| Although the study of fluid inclusions was firstly used for assessment the genesis of ore deposits, but now this is extended to the various aspects of earth sciences, i.e., petrology, sedimentary rocks, tectonic, quality of ground waters as well as reconstruction of thermodynamic features of oil and gas reservoirs. Petroleum-bearing fluid inclusions (petroleum inclusions) are small aliquots of pore fluids trapped within the framework of rockforming minerals. These fluid inclusions typically range in size from <1 ?m to ~ 20 ?m and are present in a wide variety of different minerals (e.g. Burruss, 1981). Generally, the most of reservoir engineering studies especially those related to the primary and secondary migration of oil, correlation of geochemical data with reservoirs features, and tracing the migration paths of oil through fractures are very expensive. Accordingly, the petroleum inclusion technique could alternatively be used not only for reducing the costs but also to obtain the more accurate results. Petroleum inclusions offer direct evidence about the nature of pore filling petroleum at different times in the geological past. This makes them the witness of palaeo-fluid compositions during petroleum migration and accumulation, offering an opportunity to map petroleum presence and composition through time and space. The presence of petroleum inclusions indicates that petroleum was present in the pore space at the time that the host mineral phase formed or when a fracture was propagated through an existing mineral (Burruss, 1981; Burruss, 2003).This project needs detailed sampling from the cores of selected oil fields and then preparing thin and double polished thin section. Routine microthermometry analyses should be accompanied with laser Raman spectroscopy and UV-visible-NIR fluorescence microspectroscopy. Also, Gas - Chromatography- Mass Spectrometry is needed for geochemical correlation in the selected oil fields. In addition to these data, mineralogical properties (mineralogical paragenesis) and crystal-chemical characteristics (crystallinity, polytype and b cell dimension) of clay minerals should be investigated in order to understand basin maturation grade. The combination of results could provide valuable informations regarding the tracing of primary and secondary migration of oil from source rocks to reservoirs and between the selected reservoirs |
