitive formations are exposed to drilling fluids. In this paper we discuss about damage during drilling, completion, production, work-over, what is the influence on formation damage?, What properties most influence the effect of formation damage?, damage mechanisms and how does formation mineralogy and clay chemistry influence damage? What about fines migration, scale, paraffin and asphaltenes, damage prevention and damage removal?
