Because of the various factors such as the invasion of drilling mud filter during drilling operation , perforation, completion and also during production period of the well, the area around of the well is damaged which cause to reduce a large amount of pressure in the wellbore so the production of the well is reduced.To remove damage zone, acidizing is an effective method. In this paper , we study how the high volume acidizing is effective and what its effects on the elimination of damages are and if it affects the increasing of the production rate of the three wells of the Gachsaran's oil field or not
