摘要: Petroleum well production impairment has long been associated with formation damage. Concepts such as the skin effect and its various manifestations have introduced to account for effects of The origins damage types also subjects intense scrutiny. Abatement included preventive measures use nondamaging fluids, presumably more benign processes, improved drilling construction procedures techniques. Once in place, removal spawned an entire industry, that matrix stimulation. This involves appropriate remediation complete understanding often contrasting interaction among these fluids damage, and, very importantly, side can than prestimulation state. Again, hardware was necessary. Owing fact is either incomplete or unsuccessful, methods bypassing high-permeability fracturing, developed. Finally, brute force approaches are common, including vertical and/or horizontal wells regardless order get enough production. paper a critical review both evolution technologies thought processes permeated industry over past quarter century. Particular emphasis given resolution controversial their impact on field. These include issues stimulation vs. sand control deconsolidation management, underbalance extreme overbalance, perforating practices.
