Using Integrated Seismic Interpretation Methodology in the (Abo-Rabah) Hydrocarbon Structure Field
Main Article Content
Abstract
The purpose of this study is to identify the characteristics of Kurachine Dolomite reservoir rocks (KD), and the Kurachine Anhydrite cover rocks (KA) in the (Abo-Rabah) hydrocarbon field in the Ad-Daw Basin (central Syria). The reservoir and covering rocks, being the most important elements necessary for the presence of hydrocarbon traps. The study focuses on the reservoir Kurachine Dolomite rocks (KD), and the covering Kurachine Anhydrite rocks (KA) in the Abo-Rabah area in the Ad-Daw Basin (central Syria). The mentioned Kurachine formations consider to be favorite traps for hydrocarbon ac- cumulation in the (Abo Rabah) and adjacent area. A litho-stratigraphic model has been proposed for the study field, through analytical integration and interpretation processing. This model reveals differences between litho-stratigraphic relations in the concerned field. Most of significant reflectors in the district were investigated by transmitting the integrated seismic data into geological formations. Two Way Time (TWT) map of the reservoir formation (KD) has been originated. The comparison results of this study are with the previous results. It has been found that, the current prepared time map (TWT) is different from the previous maps, where the current (TWT) seems to be more realistic, because it is based on a larger number of boreholes, that are recently drilled in the study area. So, the reliability of the present results enabled to suggest three new promised hydrocarbon borehole locations favorable for drilling. Also, the current study exposed the relation between the clarity of the seismic signal and the thickness of kurachine anhydrite (KA) cover rocks.
