Integrated Approach to Acid Treatment Optimization in Carbonate Reservoirs

摘要

This paper describes an integrated approach to stimulation treatment design for carbonate reservoirs. When given a choice in the technology of well acid stimulation in a carbonate reservoir, the use of an integrated approach to reagent selection and treatment design is necessary. Accounting for the properties of acidic compounds for specific geological and physical conditions increases the efficiency of the well bottom zone stimulation because of a larger radius of influence, which prevents the formation of insoluble compounds and bridges the pore space of this zone. Results of the determination of the kinetic parameters and characterizations of the rate of the acid composition reaction with oil- and water-saturated rock samples are given.
