Formation damage occurs when fluids invade the section adjacent to the well bore, plugging the formation flow channels and reducing their natural permeability. In spite of the many stimulation techniques currently being applied, in most cases no more than 50% of the original rock permeability can be restored. Formation damage is caused by fine particles invasion and plugging, formation clay swelling, incompatible fluids, formation particles dislodging and movement, change in wettability, and emulsion or water blocks. New materials, techniques and equipment for drilling-in, completion, and workover with non-damaging fluids are discussed. 15 references.
