Structural interpretation of eastern Meyal area using 2D seismic data (T-1499) (MFN 3886)

Abstract

Meyal Oil Field, the study area, is located in district Attock near Pindi Gheb, the central part of Potwar plateau of Upper Indus Basin. The study area lies in the Himalayan collision zone between the Indian and Eurasian plates involving continuous uplifting, erosion and deposition of the sediments. Rocks from Pre- Cambrian to Quaternary age are present in the area. The Salt Range Formation is overlain by the Cambrian to Eocene platforms. The reflectors are marked with the help of formation tops of well Meyal-17 using VSP data. Interpretation of seismic lines shows the presence of a popup structure in the area. Popup structure is most likely to be the trap for the hydrocarbons. The Popup structure is east-west trending, gently dipping anticlinal fold, bounded by thrust faults. For the structural interpretation of the area, time and depth contour maps are generated. Correlation of Meyal-01, Meyal-17, Meyal-8P and Meyal-16(Ahmad, A., 2013), is made for the synthesis of subsurface structures between the wells. Attribute analysis suggests the presence of hydrocarbon at the Chorgali and Sakesar formations level.
