Abstract

The present Study pertains to the Structural and Stratigraphy Interpretation Ii I Attributes Analysis, and Estimation of Rock Physics of Safed Koh Block I I situated in Central Indus Basin. The Data used for this Study consists of SEG- I II Y data, Navigation Data and Well Logs data. Safed Koh area is prominent in the I Central Indus Basin for its hydrocarbon (Oil and Gas) Structural Traps. I I The Seismic lines were Acquired and Processed by Schlumberger and Dewan I I,: Petroleum Limited. For Interpretation of these Seismic Lines three Reflectors III ! and Reverse Faults were marked by using the Interactive tools of Kingdom : i! Software, Polygon Construction, Two ways Time Contour and Depth Contour iI I are also the part of the Seismic Data Interpretation. I I The Marked Horizons were identified using Formation tops from Wells ! I I .i, ~~m~~~~m ~~~h~en:i~e lo;o:;:)d an~~oo';;;~ ~;.r~~~~nT:::h .!r~~;: II:. ; Grids Time and Depth Contour maps of the Horizons that are marked were ' I i i generated to understand the Spatial Geometry of the Structures and the Nature I I of Geological Structures as identified by the Seismic Section of the Area. i I I Reverse Faulting as Identified on Seismic Sections confirmed that Study Area I lies in Compressional Tectonic Regime. The resulted Seismic Interpretation of I " these Lines confirmed Pop up Structures by Reverse Faulting. Pop up or the :1' . , elevated portions in the Structure are Suitable place for the Accumulation of ! I Hydrocarbons. I I I i I I I I Seismic Attributes Analysis of Seismic Section helps in identifying the different i Ii Lithological Boundaries and also confirmed the Structural Disturbance. By I I using well data estimation of Rock Physics is also possible for Identification of i I accumulation of Hydrocarbons. vii I
