SEISMIC REFLECTION DATA INTERPRETATION, PETROPHYSICS, WELL CORRELATION AND FACIES MODELING OF BLOCK (20) OF MIANO AREA

Abstract

The study area is Block-20 Miano, and is located in Sindh province of Pakistan. It is present at the boundary of lower and central Indus Basin. The study area covers 2D vintage (1992) seismic time profile data of 8 migrated seismic lines (SEGYFormat) and seven wells (LAS files). The area has been identified as extensional regime. The main reservoir in the area is Lower Goru Formation especially its B Sand interval. Geophysical study includes the interpretation of seismic time profiles. Six horizons i.e. Sui Main Limestone, Rani Kot, Upper Goru, Top of Lower Goru, C-sands, B-sands are marked on the seismic sections with the help of well top data and synthetic seismogram of Miano-08 well. On the interpreted seismic sections, the horst and Garben structures are observed, Time and depth contours and surface of Rani Kot Formation are formed. Well log correlation and facies Modeling is also performed to determine the behavior of deposition. Petrophysical studies of include the determination of the porosities, resistivity of water, saturation of water, porosity,. The results show the presence of clean Sandstone and which may have ability to act as reservoir
