SYNTHETIC LOG TIE GENERATION OF KAILASTILA WELL 1 AND 2 IN SURMA BASIN FOR SEISMIC INTERPRETATION (Pages : 45 - 54)

The aim of the research work was to generate synthetic log tie. The application of the implemented log tie is provided better subsurface geology of the Kailastila area. The Kailastila well is located in Kailastila structure of eastern part of the Surma basin in the Bengal foredeep. In this paper synthetic log ties have been generated using different types of mathematical seismic source functions and layers velocities. Velocities are obtained from the well log parameters. Mathematical Gauspuls and dynamite source have been used as source function. Interval velocities and reflection coefficients are computed to implement the tie. Among the synthetic log ties, the tie developed with Gauspuls source and without interpolation is appeared suitable for the correlation and correction for interpretation. Interpreted sections are shown in this paper as well. Three prominent reflection bands are observed on seismic sections. The gas producing sands of the Kailastila structure belong to the Bokabil to Bhuban formations of Micene age. The generated log ties are also shown with seismic sections. Bared on the analysis of seismic sections and correlation with the well data, eight prominent reflecting horizons and five prospective sands layer are identified. This theoretical work has been performed at Geophysics lab in University of Rajshahi, Bangladesh. Download
