2D Seismic Interpretation and Characterization of the Upper Qishn Clastics in Sharyoof Oil Field, Masila Basin, Yemen

Abstract

The Sharyoof oil field is located off shore in Block 53 in the northeastern part of the Syaun-Masilah Basin, in the province of Hadramaut, 550 km from the city of Sana’a, the capital of Yemen. Fifteen 2D seismic lines along with six wells data are used to construct subsurface geological profile, and to identify major structural features in the study area. Synthetic seismograms have been constructed using sonic and density log for all available wells to tie horizons to seismic data and to generate time and depth subsurface maps. This research has been carried out using integrated 2D seismic and petrophysical studies in Sharyoof oilfield. Using the analysis and interpretation of seismic data, the main structural faults were identified, maps of isochrones, structural maps of depth and thickness were constructed, which subsequently will allow us to correctly determine the deep geological structures in Upper Qishn Clastics member and evaluate the oil horizons of the Sharyoof oilfield.
