Abstract
This thesis aimed to: 1) Quantify the processes of oil and gas generation, expulsion, and migration of Shoab Ali Oil field utilizing PetroMod software. 2) Give a proper appraisal of the geologic situation integrated with a comprehensive petroleum characterization model pointed to evaluate the petroleum system and hydrocarbon potential of Shoab Ali Oil field. 3) Explain the factors controlling the distribution of the different oil and gas fields at the same stratigraphic level. Integrated 1D basin modeling was applied to evaluate the thermal history of the sedimentary sequence in the Shoab Ali Oilfield. In all 1D models, the present-day heat flow is in accordance with temperature data and corrected bottom-hole temperatures from the available wells. Best accordance between measured and calculated present-day temperatures was achieved with present-day heat flows in the range of 63-76 mW/m2. The results of the 1D simulations show the differences in burial, thermal and maturity history. The burial history of the study area is represented by time-depth history plots that show the burial of different horizons traced through time, from deposition to present day. The subsurface temperature was specified for every layer throughout its geologic history.The following thermal regime for Shoab Ali Oilfield is proposed based on present-day corrected static bottom-hole temperatures: 1) Paleo-heat flow was highest at ~25-23 Mabp (the Oligocene rifting phase), with cooling caused by a heat flow decline. 2) Paleo-heat flow has increased during the Miocene rifting phase. This thermal scheme has been implemented in the 1D model, applying high heat flows from (~17.2 to 16.8 Mabp.) There was a decline in geothermal gradient due to rapid sediment accumulation (as indicated during the deposition of the South Gharib Formation) resulting in a subsurface temperature that was anomalously low. 3) Paleo-heat flow has increased during the Late Missianen Event from ~5.2-4 Mabp, and declining to the background in the Neogene.
