    Reservoir stimulation using matrix acidizing for carbonate formation in vertical oil well at X field in Libya.
    (Sebha University, 2017) Fathia Youssef Baraka, Fatima Abdullah Mousa , bannot Hassan Hamdo
    Formation damage is resulted from precipitation of salt materials due the chemical reaction in the well bore between either the Workover fluid or the formation fluid itself. This reaction causes a great reduction in the formation permeability in the vicinity of the well bore. This damage if not removed will cause a reduction in the oil productivity of the well and hence reduce the overall recovery from the well. Acidizing is one of methods used for removing this damage if the formed scale material is soluble in acid . If the scale is not soluble in acid, a conversion process will be made to convert the precipitant to another form of acid soluble compound or the removal of the scale is made by conducting a micro fracturing treatment to the formation in the vicinity of the damaged zone. The objective of this study is to determine the optimum acid injection rate needed to effectively remove formation damage from artificially damaged carbonate using 7% hydrochloric (HCl) solution concentrations. The significant improvement in the well production. Which is located in one of the fields of Libya and treated the well with acid according to the results of the survey of the registry increased the new productivity index.These results indicate that successful stimulation can be achieved at moderate injection rates when its compared between the two wells.Noted that there was a significant improvement and increase in production and cover the period Guaranteed full time guaranteed.
