Laboratory and field studies indicate that almostevery operation in the field, such as drilling, completion,workover, production and stimulation are potential sourceof damage to well productivity. Formation damage haslong been recognized as a source of serious productivityreduction in many oil and gas reservoirs. The mud cakeis a damage that occurs in formation caused by drillingprocess. Prevention of formation damage has the fol-lowing advantages: a) To reduce ultimate comple-tion costs; b) To preserve barriers; c) To improvesweep efficiency.
