The Study Of Compaction Using Seismic Velocity Analyses In East - Baghdad Oil Field (Mid - Iraq)

Abstract

The present study deals with estimation of empirical equations relating travel time (T) and transit time (T.T) with depth (Z) which are expressed in the forms : T = BZN + A, log T. T. = - s log Z + H For this aim, (128) velocity analyses locations situated at seismic lines grid covering East oil field, were chooscn to deduce the above relations. The estimated equations relate the data point sets of two geologic intervals which consequently represent Cenozoic and Mcsozoic formations. Of these, two parameters N and S were deduced, plotted and presented in four contour maps for the above intervals, and then inlcrpratcd in function of compaction state.
