2D SEISMIC INTERPETATION ALONG WITH PETROPHYSICAL ANALYSIS, ROCK PHYSICS AND SEISMIC ATTRIBUTES OF BADIN BLOCK PAKISTAN

Abstract

The present study relates to the structural and Stratigraphy interpretation, attributes evaluation, petro physical evaluation and estimation of rock physics of Badin region. The facts used for this observe includes seismic statistics, navigation records and nicely logs facts. Badin place is distinguished within the lower Indus Basin for its hydrocarbon (oil and gas) structural traps. The Seismic lines had been obtained and processed with the aid of POL. For interpretation of these seismic traces two reflectors and normal faults were marked via the usage of the interactive tools of Kingdom software , polygon creation, two way time contour and depth contour are also the a part of the seismic data interpretation. The marked horizons were diagnosed the use of formation tops from wells and their depths were confirmed through correlation with synthetic seismogram from Density log (RHOB) and sonic log. From time and depth grids time and intensity contour maps of the horizons which are marked have been generated to understand the spatial geometry of the structures and the nature of geological structures as diagnosed by the seismic section of the area. Normal faulting as recognized on seismic sections confirmed that look at location lies in extensional tectonic regime. The resulted seismic interpretation of those lines confirmed Horst and Grabben structures by way of normal faulting. Horsts or the extended portions within the structure are suitable vicinity for the accumulation of hydrocarbons. Seismic attributes analysis of seismic section allows in figuring out the exclusive lithological limitations and also confirmed the structural disturbance. through the usage of properly data estimation of rock physics and petrophysical evaluation also are feasible for identity of accumulation of hydrocarbons. Facies analysis is done by means of the use of properly log data for figuring out the versions within the lithology of reservoir rock and also for marking the viable zone of hydrocarbons accumulation
