Oil production and Drilling of an oil field formation is the only convenient way to transfer the oil from the reservoir to the well head surficial facilities. According to the various stages of drilling operations, formation damages are playing an important role in reducing the rock permeability. In this occasions, the accurate measurements must be taken to increase permeability of the fractured carbonated reservoirs. Therefore, oil could be easily moved through the formation layers and cracks. Moreover, steep rising in the rate of oil production may be another method of stimulating the well. The greatest appeal technique for optimizing the recovery factor in terms of increasing the productivity rate is the acidizing procedures that administered to the carbonated reservoir rocks. In this research, the techniques of acidizing due to increasing the permeability of the reservoir rock is being investigated and the differences between the types of applied methods are being demonstrated. That is to say that, these performances might cause to erode the welfare of a reservoir rock or erode a segment of the rock which collapse the acidizing channels. Consequently, acidizing could be applied to eliminate the emulsion which was formed in the open and close channels to block out water trapped in the rock. This method in carbonated reservoirs when the fracture produce by Heavy liquids could reduce the acid pressure.
