Abstract
Four Egyptian crude oils were collected from four oil fields namely, Shokeir-22, West Ashrafi, Hana-3 and Arta-4 and characterized through petroleum measurements and chromatographic analysis. The oil samples from Shokeir-22 and West Ashrafi locate in marine source at the southern province of Gulf of Suez while the oil samples Hana-3 and Arta-4 locate in the desert at the middle province of Gulf of Suez. The physicochemical properties of the studied crude oils were achieved using standard test methods (ASTM, UOP and/or IP). The four crude oils were distilled to 200 oC, then the residue over 200 oC was fractionated into its components, hydrocarbon types and classes, namely asphaltens, resins, saturates and aromatics on alumina column chromatography and the aromatic fraction was fractionated into its components, namely mono-, di-, and poly aromatics on silica column chromatography. The studied oil samples from Shokeir-22 and Hana-3 that have low amount of water were distillated to isolate their technical fractions, gasoline (Initial-150 oC), kerosene (150-250 oC), gas oil (250-300 oC), lubricating oil (300-370 oC) and residue (over 370 oC) according to ASTM-D2892 and the physicochemical properties were determined for each fraction and the hydrocarbon types of gasoline and kerosene were determined while the residues (over 370 oC) were fractionated into their hydrocarbon types and the separated waters from West Ashrafi and Arta-4 crude oils were analyzed. The poly aromatic fractions of the four oil samples were analyzed via high performance liquid chromatography (HPLC). The paraffinic fractions of the four studied crude oils were subjected to Gas chromatography-Flame ionization detector (GC-FID) to determine the carbon distribution of normal and branched paraffinic hydrocarbons and physicochemical properties to study source and composition of crude oil then they subjected to Gas chromatography-Mass spectrometry (GC-MS) to determine the biological marker compounds (steranes and hopanes) to characterize the type of organo-facies, oil classes, depositional environments and the degree of thermal maturity of the crude oils.
