The current work combines well logging and core data analysis to precisely estimate petrophysical parameters and evaluate the Mamuniyat reservoir. The available data includes well logs from eleven wells and core data from one of the studied wells (I-14 Well). Utilizing well logs and core data, the Mamuniyat Formation is found to be made up of sandstone with a low shale content between 5 and 10%. It has effective porosity values that vary between moderate (13%) and good (16%), with oil saturation ranging from 62 to 91%. Using core data analysis, it was found that the grain density is 2.65 g/cc. A good match between the core-derived and log-derived porosity values is observed. It could be concluded that the Mamuniyat Formation is a sandstone reservoir with low shale volume, moderate effective porosity, and high oil saturation. The reason for the large number of dry holes in Murzuq Basin could be attributed to other factors other than reservoir quality.","PeriodicalId":14847,"journal":{"name":"Iraqi Geological Journal","volume":"87 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140476164","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}

Throughout June and July 2022, thirty samples of dust were taken from eucalyptus leaves. These samples were collected from various locations including industrial areas, streets, parks (green areas), and residential sites. The concentration of heavy metals including As, Cd, Co, Cr, Cu, Mn, Ni, Pb, V, and Zn was determined using Inductively Coupled Plasma – Mass Spectrometry (ICP-MS). To assess the contamination level of the dust with heavy metals, various indices and models were utilized; these included the geo-accumulation index (Igeo), enrichment factor (EF), contamination factor (CF), and pollution load index (PLI). In addition, the Potential Ecological Risk Index (RI) and health risk assessment model were evaluated using the Hakanson and USEPA methods, respectively. The findings revealed that the metals' concentrations followed a descending order of Mn> Zn> Ni> Cr> Cu> V> Pb> Co> As> and Cd. The Igeo data showed that the dust in the area of study was clear of As, Co, Cr, Mn, Pb, and V pollution, unpolluted to moderately polluted with Cd, Cu, while moderately polluted with Ni, and Zn. The CF results indicated that the degree of dust pollution was low for V, moderate for As, Cd, Co, Cr, Cu, Mn, and Pb, and considerable for Ni and Zn. According to the EF calculation results, As, Cd, Co, Cr, Cu, Mn, Pb and V all have deficiencies or very minimal enrichments, but Ni has a moderate enrichment and Zn has a moderate to significant enrichment. The Er values exhibited that the Er was classified as low potential risk for As, Co, Cr, Cu, Mn, Ni, Pb, V and Zn except Cd which indicate moderate potential ecological risk. The RI value is classified as low ecological risk for heavy metals in all sampling sites. The results of the health risk assessment revealed that the examined heavy metals pose no non-carcinogenic danger to children and adults, while Cd, Co, Ni, and Pb do not represent a carcinogenic danger to children or adults. The risk of As and Cr on human being is within acceptable limits.","PeriodicalId":14847,"journal":{"name":"Iraqi Geological Journal","volume":"595 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140470973","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}

To minimize these problems, drilling fluid can be used to solve it. Wellbore stability analysis is critical to minimizing Non Productive Time and drilling costs in the East Baghdad Oilfield. Tanuma and Zubair formations are challenging formations due to shale-fluid chemical interaction. The present study aims to investigate the properties of shale samples and develop drilling muds through laboratory tests. The shale's physical attributes were analyzed using a stereomicroscope and scanning electron microscope to figure out its structures. Cation exchange capacity and capillary suction timer were also conducted to analyze the shale reactivity and select the shale inhibitors. Based on these tests, four drilling muds with unique additives were formulated, and their efficacy was verified using the linear swelling meter and the hot rolling experiments. The results showed a consistent and immediate interaction between the shale and various drilling fluids. A comparison was made between the first and second muds for Tanumah and Zubair formations, it was discovered that water-based muds1 exhibited greater swelling than water-based muds2, where swelling ratios for Tanuma shale units were 6.1% for water-based muds1 and 3% for water-based muds2. In comparison, for Zubair shale units, they were 3.01% and 1.53%, respectively. It is recommended to add 7% KCl to Tanuma mud and 3% KCl to Zubair mud as optimum additives with polypeptide hydration suppressants for inhibiting shale swelling and reducing its risk. This study's findings can contribute to the development of drilling muds that address shale instability concerns and thus minimize drilling expenditures.","PeriodicalId":14847,"journal":{"name":"Iraqi Geological Journal","volume":"111 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140473706","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}

The Fatha Formation exhibited a high gypsum rate due to the presence of gypsum layers. Strong positive correlations were observed between gypsum and sulfate, as well as between electrical conductivity and total soluble salt.
