It is situated in the northern region of the Gulf of Suez ' s Belayim Offshore Oil Field and is 4 km away from the Sinai coast. Water saturation is one of the steps through which the characterization of the reservoir and prediction of future accumulation are determined. Many parameters, such as types of shale, volumes of each type, and petrophysical exponents, are necessary to detect the accurate estimation of water saturation. First, Dia-Porosity crossplots are used to estimate three types of shale and their volumes (dispersed, laminated, and structural). From these plots, it was found that the dispersed shale exhibits the highest percentage in the middle of the study area, while the laminated shale volume increases toward the north directions, but the structural shales give the maximum value in the north-west trend. The presence of scattered shale in a formation is known to have a negative impact on the permeability of the rock, unlike the laminated shale, which decreases the total average of effective porosity. Comparable to laminated shale, structural shale has nearly identical characteristics. Second, the petrophysical exponents (cementation factor ( m ), saturation exponent ( n ), and tortuosity factor ( a ) were ascertained using Pickett ' s plot. It gave the values of m ranging from 1.8 to 2.3 and values of a varying from 0.72 to 1 in the studied wells, where these petrophysical exponents play a vital role for calculating the water saturation (Sw) in both clean and shaly rocks. This study aimed to determine the different types of shale and calculate the petrophysical exponents, which are important for a good estimation of the water saturation in rocks (clean and/or shaly) and for determining hydrocarbon saturation (Sh)","PeriodicalId":11625,"journal":{"name":"Egyptian Journal of Petroleum","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140733752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This oil re fi nery contamination was mostly the result of improper hydrocarbon disposal, which led to water leaks caused by equipment damage, vandalism, and accidents, which will ultimately pollute groundwater or release waste into the Gulf of Suez. Seven composite sediment samples were taken from a test plot. Total petroleum hydrocarbons were found in concentrations of 21.96, 23.58, 37.56, 54.48, 57.36, 33.96, and 23.04 g/kg, respectively. Hydrocarbons distribution were examined on a Hewlett-Packard (HP-7890 plus) gas chromatograph with a fl ame ionization detector. The resolved n-alkanes (R c ) were found to be 0.088, 0.087, 0.193, 0.091, 0.099, 0.123, and 0.177 m g/g. The results showed that the hydrocarbons are originated from terrestrial inputs. Several ratios of hydrocarbons indicated the predominance of petrogenic hydrocarbons. This was supported by high normalized aliphatic hydrocarbons concentrations; signi fi cant contributions of unresolved complex mixture; low n-alkane carbon preference index and even-to-odd carbon number predominance. Therefore, the chronic oil pollution in the area may be due to the large quantities of re fi ned products and the limited capabilities of water treatment units located in the studied areas.","PeriodicalId":11625,"journal":{"name":"Egyptian Journal of Petroleum","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140733079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methyldiethanolamine (MDEA) is a well-known tertiary amine used selectively for the removal of carbon dioxide from natural gas. There are many parameters that can affect the efficiency of separating these acid gases from natural gas. In this paper, we have studied, modeled, and optimized different operating parameters of sour gas feed and MDEA solution which affect the CO₂ recovery efficiency from an existing sweetening unit. These operating parameters are the sour gas feed temperature and pressure, volume ratio (%) of carbon dioxide in the feed gas, amine inlet temperature, and amine circulation rate. Actual data were collected from an industrial CO₂ sweetening unit over one year. These data were used to study the effect of the studied operating parameters on the recovery efficiency of CO₂ from the sweetening unit. All studied operating parameters were found to have an impact on the recovery efficiency of the removed gases. A response surface methodology approach was used in Design-Expert software version 13 to model the relationship between considered operating parameters and CO₂ recovery efficiency. In addition, Design Expert numerical optimization has been used to maximize CO₂ recovery efficiency. The results showed that the optimal range of sour gas feed temperature is 34.71 to 45.56 °C, sour gas feed pressure is 8.32 to 10.04 barg, the volume ratio (%) of carbon dioxide in the sour gas feed is 8.51 to 10.15, the temperature of the amine is 38.03 to 43.96 °C, and the amine circulation rate is 788.39 to 1122.35 m³/h.
