Özet

© 2020. All Rights Reserved.Seismic interpretation delineates the subsurface features (structural and stratigraphic) that are favorable for hydrocarbons' accumulation and Petrophysical analysis evaluates the reservoir characterization in detail. In this paper, 2D seismic data of the Hala area is used to study the structural traps that may be favorable for hydrocarbons. AdamX-01well in the study area is producing. Petrophysical and facies analysis give information about the reservoir parameters. Interpretation incorporates well data. Sands of Lower Goru Formation (Cretaceous) act as a reservoir. Horst and Graben subsurface geological structures are delineated at reservoir levels by using TWT and depth structures maps. Chiltan Limestone Formation (Jurassic) is also marked and contoured in time and depth domains. The petrophysical analysis gives two potential zones with high hydrocarbon saturations. Facies modeling confirms reservoir sands. Integrating the geophysical techniques, possible hydrocarbons, and new potential zones are identified.
