The oil industry is looking for a way to develop reservoir management and optimal production of hydrocarbon reservoirs. The use of advanced technologies in the extraction of oil and gas reserves is very important in advancing the short-term and long-term goals of this industry, both in terms of product type and process. A technology roadmap is a plan that implements short-term and long-term goals by using technology solutions to help achieve the goals;
; The technology roadmap for in Enhanced Oil Recovery (EOR)/ improved Oil Recovery (IOR) oil fields has been developed based on the emphasized fields and areas of the target technology and has been expressed in a ten-years according to the existing challenges and preventive measures, and all research and executive activities will be carried out with the focus on the roadmap.
In this research, using the case study research method, by studying 9 cases of research conducted in the research and technology of the National Iranian Oil Company, a map of executive achievements and technological solutions in each of the target technology areas: reservoir, well and The facilities have been identified and presented based on the challenges and implementation stages. The results of this study show that in this roadmap, the issue of creating, developing and equipping specialized centers for EOR, raising skills, expertise and knowledge and transferring technology as achievements Sustainability is key and in addition to other achievements, outputs and results of each stage and technological solutions to challenges has been highly emphasized and important

The Asphaltene and metal naphthenate components of crude oil samples from ten different wells within an oil reservoir were determined using different analytical techniques. The asphaltene content was determined by gravimetric analyses while the metal naphthenate components were determined by obtaining the metal ion concentration of the produced water and the naphthenic acid concentration of the crude using Atomic absorption spectrometer (AAS) and potentiometric titration respectively. Results obtained showed that the asphaltene content of the crude samples ranges from 2.0000 – 8.000 %w while the naphthenic acid concentration indicated by the total acid number (TAN) ranges from 0.3000 – 1.4600 mg/KOH/g. All the crude samples possess asphaltene components as well as the propensity to form calcium and sodium naphthenate scale deposits having a Ca2+ concentration between 32.5000 – 94.5000 mg/L and a Na+ concentration between 27.7 – 105.1 mg/L respectively, however the formation of naphthenate scale deposits is highly dependent on the pH of the produced water of the crude which makes well FT01 less likely to form naphthenate scales since it has a pH < 6. Both asphaltene and naphthenate deposits are directly proportional to the specific gravity of the crude and inversely proportional to the API gravity implying that both components reduce the quality of the crude. Asphaltene and metal naphthenate solid deposits in the crude can cause a lot of flow assurance difficulties such as, blocking of expedition lines, pore plugging, wettability, crude oil parameter alteration, as well as reduction in oil recovery.
