Therefore, in this research, methods of controlling the occurrence of corrosion in the crude oil refining unit in the Najaf refinery for four types of crude oil - API (28, 28.2, 29.2, and 30.2) were studied. Chemicals were added in different quantities and types before and during the crude oil refining process to the atmospheric distillation unit, where it was found that these chemicals have the ability to make a media within the limits of pH from 5.5 to 6.5, where the corrosion became little or no. Also, an anti-corrosion chemical was added, which reduced the incidence of corrosion in the overhead systems of crude oil refining equipment. In addition to treating the crude oil using desalter before refining it, where the mud and dirt and a large proportion of the salts in the emulsified water were removed from crude oil. The best results obtained were pH (6, 6, 5.7, and 5.5)  and the percentage of iron ions Fe+2 ( 0.8, 1, 1.5, and 2.1) for four types of refined crude oil at using pump dosages for inhibitor (2.5, 2, 3.5 and 3.5), caustic soda (4, 6, 8, and 8) and neutralizer (2, 2.5, 3, and 3).

One of the most important types of turbines is the gas turbine, which is frequently used in oil depots. One of the remarkable depots in Iraq is Zubair-1 / Basra that exports around 850,000 barrels per day (B/D). Therefore, Zubair-1 should continue pumping the crude oil 24/7, which has five gas turbines (three Rolls-Royce AVON MK 1533 and two Siemens SGT 400). However, the three Rolls-Royce gas turbines in Zubair-1 have not worked in the summer season since 2016, when the ambient temperature goes high around 11:00 am to 3:30 pm. This paper proposes solution to solve a high exhaust temperature (EGT) shutdown signal (a preventing running turbine signal) without effect on the sequence of turbine running stages. The proposal is adding a fuzzy inference system (FIS) that controls the gas turbine in the first two running stages that demonstrates and controls of speed the turbine from 800 RPM to 3000 RPM. The inputs of FIS are the average temperature of eight combustion chambers (exhaust temperatures) and the speed of the gas turbine, while the output of FIS is the control signal to the flow control valve (FCV) with an amplifier to gain the signal. \u0000The FIS proposal has been applied in all three Rolls-Royce jet pumping turbines since April 7, 2021, and they work regularly at all times of the day.

A three-dimensional geological model of the As reservoir in AG oil field was used to see the influence of these factors on cumulative oil production and NPV. After creating the dynamic model for the As reservoir using the program Petrel (2017.4), we improve the robustness of forecasting production from smart wells using reservoir simulation. High-level details in the rock and fluid flow properties are required in the horizontal well region to capture the flow dynamics accurately.
