20 SEISMIC INTERPRETATION OF LINE # NP-84-44 & DISCRIMINATING THE RESERVOIR BY USING CROSS PLOTS

Abstract

This dissertation is based on the interpretation of 2D Seismic reflection data. Seismograph service limited acquired the data in the Ratana Area in Apri I 1985 by using suitable recording parameters. The data passed through a desirable processing sequence and finally a time section was prepared. A time section is produced from the seismic section using the VP points and the twoway- times (TWT) of the reflectors and faults. These average velocities are then used to find the depths of the formations for the Geoseismic Section or Depth Section. The seismic section is recorded for 4.6sec. The line NP84-44 is strike line. The direction of the strike lines is NNWSSE. The section Gomprised of a total of Vibroseis points from VP-200 to VP- 444. Three prominent reflectors are marked on the seismic sections on the basis of observed reflection events. The marked horizons show deformation in the area caused by compressional tectonics. Pop up structures are present in the section.
