Characterization and Modelling of a faulted oil and gas field (Syria)
Not peer reviewed
MetadataShow full item record
The FC is a faulted oil and gas field located onshore, in the southeast of Syria along the Euphrates Graben. In the 2011, a static reservoir model was built by students of IFP School. The same database used in the 2011 model was using in the 2013 model (seismic data, well data, production information). Refinements and new interpretation were necessary in order to simplify the 2011 model and to prepare a proper case study dedicated to education. The 2013 model included structural, sedimentological and stratigraphical models, definition of facies and distribution of petrophysical properties to get a more realistic geological case. The model is likely more accurate because of the certainty of the data interpreted about thickness of the Lower Rutbah and Mulussa F clastic reservoirs, the structural framework, the environment of deposition based on core data, the correlation of the main maximum flooding surface and the property distribution in the reservoirs. The compartmentalization in the FC field is created for the normal faulting produced during the Upper Cretaceous. The main uncertainties are relateded to interpretation of the main reservoir due to the low resolution of the seismic information, depth-time conversion due to the only VSP information in one well over an area of 180km2.and variation in the thickness and in the areal extension of the reservoir. The 2013 model could be improved including a new seismic cube and more data from new well.
