Geological and field factors impacting well acid treatment at Vatyegan field

Several oilfield, geological and physical factors have been identified. The y serve to provide more grounds for bottomhole treatment performance using various acid compounds. The paper shows impacts of oil flowrate, water cut, well killing count prior to treatment, formation stratification and sand c ontent, porosity ratio, permeability, and oil saturation, on treatment resu lts. The paper identifies most effective applications for salt- and clay-ba sed treatment methods, along with feasibility of nonionic surfactants and o il-wetting agents.
