Structural interpretation of western Meyal area using 2D seismic data (T-1496) (MFN 3890)

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. 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. The reflectors are marked with the help of formation tops of well Meyal-17 using VSP data (Ellahi, 2013). For the structural interpretation of the area, time and depth contour maps are generated. Correlation of Meyal-01, Meyal-17 (Ellahi, 2013), Meyal-8P and Meyal-16 is made to for the synthesis of subsurface structures between wells. Attribute analysis suggests the presence of hydrocarbon at the Chorgali Formation and Sakesar Formation.
