Abstract | ||||
Faghur Basin is one of the most important hydrocarbon provinces in the northern Western Desert of Egypt. Some of the Mesozoic (Alam El Bueib and Khatatba formations) and Paleozoic rocks at this basin were evaluated as source rocks based on certain parameters including: the quantity, quality and maturation of the contained organic matter. PetroMode 1D software was used for the construction and prediction of geological and geochemical models. Results from organic geochemical analysis have clarified that the TOC, HI, S1, S2, %Ro and Tmax values of Alam El Bueib source rock units range from 0.27 to 6.39 wt.%, 34 to 114 mg/g, 0.12 to 0.38 mg/g, 0.23 to 4.3 mg/g, 0.58 to 1.07 % and 409 to 450 oC, respectively. While for the Khatatba source rock these values range from 0.41 to 30.09 wt.%, 27 to 155 mg/g, 0.1 to 0.53 mg/g, 0.15 to 26.41 mg/g, 1.02 to 1.09 %, 363 to 454 oC, respectively. As for the Paleozoic source rock they are ranging from 0.53 to 4.83 wt.%, 52 to 136 mg/g, 0.06 to 0.4 mg/g, 0.29 to 6.57 mg/g, 0.97 to 1.1 % and 406 to 467 oC, respectively. Such results indicate that the Alam El Bueib source rocks are characterized by type (III) kerogen while Khatatba and Paleozoic source rocks are of type (III) kerogen with inputs of kerogen type (II). Burial history analysis indicates that most of these source rocks are mature and reached their maximum temperature at Neogene time. | ||||
