Delineation of seismic reflectors in Miano area
Keywords:
Velocity analysis; Seismic time section; Seismic depth section; Synthetic seismogram; Miano.Abstract
The Miano area is located in lower Indus Basin of Pakistan. The research targets the method of seismic data processing and seismic data interpretation to delineate seismic reflectors using 2-D seismic and well data. Appropriate velocity formulas (root mean square velocity, interval velocity, average velocity and mean average velocity) are used in seismic data processing. The velocity analysis of the region show vertical and lateral variation in velocity. Second equation of motion is used to find depth calculation. Seismic interpretation has resulted in seismic time and depth sections, which helps to understand true picture of sub-surface. Synthetic seismograms are used to correlate the seismic reflectors, from comparison to the results from seismic data interpretation. The processing, interpretation and comparison results in six reflectors and are named as Siwalik, Ghazij, Upper Goru, top of Lower Goru, Chiltan Limestone and top of Jurassic.
