چکیده

Because of low cost of alkaline, water flooding processes can easily be converted to alkaline flooding. In this paper we try to examine alkaline injection process in Haftkell field from the point of formation and its fluid that is oil and water. Before injection of the alkaline to the reservoir all effective parameters including temperature, presence of divalent ions, type of formation and other parameters should be considered in order to a principled design based on these parameters will be done. As we will see Haftkell field due to having carbonate formation and also having divalent ions makes some restrictions for alkaline flooding. If alkaline is injected to the reservoir that has limiting parameters not only does not improve production but as we will see will reduce production because of deposition creation, although it should be noted that alkaline will reduce the IFT with surfactant production that in this aspect reservoir oil must be at least have 0.5 of acidity number that could produce surfactant in contact with alkaline. In this paper alkaline injection process based on data from Haftkell field has been assessed completely.
